1 In the name of God, the Gracious, the Merciful. 2 Praise be to God, Lord of the Worlds. 3 The Most Gracious, the Most Merciful. 4 Master of the Day of Judgment. 5 It is You we worship, and upon You we call for help. 6 Guide us to the straight path. 7 The path of those You have blessed, not of those against whom there is anger, nor of those who are misguided. 2 God, there is no god but He, the Living, the Eternal. To Him belongs everything in the heavens and everything on earth. He is the Sublime, the Magnificent. Originator of the heavens and the earth. He made for you mates from among yourselves, and pairs of animals, by means of which He multiplies you. There is nothing like Him. He is the Hearing, the Seeing. 3 He sent down to you the Book with the Truth, confirming what came before it; and He sent down the Torah and the Gospel. 4 Aforetime, as guidance for mankind; and He sent down the Criterion. Those who have rejected God’s signs will have a severe punishment. God is Mighty, Able to take revenge. 5 Nothing is hidden from God, on earth or in the heaven. 6 It is He who forms you in the wombs as He wills. There is no god except He, the Almighty, the Wise. 1 Say, “He is God, the One. 2 God, the Absolute. 3 He begets not, nor was He begotten. 4 And there is none comparable to Him.” 13 To Him belongs whatever rests in the night and the day. He is the Hearing, the Knowing. 14 Say, “Shall I take for myself a protector other than God, Originator of the heavens and the earth, and He feeds and is not fed?” Say, “I am instructed to be the first of those who submit.” And do not be among the idolaters. 100 Yet they attributed to God partners-the sprites-although He created them. And they invented for Him sons and daughters, without any knowledge. Glory be to Him. He is exalted, beyond what they describe. 101 Originator of the heavens and the earth-how can He have a son when He never had a companion? He created all things, and He has knowledge of all things. 102 Such is God, your Lord. There is no god except He, the Creator of all things; so worship Him. He is responsible for everything. 103 No vision can grasp Him, but His grasp is over all vision. He is the Subtle, the Expert. 104 “Insights have come to you from your Lord. Whoever sees, it is to the benefit of his soul; and whoever remains blind, it is to its detriment. I am not a guardian over you.” 143 And when Moses came to Our appointment, and his Lord spoke to him, he said, “My Lord, allow me to look and see You.” He said, “You will not see Me, but look at the mountain; if it stays in its place, you will see Me.” But when his Lord manifested Himself to the mountain, He turned it into dust, and Moses fell down unconscious. Then, when he recovered, he said, “Glory be to you, I repent to you, and I am the first of the believers.” 144 He said, “O Moses, I have chosen you over all people for My messages and for My Words. So take what I have given you, and be one of the thankful 145 And We inscribed for him in the Tablets all kinds of enlightenments, and decisive explanation of all things. “Hold fast to them, and exhort your people to adopt the best of them. I will show you the fate of the sinners.” 36 To every community We sent a messenger: “Worship God, and avoid idolatry.” Some of them God guided, while others deserved misguidance. So travel through the earth, and see what the fate of the deniers was. 16 And mention in the Scripture Mary, when she withdrew from her people to an eastern location. 17 She screened herself away from them, and We sent to her Our spirit, and He appeared to her as an immaculate human. 18 She said, “I take refuge from you in the Most Merciful, should you be righteous.” 19 He said, “I am only the messenger of your Lord, to give you the gift of a pure son.” 20 She said, “How can I have a son, when no man has touched me, and I was never unchaste?” 21 He said, “Thus said your Lord, `It is easy for Me, and We will make him a sign for humanity, and a mercy from Us. It is a matter already decided.'“ 22 So she carried him, and secluded herself with him in a remote place. 23 The labor-pains came upon her, by the trunk of a palm-tree. She said, “I wish I had died before this, and been completely forgotten.” 24 Whereupon he called her from beneath her: “Do not worry; your Lord has placed a stream beneath you. 25 And shake the trunk of the palm-tree towards you, and it will drop ripe dates by you.” 26 “So eat, and drink, and be consoled. And if you see any human, say, ‘I have vowed a fast to the Most Gracious, so I will not speak to any human today.'“ 27 Then she came to her people, carrying him. They said, “O Mary, you have done something terrible. 28 O sister of Aaron, your father was not an evil man, and your mother was not a whore.” 29 So she pointed to him. They said, “How can we speak to an infant in the crib?” 30 He said, “I am the servant of God. He has given me the Scripture, and made me a prophet. 31 And has made me blessed wherever I may be; and has enjoined on me prayer and charity, so long as I live. 32 And kind to my mother, and He did not make me a disobedient rebel. 33 So Peace is upon me the day I was born, and the day I die, and the Day I get resurrected alive.” 34 That is Jesus son of Mary-the Word of truth about which they doubt. 35 It is not for God to have a child-glory be to Him. To have anything done, He says to it, “Be,” and it becomes. 36 “God is my Lord and your Lord, so worship Him. That is a straight path.” 37 But the various factions differed among themselves. So woe to those who disbelieve from the scene of a tremendous Day. 38 Listen to them and watch for them the Day they come to Us. But the wrongdoers today are completely lost. 39 And warn them of the Day of Regret, when the matter will be concluded. Yet they are heedless, and they do not believe. 40 It is We who will inherit the earth and everyone on it, and to Us they will be returned. 41 And mention in the Scripture Abraham. He was a man of truth, a prophet. 42 He said to his father, “O my father, why do you worship what can neither hear, nor see, nor benefit you in any way? 43 O my father, there has come to me knowledge that never came to you. So follow me, and I will guide you along a straight way. 44 O my father, do not worship the devil. The devil is disobedient to the Most Gracious. 45 O my father, I fear that a punishment from the Most Gracious will afflict you, and you become an ally of the devil.” 46 He said, “Are you renouncing my gods, O Abraham? If you do not desist, I will stone you. So leave me alone for a while.” 47 He said, “Peace be upon you. I will ask my Lord to forgive you; He has been Kind to me. 48 And I will withdraw from you, and from what you pray to instead of God. And I will pray to my Lord, and I hope I will not be disappointed in my prayer to my Lord.” 49 When he withdrew from them, and from what they worship besides God, We granted him Isaac and Jacob. And each We made a prophet. 50 And We gave them freely of Our mercy, and gave them a noble reputation of truth. 51 And mention in the Scripture Moses. He was dedicated. He was a messenger and a prophet. 52 And We called him from the right side of the Mount, and brought him near in communion. 53 And We granted him, out of Our mercy, his brother Aaron, a prophet. 54 And mention in the Scripture Ishmael. He was true to his promise, and was a messenger, a prophet. 55 And he used to enjoin on his people prayer and charity, and he was pleasing to his Lord. 56 And mention in the Scripture Enoch. He was a man of truth, a prophet. 57 And We raised him to a high position. 58 These are some of the prophets God has blessed, from the descendants of Adam, and from those We carried with Noah, and from the descendants of Abraham and Israel, and from those We guided and selected. Whenever the revelations of the Most Gracious are recited to them, they would fall down, prostrating and weeping. 59 But they were succeeded by generations who lost the prayers and followed their appetites. They will meet perdition. 60 Except for those who repent, and believe, and act righteously. These will enter Paradise, and will not be wronged in the least. 61 The Gardens of Eden, promised by the Most Merciful to His servants in the Unseen. His promise will certainly come true. 62 They will hear no nonsense therein, but only peace. And they will have their provision therein, morning and evening. 63 Such is Paradise which We will give as inheritance to those of Our servants who are devout. 64 “We do not descend except by the command of your Lord. His is what is before us, and what is behind us, and what is between them. Your Lord is never forgetful.” 65 Lord of the heavens and the earth and what is between them. So worship Him, and persevere in His service. Do you know of anyone equal to Him? 111 And say, “Praise be to God, who has not begotten a son, nor has He a partner in sovereignty, nor has He an ally out of weakness, and glorify Him constantly.” 85 Whoever seeks other than Islam as a religion, it will not be accepted from him, and in the Hereafter he will be among the losers. Read The Quran “I am to you a clear warner.” “That you shall worship none but God. I fear for you the agony of a painful Day.”

