[@notyoung]

Thank you - someone putting together a practical system ;-) Charge controllers usually have a heat sink that's designed for vertical operation. Even when testing, you should have the controller vertical for proper convection airflow. If not, you need some serious air movement - probably a minimum of 150-200CFM from a fan that matches the width of the heatsink. If not adequately cooled, good controllers usually have thermal rollback or shutdown when it gets too hot.

[@ProjectsWithDave]

Thanks! Yes, you are right, vertical mounting is the best for heat dissipation.

[@2011italianoboy]

This was the best DIY video I've seen. I especially like how it was tested on various tools. I'd love to do a DIY, but for the cost and my needs, I just may go with an already built system. I plan on just using it for camping, and when I do lose power, use this system for a freezer and a refrigerator. This way, I'm not constantly running the gas generator. I really appreciate you putting a well thought out and detailed video.

[@ProjectsWithDave]

[@henrilehren]

Great summary Dave for assortment of basic yet capable starter options. I survived hurricane Sandy for 7 days, on a 1500W inverter tethered off the car, with a 10 mo old baby at home. I think the car / inverter setup has BIG advantages over a small generator setup too! I even saved someone with the same inverter that had no power with a sump pump.... You can run minimum energy "quietly" overnight still having essentials running - and don't have cans and cans of gasoline! Would like to hear your opinion of PURE SINEWAVE vs SQUAREWAVE inverters - like what a Sqr Wave wrecks? GREAT CONTENT for those scouts who want to "be prepared", while maybe learning something along the way (with their kids to boot) ! ! ! 👍👍

Excellent video. Some specific ideas to consider are: pre-charging the capacitors in the inverter prior to, securing the PV cable down so they do not get pulled out or stress the terminals. I use a battery disconnect in addition to breakers. Do not take my comments as criticism or complaints. Just throwing in some ideas!

[@rodgough4581]

Awesome info! Another advantage of the self assembled, is that if one aspect off the system stops working, it can be easily replaced or upgraded as you go.Thanks.

[@ProjectsWithDave]

Yes, and you can modify as your needs change over time.

[@paulbaker3144]

I bought my first solar generator exactly 30 years ago from CC Crane Co. it was in a ammo box and came with a small solar panel. I’ve since made a few myself. My favorite one was a rolling one on a large garden cart. It was designed to help the farmer or gardener. It had a car stereo, phone charging, power for water pump, and power for anything needed. It also had room to place tools and materials. I’m going to build that has electric propulsion and can tow another cart full of mulch, gravel, or whatever. A lot of work can get done by small electric equipment. Heavy tractors and excavators aren’t always needed and if one has this equipment it’s tempting to use it for jobs where it’s not really needed.

[@bonezed]

[@68HC060]

Quality channel with correct information. It's rare to see these days. :) I was especially impressed by Jordan's knowledge. One thing you may want to do, is to have a 'precharge' breaker, where you mount the resistor in the system, so you can flick on the precharge first, then when the capacitors are charged, you can flick on the other breaker and flick off the precharge breaker. To see if the capacitors have been precharged, you could likely just add a LED and a resistor over the power-resistor; when the LED turns off, the capacitors would be charged. I'm also happy you recommend the LiFePO4 batteries; they're (currently) the best and safest of the affordable battery types available. Edit: It may be a good idea to write the "in-order checklist" on the device, so you never forget the steps for turning it on / off.

[@ProjectsWithDave]

I like your idea of building in a pre-charge circuit.

[@68HC060]

​@@ProjectsWithDave - I forgot to mention that a good resistor value for a LED connected to 12V would be 1K Ohm or above. It might be necessary to create a 'resistor ladder' to be able to adjust when the LED should turn off, though. If you're lucky, it'll just work with the 1K in series with the LED. The 1K resistor can be any 0.25Watt you have laying around.

[@termiterasin]

EXTREMELY COOL video. A big question in my mind has always been AIO units vs DIY, and this is the first build I've seen someone make a portable DIY!