Can you install a separate 24v inverter to a buss bar off the Growatt and plug a 24/7 appliance into it? You can leave the Growatt inverter off but still use the MPPT? I'm just thinking this could be a solution when you are running small loads for an extended period such as the fridge... or have poor sun thru the winter as a way to mitigate the Growatt 50w consumption.

So same that 50w idle If you turn the dc to ac inverter off it still is capable of charging the battery over the mppt solar. So yeah you could hook anything up to your battery to run your DC loads.

That would take 20 5kwh server rack batteries, at 1.7k each that's 35k in batteries alone, and you can't even use them to tow a trailer!

Interesting vid & info mate. Have you considered converting the fridge to 12v/24v compressor, or just buying a 12v/24v fridge and use a 48v-24v DC converter to mitigate the 50W loss of the inverter, not cheap, but neither are batteries. Absorption type fridges are not very efficient in a van for the convenience of having the gas aspect, a DC compressor fridge will be much more efficient when using batteries negating the need for an inverter idle loss. There are other issues with household fridges, not the least is if it has a electric element defrost cycle. Cheers

Im curious as to your thoughts on modifying the fridge by disconnecting the internal freezer de-froster. I have read that this is a major source of power draw on a fridge over 24hr. You could modify your fridge by wiring in a manual switch on the defrost heater circuit so that if you had to go on solar for a few days during an extended outage, you could switch off the defroster. I have some experience with diy solar myself and have noticed that pretty much anything with a heating element, even small ones, really sucks up the power form the batteries. Im mulling over the idea of doing a full size fridge with no defroster on my off-grid cabin.

The one thing that was not included in the video was that the newer fridges have a defrosting cycle. Each fridge determines when that defrost cycle will run and is not on a set schedule. I just looked at my 24 hour graph for my home fridge and it did not show that the defroster cycle was activated yesterday. The defroster cycle is a battery killer. I could keep going day by day to see when the last time it ran, but unfortunately, I am rerunning 8AWG wire from the service panel to where I will be parking the RV in a few months. Yesterday my home fridge shows 1.5kW for the 24 hour time frame. Not to bad. A few years ago a fellow member of an RV forum asked if there was a way to control the defrost setting in his 5th wheel. It was a Frigidaire and he sent me the wiring diagram. I sent him a wiring diagram with parts list that would disable the defrost mode when the 5th wheel did not have 120VAC and was running off his batteries/Solar. He said it worked perfectly. I still like the LP/Electric fridge in the RV. Good Video.

Thanks for the comment. My RV fridge is super inefficient. It runs on propane or electricity. When I switch it to electricity it consumes 300 to 400 watts idle. And it doesn't seem like it ever shuts down.. it's a constant draw. My sister has a new RV and they put a pure Electric fridge in her's. I think it's because the propane/electric ones are just inefficient. I wonder if it's related to my defroster?

Hi, very interesting, however with a 50W idle consumption of you invertor and an (estimated) on duty cycle of you fridge (thermostate), you could -if fridge or freezer is only thing you are powering with this invertor - use a timer switch/clock , which switches invertor off for an hr and on for an hr etc reducing idle loss from 50*24 to 50*12 is a 600Wh saving in a 24 hr period helping to extend your off grid time capacity... Another thing you could is to set fridge/ freezer thermostate lower during sunny period of day using - when battery is full - your solar panel power to cool "deeper" during day and such reducing battery load during night as "buffered" cold inside fridge/freezer will reduce (after sun goes to sleep) time that thermostate goes on again... (of course you might need a momentary on push button if you want inside light goes on when you open door..)

Will Prowse has mentioned that 48v will kill you because in practice, it really throws over 50. Explorist has said that you can’t hook multi-strand wire under your outlet screws. He uses the little fork connectors. Some of the reviews on that combiner box say the wire gauge is undersized…I guess that one depends on lots of factors. I don’t have any opinions on this myself but curious about your thoughts. I’m really looking forward to seeing how you hook it all up to the house.

Thanks for the comment. Sorry for the late reply. I really like to 48v systems. Yes, it's higher voltage but It's only on the 2 wires connecting the battery and the inverter. It's easy to turn the power off while you hook those up and then you can cover them so it's safe. The rest of they system is on 120 volts(which can kill you also) but the low voltage what runs throughout my entire RV is still 12v which is coming off my step-down converter. Can you send me the video where Explorist said that you can't hook multi-strand wire under your outlet screws. That's interesting. I haven't looked into the wires for that combiner box. I read the review of the guy who swapped out the breakers for larger ones and then noticed things were hot...WOW. that's very dangerious. They sold it on signature solar's site so I'm pretty sure it's fine. They are very short wires so they don't need to be as thick as wires you would use for longer length runs. It's been good for me.

I have a great suggestion to make your system more efficient . With my 302L fridge freezer combination, I get 11-13hours use out of my 1280wh battery. If I had a 5120wh battery, mhen, I will be getting almost 44hours use. Your growatt inverter is a waste of power. To save your power, get a smaller inverter. If you are lucky and you use an inverter fridge like mine(you can look that up), you don't need more than a 300w inverter which is what I use. My fridge is an inverter fridge… meaning when I put it on, the compressor does not kick off immediately creating a power surge. It climbs from 0watt to 80watt gradually then drops down back to about 48watt. So I can easily power it with a 300w inverter which is very very efficient. I even sometimes still power my small home appliances with the fridge and I can still squeeze out about 10hours of use with a 1280wh battery. So in your case, if your fridge isn’t an inverter fridge, get a 1000w inverter. This will be way more efficient and you will be able to get more time out of your battery. All in one inverters are usually power hungry.

If your fridge is consuming less than 200 watts, then you are better off using a small 300 watt inverter with a 12V battery. It would me FAR more efficient than the Growatt (and less expensive). I think the Growatt type charger/inverter all in ones should not be used unless your energy demands are greater than 1000 watts. Anything lower and you probably should use a 12 or 24V system.

Seeing you are using a 3 kW inverter and a trailer, what about setting up TT-30 plug and say a 100 ft TT-30 extension cord, just reverse it to go to your home? From here, try powering your whole kitchen for 24 hours with the solar panels on. The idea being just demonstrating you can do all of your kitchen stuff for a day without overloading the inverter and without too much voltage drop over the 100 ft TT-30 extension cord say during an extended power outage. I mean a fridge is a nice start, but then you get into using things like your microwave oven, toaster oven, blender, rice cooker, air fryer, induction burner, etc because you also want to eat that food you have, not just preserve it until the grid power comes back. One thing to spice it up is to get a comparable output inverter generator, say a 4 kW, max, ~3 kW continuous portable generator and compare how the generator handles the bursty loads kitchen appliances will put on it versus your 3 kW inverter. This in particular may be a real eye opener to people as my testing around this came up with the generator, even going the inverter generator route, has some real issues with this. I think an inverter running off say that server rack battery you have will handle it a whole lot better because you have instant power from the battery where a generator needs to spool up and down and adjust its throttle, which takes time while the load shifts from kitchen appliances are instantaneous and often surge on startup from hard starting motors. Then when you go camping, you will have the outlets and extension cable ready to plug in at powered camping spots or if it is overcast and an off-grid camping spot, maybe you could run the generator to recharge your batteries and coast for a while. Could be particularly interesting if you could setup an electric start generator to automatically run as your batteries went down and only run during national park allowed hours. May be a bit of a project, but highly useful to have the automation and comply with national park regulations.