[@ProjectsWithDave]

Thanks! I'm glad it was helpful.

[@vinniec5286]

Wow! Extremely well done and informative video, sir. I have been experimenting with an almost identical setup and I use a resistor when first connecting the inverter to the battery, but I had NO idea that the in-rush of current into the inverter was that high when first powered on!

[@ProjectsWithDave]

Glad it was helpful!

[@dol3980]

I think this system works well with light resistive loads BUT forget inductive loads and he mentions this at the end, but I doubt this setup will meet the critical test of life cycle and longevity. test with frequent cycling at different harmonics.

[@johnfitbyfaithnet]

​@dol3980 how did you set up your system differently? Please

[@theraylfamily4520]

You can tap battery banks to get 24 V or even 48 V etc. and if you have 12 V devices you can run special taps off the battery banks to use 12 V. Take a look at golf carts. They have a lot of batteries to have high voltage for the motors, but then they’re tapped at 12 V for the lights.

[@ProjectsWithDave]

You have to be careful with that strategy, it causes imbalance in the battery capacities.

[@chrism5508]

Most 36-48 volt systems that also have 12volt systems use a step down converter instead of tapping a single battery. This prevents imbalance in the batteries. They also do this because some carts used 6x 8 volt batteries which wouldn't allow a 12volt source

[@scottpeal60]

Wow, just wow! Great video. Needed more power at my woodshop and was going to cost thousands to run new cables. Your solution is just what I needed. Will be using your links.

[@ProjectsWithDave]

Thanks, glad it helped!

[@mktwatcher]

Nice video. Your Son's input though short was very helpful, especially about advantage of running higher DC voltage battery banks. Of course that would more expensive sense you would need additional batteries wire in series to get a 24 volt system. Thank you for sharing.

[@ProjectsWithDave]

Glad it was helpful!

[@ooglek]

Great stuff! Thrilled that you covered the inrush current on the inverter. I didn't really consider that when I built my own solar generator. I've got a 600 watt Giandel inverter, and I haven't had an issue with the Daly BMS. I'll dig into the inrush current limits on the Daly BMS to see if I can expand without replacing my BMS. Cheers!

[@ProjectsWithDave]

I didn't expect it to be that high either. I knew there would be when the batteries were first connected, but I didn't expect another jump when the unit was turned on.

[@VinceBadovinatz88]

I know I didn't know anything about in Rush

[@KevinDouglas11]

Informative video but commenting to say: Be careful microwaving water. When microwaving it can actually superheat the water without appearing to boil. When this happens water can become hotter than its boiling point without actually boiling, and when disturbed it can rapidly boil, steam, and explode. If you keep doing it put a wooden spoon or something in the water to allow the bubbles to form allowing it to boil.

[@ProjectsWithDave]

Thanks!

[@johnb4717]

You should have far more subscribers, than you do. Keep up the great presentations, & you will. Thanks. You now have 1 more. I built an all-in-one ~1.6Kwh Lithium-ion 12VDC system, incorporating an internal 1000w inverter. A little undersized, but in New Zealand, we don't have the luxury of great product diversity, & it was the only one I could find, that would fit into the toollbox, I used as my backup power supply case. A coupe of issues I experience are: -the Victron 75/15 MPPT solar charge controller, mis-reads the battery voltage, on the device app, so I have to charge at a higher voltage, than the app reads. I use a connected Cellmeter 7 balancer (voltage has been confirmed with a multimeter) to manually check the battery voltage, whilst charging. -my inverter's (Chinese one. Programmable inverters, in NZ, cost an arm, & 2 legs!) display mis-reads the battery voltage by ~0.5VDC. Not ideal. But the seller adjusted the input voltage resistor, so it reads a similar offset voltage. So the inverter does not shut down, with too much usable battery voltage left. The only appliance that does not work, is my water pump, due to the inrush voltage, on the undersized inverter. Not really a biggie, now we aren't having power cuts every other week, like we used to. Am designing 2 portable lithium-ion batteries, that can be easily connected in series/parallel, depending on the immediate needs. May be used as a permanent solution, for my pump?