To Him belongs everything in the heavens and everything on earth. He is the Sublime, the Magnificent. Originator of the heavens and the earth. He made for you mates from among yourselves, and pairs of animals, by means of which He multiplies you. There is nothing like Him. He is the Hearing, the Seeing. 3 He sent down to you the Book with the Truth, confirming what came before it; and He sent down the Torah and the Gospel. 4 Aforetime, as guidance for mankind; and He sent down the Criterion. Those who have rejected God’s signs will have a severe punishment. God is Mighty, Able to take revenge. 5 Nothing is hidden from God, on earth or in the heaven. 6 It is He who forms you in the wombs as He wills. There is no god except He, the Almighty, the Wise. 1 Say, “He is God, the One. 2 God, the Absolute. 3 He begets not, nor was He begotten. 4 And there is none comparable to Him.” 13 To Him belongs whatever rests in the night and the day. He is the Hearing, the Knowing. 14 Say, “Shall I take for myself a protector other than God, Originator of the heavens and the earth, and He feeds and is not fed?” Say, “I am instructed to be the first of those who submit.” And do not be among the idolaters. 100 Yet they attributed to God partners-the sprites-although He created them. And they invented for Him sons and daughters, without any knowledge. Glory be to Him. He is exalted, beyond what they describe. 101 Originator of the heavens and the earth-how can He have a son when He never had a companion? He created all things, and He has knowledge of all things. 102 Such is God, your Lord. There is no god except He, the Creator of all things; so worship Him. He is responsible for everything. 103 No vision can grasp Him, but His grasp is over all vision. He is the Subtle, the Expert. 104 “Insights have come to you from your Lord. Whoever sees, it is to the benefit of his soul; and whoever remains blind, it is to its detriment. I am not a guardian over you.” 143 And when Moses came to Our appointment, and his Lord spoke to him, he said, “My Lord, allow me to look and see You.” He said, “You will not see Me, but look at the mountain; if it stays in its place, you will see Me.” But when his Lord manifested Himself to the mountain, He turned it into dust, and Moses fell down unconscious. Then, when he recovered, he said, “Glory be to you, I repent to you, and I am the first of the believers.” 144 He said, “O Moses, I have chosen you over all people for My messages and for My Words. So take what I have given you, and be one of the thankful 145 And We inscribed for him in the Tablets all kinds of enlightenments, and decisive explanation of all things. “Hold fast to them, and exhort your people to adopt the best of them. I will show you the fate of the sinners.” 36 To every community We sent a messenger: “Worship God, and avoid idolatry.” Some of them God guided, while others deserved misguidance. So travel through the earth, and see what the fate of the deniers was. 16 And mention in the Scripture Mary, when she withdrew from her people to an eastern location. 17 She screened herself away from them, and We sent to her Our spirit, and He appeared to her as an immaculate human. 18 She said, “I take refuge from you in the Most Merciful, should you be righteous.” 19 He said, “I am only the messenger of your Lord, to give you the gift of a pure son.” 20 She said, “How can I have a son, when no man has touched me, and I was never unchaste?” 21 He said, “Thus said your Lord, `It is easy for Me, and We will make him a sign for humanity, and a mercy from Us. It is a matter already decided.'“ 22 So she carried him, and secluded herself with him in a remote place. 23 The labor-pains came upon her, by the trunk of a palm-tree. She said, “I wish I had died before this, and been completely forgotten.” 24 Whereupon he called her from beneath her: “Do not worry; your Lord has placed a stream beneath you. 25 And shake the trunk of the palm-tree towards you, and it will drop ripe dates by you.” 26 “So eat, and drink, and be consoled. And if you see any human, say, ‘I have vowed a fast to the Most Gracious, so I will not speak to any human today.'“ 27 Then she came to her people, carrying him. They said, “O Mary, you have done something terrible. 28 O sister of Aaron, your father was not an evil man, and your mother was not a whore.” 29 So she pointed to him. They said, “How can we speak to an infant in the crib?” 30 He said, “I am the servant of God. He has given me the Scripture, and made me a prophet. 31 And has made me blessed wherever I may be; and has enjoined on me prayer and charity, so long as I live. 32 And kind to my mother, and He did not make me a disobedient rebel. 33 So Peace is upon me the day I was born, and the day I die, and the Day I get resurrected alive.” 34 That is Jesus son of Mary-the Word of truth about which they doubt. 35 It is not for God to have a child-glory be to Him. To have anything done, He says to it, “Be,” and it becomes. 36 “God is my Lord and your Lord, so worship Him. That is a straight path.” 37 But the various factions differed among themselves. So woe to those who disbelieve from the scene of a tremendous Day. 38 Listen to them and watch for them the Day they come to Us. But the wrongdoers today are completely lost. 39 And warn them of the Day of Regret, when the matter will be concluded. Yet they are heedless, and they do not believe. 40 It is We who will inherit the earth and everyone on it, and to Us they will be returned. 41 And mention in the Scripture Abraham. He was a man of truth, a prophet. 42 He said to his father, “O my father, why do you worship what can neither hear, nor see, nor benefit you in any way? 43 O my father, there has come to me knowledge that never came to you. So follow me, and I will guide you along a straight way. 44 O my father, do not worship the devil. The devil is disobedient to the Most Gracious. 45 O my father, I fear that a punishment from the Most Gracious will afflict you, and you become an ally of the devil.” 46 He said, “Are you renouncing my gods, O Abraham? If you do not desist, I will stone you. So leave me alone for a while.” 47 He said, “Peace be upon you. I will ask my Lord to forgive you; He has been Kind to me. 48 And I will withdraw from you, and from what you pray to instead of God. And I will pray to my Lord, and I hope I will not be disappointed in my prayer to my Lord.” 49 When he withdrew from them, and from what they worship besides God, We granted him Isaac and Jacob. And each We made a prophet. 50 And We gave them freely of Our mercy, and gave them a noble reputation of truth. 51 And mention in the Scripture Moses. He was dedicated. He was a messenger and a prophet. 52 And We called him from the right side of the Mount, and brought him near in communion. 53 And We granted him, out of Our mercy, his brother Aaron, a prophet. 54 And mention in the Scripture Ishmael. He was true to his promise, and was a messenger, a prophet. 55 And he used to enjoin on his people prayer and charity, and he was pleasing to his Lord. 56 And mention in the Scripture Enoch. He was a man of truth, a prophet. 57 And We raised him to a high position. 58 These are some of the prophets God has blessed, from the descendants of Adam, and from those We carried with Noah, and from the descendants of Abraham and Israel, and from those We guided and selected. Whenever the revelations of the Most Gracious are recited to them, they would fall down, prostrating and weeping. 59 But they were succeeded by generations who lost the prayers and followed their appetites. They will meet perdition. 60 Except for those who repent, and believe, and act righteously. These will enter Paradise, and will not be wronged in the least. 61 The Gardens of Eden, promised by the Most Merciful to His servants in the Unseen. His promise will certainly come true. 62 They will hear no nonsense therein, but only peace. And they will have their provision therein, morning and evening. 63 Such is Paradise which We will give as inheritance to those of Our servants who are devout. 64 “We do not descend except by the command of your Lord. His is what is before us, and what is behind us, and what is between them. Your Lord is never forgetful.” 65 Lord of the heavens and the earth and what is between them. So worship Him, and persevere in His service. Do you know of anyone equal to Him? 111 And say, “Praise be to God, who has not begotten a son, nor has He a partner in sovereignty, nor has He an ally out of weakness, and glorify Him constantly.” 85 Whoever seeks other than Islam as a religion, it will not be accepted from him, and in the Hereafter he will be among the losers. Read The Quran “I am to you a clear warner.” “That you shall worship none but God. I fear for you the agony of a painful Day.”

@free-qe6wx 10 ай бұрын

Few observations. There are power losses associated with the DC to AC conversion that are significant. Generally speaking, at the lower end of the draw on the inverter the conversion efficiently is terrible. It is not unusual to see around a 5kWh drawdown from the batteries to provide around 3kWh for only a residential style refrigerator over a 24 hour period. Especially if its hot and that fridge compressor needs to run most of the time, which it will inside a relatively poor insulated RV (vs a house). This is the main reason why residential style refrigerators should be avoided like the plague in RV's, unless your idea of camping is to always be on unmetered shore power.

@diySolarPowerFunWithRay My 8 cuft absorption fridge uses less than 10W when on propane. A 30lb propane tank lasts about 25-30 days when only running this fridge. Anyway, what I am pointing out is that your fridge does not actually consume a mere "100W" in your test. It is a lot more than that. Solar panels lose a lot of energy as heat during power generation. Solar charger losses. Losses internal to the battery when being charged. Losses internal to the battery when discharging. Battery self-discharge losses. Losses in the DC to AC inversion. Your monitoring/control system also consumes energy. To make available that "100W" to your fridge means you have to produce via solar a lot more than that amount when all the losses are considered. This generally gets more efficient with bigger loads, because the baseline losses stay about the same. For RV-ing, it is better to stay with the RV absorption fridge on propane and turn off your AC power system until it is needed for cooking, A/C, etc. Although, in that scenario, you will end up needing a small generator at some point unless you spend megabucks on dozens of kWh's worth of batteries and 5000W of panels. The whole thing is crazy.

I wasn't aware of a "Inverter-Type" fridge. But I can see that my fridge is turning on and off when looking at the my battery monitor... So I think that means it's a condenser type and not the inverter type.

Sorry, I'm totally blowing up your comments here. But I found you because I was searching for videos specifically for the Growatt. It's the one I want to buy. But 40% efficiency is awful. Manufacturer's spec is in the 90s. I was so close to buying this unit that I contacted Signature Solar to ask them about it and they are pretty baffled. Do you have any idea why the efficiency is so bad?

@diySolarPowerFunWithRay 10 ай бұрын

I personally like the growatt 3000 48p model better. It does better in shade. I am out camping right now and this morning I had two full 315 watt panels in the Sun and that wasn't enough to get the inverter to generate any real power. It only really functions well when I have four panels with sun. Not super awesome. But I guess it depends on what you're using it for. And how many panels are you going to connect. I would say that the idle is about center of the pack. Some of the low frequency mppt all in one brand systems consume 100 watt to idle. The 50 W idle is not a big deal to me. It's basically just an extra 100 watt panel on top of my solar array. That will cancel the inefficiencies out. Any inverter you have can have a really bad efficiency rating if you plug a small enough load into it. Really if you have an inverter on with no power it will eventually run the battery dead and you'll have a 0% efficiency rating out of the system. That's an interesting question though I wonder if IThat's an interesting question though.. If I subtract the inverter idle consumption I wonder if I hit a 90% efficiency. That would be interesting to measure. I thought I heard somewhere that inverters are most efficient when they are running at a 70% load.