[@ProjectsWithDave]

Thanks for the feedback. A 1000W inverter is good for an entry level backup, but I've found 2,000W is really the minimum if you want to manage any significant appliance. If you use a meter with inrush capability you can identify the threshold you need to achieve in order to run your pump. Also, you can look into some startup capacitors that can reduce the surge load for you. I added one to my heat pump.

[@elizabethireland6320]

[@CoolMusicToMyEars]

Very nice setup 👌 👍Very detailed 👌 👍 measurements of the inrush current is certainly very useful to know 👍

[@OffGridSolar]

I have always liked your videos but I do have a few small recommendations you may want to use for your next build like this. Code requires you have a double pole breaker between the solar panels and charge controller. You have to be able to simultaneously disconnect both the positive and negative connectors at the same time. Typically I use a 63amp Din Rail mini-breaker. The small automotive breakers don't break the connections on both poles and in a short circuit event the current could jump the negative conductor. Also you need to use fine strand flexible copper wire between the inverter and charge controller. You used what looked like THHN coarse stranded copper which can cause higher resistance and heat and it is not flexible which is harder to work with. Also many charge controller companies recommend against course strand wire. I believe bougeRV recommends against it as well. I would recommend against stacking connections on the inverter and using bus bars. You should also use either an ANL fuse or T-Class fuse between the battery and inverter (Bus bars). The breakers you chose are notoriously unreliable in high current systems. Although for such a small system they should be ok. That being said. I love the videos you do so keep up the great work.

[@ProjectsWithDave]

Thanks for the feedback. The Din Rail mini-breakers are a much better choice. I added that note to my parts breakdown on my website: projectswithdave.com/12v-1500w-diy-solar-generator/

[@bexraphaela]

Impressive video, im excited to get started for an installation like this on my boat

[@RB-lt8kt]

Good video and lots of useful information. I live in the UK and a EB55 costs £499 and EB70 at £699 (coupon gets £80 off this price). I ordered a EB55 as it offers 400W dual charging which the EB70 doesn't and only 300W DIFFERENCE IN ac INVERTER OUTPUT. Building a similar unit would cost £200 more than buying one. I am adding two 12V 36Ah batteries so can add 922Wh to the DC input while charging with solar or charging batteries. Solar panels cost £400 for four and 2 batteries cost £252. DC charger cost £50 and EPEVER solar charger cost £80 for a 20A unit. Also have a 600W pure sine wave inverter and an older 1000W pure sine wave inverter as well as a 12V to 24V step up converter. Complete system costs around £1500 including the inverters so 2 systems can be run at the same time independently and charged individually.

[@ProjectsWithDave]

Nice way to combine the standard generator with your own additional battery capacity.

[@RB-lt8kt]

@@ProjectsWithDave Yes but you need a buck converter to use the 25 to 28V input as it will not accept just 2 batteries connected in series ( about 26 volts) . I think it demands 10A but sees a higher current and will not switch the charging on. It needs a regulated input.

[@JesusOurKing]

On an extreme budget, try the Vtoman 600x. It probably won't run that 1700w espresso, but it should run most things under 1000w if they can function at 600w. A lifesaver during blackouts on the cheap.

[@kimmer6]

Great review. I have built many inverter projects and did not know they had such high inrush currents on startup. The thing that I would add to any home built unit is some kind of battery monitor that has a shunt and the ability to show battery charge percentage. I like the Renogy units. Knowing what state of charge you have in the battery is important. Without being able to monitor it is like driving a car without a working gas gauge. It leaves you guessing all the time and it can quit unexpectedly. Volt meters are poor ways to measure LFP battery state of charge.

[@ProjectsWithDave]

Great advice! Thanks!

Hi Dave. Nice comprehensive video. I would have also mentioned an off grid charging option using the charging brick and a small portable generator. I built a power cart (Wen brand utility cart) using three 200 amp Power Queen Plus LiFePo's batteries (7950 WH capacity total) coupled with a 3000 watt pure sine inverter. Each battery having it's own individual ON/OFF switch. However I do not intend on paralleling them.