1 In the name of God, the Gracious, the Merciful. 2 Praise be to God, Lord of the Worlds. 3 The Most Gracious, the Most Merciful. 4 Master of the Day of Judgment. 5 It is You we worship, and upon You we call for help. 6 Guide us to the straight path. 7 The path of those You have blessed, not of those against whom there is anger, nor of those who are misguided. 2 God, there is no god but He, the Living, the Eternal. To Him belongs everything in the heavens and everything on earth. He is the Sublime, the Magnificent. Originator of the heavens and the earth. He made for you mates from among yourselves, and pairs of animals, by means of which He multiplies you. There is nothing like Him. He is the Hearing, the Seeing. 3 He sent down to you the Book with the Truth, confirming what came before it; and He sent down the Torah and the Gospel. 4 Aforetime, as guidance for mankind; and He sent down the Criterion. Those who have rejected God’s signs will have a severe punishment. God is Mighty, Able to take revenge. 5 Nothing is hidden from God, on earth or in the heaven. 6 It is He who forms you in the wombs as He wills. There is no god except He, the Almighty, the Wise. 1 Say, “He is God, the One. 2 God, the Absolute. 3 He begets not, nor was He begotten. 4 And there is none comparable to Him.” 13 To Him belongs whatever rests in the night and the day. He is the Hearing, the Knowing. 14 Say, “Shall I take for myself a protector other than God, Originator of the heavens and the earth, and He feeds and is not fed?” Say, “I am instructed to be the first of those who submit.” And do not be among the idolaters. 100 Yet they attributed to God partners-the sprites-although He created them. And they invented for Him sons and daughters, without any knowledge. Glory be to Him. He is exalted, beyond what they describe. 101 Originator of the heavens and the earth-how can He have a son when He never had a companion? He created all things, and He has knowledge of all things. 102 Such is God, your Lord. There is no god except He, the Creator of all things; so worship Him. He is responsible for everything. 103 No vision can grasp Him, but His grasp is over all vision. He is the Subtle, the Expert. 104 “Insights have come to you from your Lord. Whoever sees, it is to the benefit of his soul; and whoever remains blind, it is to its detriment. I am not a guardian over you.” 143 And when Moses came to Our appointment, and his Lord spoke to him, he said, “My Lord, allow me to look and see You.” He said, “You will not see Me, but look at the mountain; if it stays in its place, you will see Me.” But when his Lord manifested Himself to the mountain, He turned it into dust, and Moses fell down unconscious. Then, when he recovered, he said, “Glory be to you, I repent to you, and I am the first of the believers.” 144 He said, “O Moses, I have chosen you over all people for My messages and for My Words. So take what I have given you, and be one of the thankful 145 And We inscribed for him in the Tablets all kinds of enlightenments, and decisive explanation of all things. “Hold fast to them, and exhort your people to adopt the best of them. I will show you the fate of the sinners.” 36 To every community We sent a messenger: “Worship God, and avoid idolatry.” Some of them God guided, while others deserved misguidance. So travel through the earth, and see what the fate of the deniers was. 16 And mention in the Scripture Mary, when she withdrew from her people to an eastern location. 17 She screened herself away from them, and We sent to her Our spirit, and He appeared to her as an immaculate human. 18 She said, “I take refuge from you in the Most Merciful, should you be righteous.” 19 He said, “I am only the messenger of your Lord, to give you the gift of a pure son.” 20 She said, “How can I have a son, when no man has touched me, and I was never unchaste?” 21 He said, “Thus said your Lord, `It is easy for Me, and We will make him a sign for humanity, and a mercy from Us. It is a matter already decided.'“ 22 So she carried him, and secluded herself with him in a remote place. 23 The labor-pains came upon her, by the trunk of a palm-tree. She said, “I wish I had died before this, and been completely forgotten.” 24 Whereupon he called her from beneath her: “Do not worry; your Lord has placed a stream beneath you. 25 And shake the trunk of the palm-tree towards you, and it will drop ripe dates by you.” 26 “So eat, and drink, and be consoled. And if you see any human, say, ‘I have vowed a fast to the Most Gracious, so I will not speak to any human today.'“ 27 Then she came to her people, carrying him. They said, “O Mary, you have done something terrible. 28 O sister of Aaron, your father was not an evil man, and your mother was not a whore.” 29 So she pointed to him. They said, “How can we speak to an infant in the crib?” 30 He said, “I am the servant of God. He has given me the Scripture, and made me a prophet. 31 And has made me blessed wherever I may be; and has enjoined on me prayer and charity, so long as I live. 32 And kind to my mother, and He did not make me a disobedient rebel. 33 So Peace is upon me the day I was born, and the day I die, and the Day I get resurrected alive.” 34 That is Jesus son of Mary-the Word of truth about which they doubt. 35 It is not for God to have a child-glory be to Him. To have anything done, He says to it, “Be,” and it becomes. 36 “God is my Lord and your Lord, so worship Him. That is a straight path.” 37 But the various factions differed among themselves. So woe to those who disbelieve from the scene of a tremendous Day. 38 Listen to them and watch for them the Day they come to Us. But the wrongdoers today are completely lost. 39 And warn them of the Day of Regret, when the matter will be concluded. Yet they are heedless, and they do not believe. 40 It is We who will inherit the earth and everyone on it, and to Us they will be returned. 41 And mention in the Scripture Abraham. He was a man of truth, a prophet. 42 He said to his father, “O my father, why do you worship what can neither hear, nor see, nor benefit you in any way? 43 O my father, there has come to me knowledge that never came to you. So follow me, and I will guide you along a straight way. 44 O my father, do not worship the devil. The devil is disobedient to the Most Gracious. 45 O my father, I fear that a punishment from the Most Gracious will afflict you, and you become an ally of the devil.” 46 He said, “Are you renouncing my gods, O Abraham? If you do not desist, I will stone you. So leave me alone for a while.” 47 He said, “Peace be upon you. I will ask my Lord to forgive you; He has been Kind to me. 48 And I will withdraw from you, and from what you pray to instead of God. And I will pray to my Lord, and I hope I will not be disappointed in my prayer to my Lord.” 49 When he withdrew from them, and from what they worship besides God, We granted him Isaac and Jacob. And each We made a prophet. 50 And We gave them freely of Our mercy, and gave them a noble reputation of truth. 51 And mention in the Scripture Moses. He was dedicated. He was a messenger and a prophet. 52 And We called him from the right side of the Mount, and brought him near in communion. 53 And We granted him, out of Our mercy, his brother Aaron, a prophet. 54 And mention in the Scripture Ishmael. He was true to his promise, and was a messenger, a prophet. 55 And he used to enjoin on his people prayer and charity, and he was pleasing to his Lord. 56 And mention in the Scripture Enoch. He was a man of truth, a prophet. 57 And We raised him to a high position. 58 These are some of the prophets God has blessed, from the descendants of Adam, and from those We carried with Noah, and from the descendants of Abraham and Israel, and from those We guided and selected. Whenever the revelations of the Most Gracious are recited to them, they would fall down, prostrating and weeping. 59 But they were succeeded by generations who lost the prayers and followed their appetites. They will meet perdition. 60 Except for those who repent, and believe, and act righteously. These will enter Paradise, and will not be wronged in the least. 61 The Gardens of Eden, promised by the Most Merciful to His servants in the Unseen. His promise will certainly come true. 62 They will hear no nonsense therein, but only peace. And they will have their provision therein, morning and evening. 63 Such is Paradise which We will give as inheritance to those of Our servants who are devout. 64 “We do not descend except by the command of your Lord. His is what is before us, and what is behind us, and what is between them. Your Lord is never forgetful.” 65 Lord of the heavens and the earth and what is between them. So worship Him, and persevere in His service. Do you know of anyone equal to Him? 111 And say, “Praise be to God, who has not begotten a son, nor has He a partner in sovereignty, nor has He an ally out of weakness, and glorify Him constantly.” 85 Whoever seeks other than Islam as a religion, it will not be accepted from him, and in the Hereafter he will be among the losers. Read The Quran “I am to you a clear warner.” “That you shall worship none but God. I fear for you the agony of a painful Day.”