[@ProjectsWithDave]

A portable generator and a power brick would work, but probably not very efficient.

[@RippingJack76]

We had a ice storm back in the 1990s. Back in those days the cable system could work if you put power to it. I make do with a Mercedes battery on a skateboard. 500 watt inverter. I took the battery out to the car to charge it. If it has lasted longer than a week I probably would have hooked up an alternator to A 6 horsepower motor.

Thanks for making common sense out solar hook up and mainly safety you point out so well. Great content and video. Just one request. Can you show how to assemble a 3000 or 5000 watt inverter 12v system please.

[@ProjectsWithDave]

A 5000W inverter with 12V would require some very large cables. Why not switch to 48V? You can still get 12V like I show in this video: kzbin.info/www/bejne/rqS9q598lLN0bKc

[@usmckozmo]

I do believe the proper circuit wiring is Solar Charge Controller > Battery > Inverter > Load What reason would you wire the inverter before the battery?

[@ProjectsWithDave]

That's correct, the standard method would use a buss bar to connect the 3 components. This setup is simply using the inverter posts in place of the buss bar to reduce complexity and cost. Setting it up this way does have some limitations.

[@jasonbroom7147]

The BMS on many batteries can go over specifications for a short amount of time, but be aware that many of these actually rely on the temperature relay cutting off discharge when the cells get too warm. A quality BMS will actually regulate the amperage instead of relying on a cheap relay that could very easily fail.

Excellent video. But, anyone planning one of these has to consider the time, tools and competence it takes to put these systems together, plus the compactness/cleanliness of a pre-made system. Even the cost is deceiving: as of 5-2-24 the Bluetti AC200P, in the video for $1,600, is on sale for $1,100! These standalones are always going on sale. The Anker C1000 with 1800 watts/1056 W hours, 600W Solar charge is $630. The Pecron E1500LFP with 2200 watts, 1536 W hours, 800W Solar charging & a 30 watt output is $800. All of them have app control via your phone, UPS and are expandable. Just saw the Pecron 2000LFP 2000W, 1920Wh, 1200W max solar, wireless charging (phone) for $850!

It is hard to beat the utility, cost and convenience of the smaller all in one units.

[@rcmodeler2]

Thanks, great video. Times they are a changin' . Bluetti 270p was just $1199 this past week. May come down lower soon. I found the KAIWEETS HT208D Inrush Clamp Meter on ebay for $56 w tax. shipped

[@ProjectsWithDave]

Wow! that's a great deal

[@kickgas7171]

Nice setup. Only one glaring flaw. After spending more than 23 years in the inverter repair industry, I would highly recommend spending a little extra money and investing in a low frequency, transformer based inverter instead of that low cost, low surge, high frequency, transformerless inverter. High frequency, transformerless inverters are not designed for powering high inductance loads such as microwave ovens, power tools or refrigerators and can be damaged or have their life considerably shortened when powering inductive loads. The problem is low cost MOSFETs that are used in these inverters that are far more sensitive to the surges that are required by these inductive loads. When powering inductive loads, you'll typically only get a year or less worth of life from a high frequency inverter whereas a low frequency inverter will typically yield 10 years or more before needing service.

[@ProjectsWithDave]

Thanks, that's a good reminder. I can tell you my low frequency Victron inverters are way better at powering inductive loads. Here is one setup I installed and tested: kzbin.info/www/bejne/eKuwcopuoLxjebc

You can use a resistor to pre-charge inverter by keeping it installed with a momentary switch, this is to charge capacitors before switching inverter on without the spike.

Thank you for this video. I'm one that debates whether or not to have a 12, 24 or 48 volt system for an inverter system to power my ac system in the radio shack. My radios use 12 volts. I may just use two different systems, a 12 volt for the radios and a 24 or 48v system for the ac system. From my limited understanding, you can take 12 volt from a 24 or 48 volt system if you wire correctly.