The 50 watt idle equates to 1200 watts per day or about an hour of sun hitting my small solar array. It's a tough decision. With the money you could save you could buy another solar panel to off set the losses. I'm leaning towards the more efficient inverters for smaller loads where you may not have solar around to off set the losses.

@obnox7601 9 ай бұрын

Good video, but I question the results. You show a measured overall efficiency of 55%. If you lose 2% over the extension cord that means the inverter/battery combo is losing almost 43% of the power. That makes no sense at all, sorry. If that's true there is something wrong with your sysem. Newer inverter/batteries combos are in the high 90's percentage wise of efficiency. I suspect your kilowatt measuring devices are wrong. I know for a fact my fridge (looks just like yours) draws 6 amps when it's running which is about 720 watts. Something doesn't compute!!

@diySolarPowerFunWithRay 9 ай бұрын

It is more efficient if you have a larger load. I think I heard 70% efficiency is best. I could have a super light load and all the power would be going into keeping the inverter running... It that case I could get 10% efficiently. Or if you don't have a load connected at all and the inverter is just idling you'd get a 0% efficiency because no power went to something useful. I didn't do a good job explaining this in this video.

@nw-bound2413 11 ай бұрын

It works the same for AC as for DC power. The difference here is that what causes the high power loss is the higher current for the DC low voltage. AC power is either 120V or 240V, and that higher voltage means less current required than DC power at 24V or 48V. The higher the voltage, the lesser current (amps) and the less ohmic loss for the same power.

It really depends on how heavy of a load you have connected to the inverter. For example, Lets say I don't connect anything to the inverter(a super light load)... eventually with the inverter on, it will run the battery down to zero. In that case you'd have 100% battery loss by the inverter. Lead acid will produce the same results.

This is the money for electrical bill of a fridge in 8 years. You can't even save the money for the inverter, not including battery, solar power which is not always available enough to keep up with with 1.2kwh consumption per day from the solar battery and inverter.

All monitors, computers are dc. 98% in a house is DC. The solar system must have the highest voltage in the dc range. Because all dc conversion must be made on step down (buck converters). 48v-60v buck converters step down efficiently to 24v, 12v and 5v for all your needs.