[@ProjectsWithDave]

I recommend you go with 48V if your radio load is not too high. Watch this video: kzbin.info/www/bejne/rqS9q598lLN0bKc

[@MattLesak]

Nice video! Great details. It’s a labor of love 😎 I built something similar on a Harbor Freight cart. I use it all time vs long extension cords. Comes in handy.

[@ProjectsWithDave]

Nice! It is actually pretty useful. My power went out just days after I built it and it was kind of fun to just run and grab it to power the fridge.

[@joshuafreeman9792]

Nice job with this I wish my renogy converter worked that good well it does as long as I don't use the power saver mode.power saver kicks the alarm constantly but they say nothing is wrong with it

[@s.mendez7160]

Given the very low internal resistance of LFP batteries, would suggest to your viewers replacing the breaker to the inverter with something that has a much higher AIC rating then the breaker shown. Class-T fuse would be a safe choice. In the event of a short, that breaker will melt itself closed, and a fire risk is highly likely. For all inverter feeds from an LFP battery, we recommend a service disconnect switch, and a Class-T fuse no longer than 7" from the LFP battery.

This is an excellent video! Thank you for posting this info. I’m now a new subscriber to your channel. Thanks again!

Thanks and welcome!

[@cheerio9119]

Just discovered you, AMAZING!! Thank you so much for sharing ❤

[@Annon89]

One thing I’d like to say is if you built a diy at similar capacity and similar inverter you would likely be about the same costs based on what you posted. I personally like having the diy because I can expand or modify my system where you can’t change the Bluetti at all. But it’s a good compare of easy to find parts vs a prebuilt solar generator even though it’s a little undersized to the diy. Larger. 1200w prebuilt are significantly more money the last time I looked.

[@ProjectsWithDave]

It all depends on what you need. Flexibility and expandability, or simple and easy. The cost continually jumps all over the place, but this at lest gives you an idea of where you will land.

I would at least tin the wire with solder for the crimped ends. Best way is to solder the loop terminals on. If you don't do one or the other the connections will loosen with use and heat cycles. Loose connections are a potential loss of efficiency and or melt down. Great ideas for portable power. I'm going to build one for my pontoon boat and back up in emergency situation such as tyrannical power grid sabotage. Alot of punch, for not a bunch!

[@housesOTR]

Great video. I have never seen a charge controller connected to the invertor. The MPPT will give out up to 14.6 volts which may cause an over voltage error depending on the invertor.

[@ProjectsWithDave]

I assume you are concerned for a condition where the battery is disconnected and only the charge controller is connected to the inverter? Yes, I should probably have mentioned it's not meant to be run that way. The setup relies on the battery to balance the load/supply to the inverter. Thanks!

[@JT-lq4yd]

In this setup, having the charge controller connected directly to the inverter should not be a problem as most inverters have a maximum input voltage greater than 15 volts, most I have seen are 15.5 and some up to 16 volts.

[@CharlesSmith-vf4hd]

Very professional home build

[@andyirons7162]

I havent watched full video but just quickly (based on experience) ---> those off the shelf power stations are insanely inefficient ...the inbuilt invertors leak so much power....I had a top end ecoflow but returned it....after many tests and application uses I was getting ~55-60% of the claimed energy (kWh or Ah) .....this was via the 240v inverter..... power usage via the 12V sockets wasnt much better...i returned the product (what a sh*t-fight that was).....building your own unit is a different beast.....you build to out specific needs, you learn so much and gain invaluable knowledge and you can get WAYYY more battery and component value for the same amount of dollars....its not all hate but when I pay $1500 for a product and it deliveres 60% of claimed benefits then that to me is a total fail / rip off.

[@scottsherwood8555]

Very useful step by step video. Thanks for posting this.

[@ronb6182]

I like the lower output voltage. Lights will last much longer at reduced voltage. If i was to run an AC unit or well pimp i would want 120 volts. But probably everything will be ok as is. Thanks for posting i would hope the charge controller would have the order of power up. Thanks for posting the power up sequence. 73
