I dont get it,this inverts are off grid,they suppose that not back feed the network back even when you have plug in AC grid as a backup!!Also on 3:30 i dont get it why he makes this?

[@georgedrenes8143]

Well done! My house is about 98% complete and I’m 100% off grid. I’ve got the same inverters and two of the auto transformers just as a precaution, should one fail. Good willing, today I’ll complete the final wiring and program the inverters. Your videos give DIYers like me confidence that an off grid farm can be powered by solar. Look forward to your next informative video. God bless you for sharing your knowledge and experiences.

This is awesome. Signature solar is 15 miles from me. I just picked up 12690 watts of solar panels 3 5K grow Watt inverters. 1 Transformer six 48 V 100 amp-hour lithium iron phosphate batteries. I just got rid of my tankless water heater and went to a 50 gallon heat pump water heater and purchased a soft start for my 3.5 ton ac. I have a 1200 square-foot home I am going to be able to run completely from this setup

[@CountryLivingExperience]

Very cool! Sounds like you have a nice big system. I just picked up a heat pump water heater that I am switching out soon too.

[@RedandAprilOff-Grid]

😎 Our inverter is 6,000 watts, it has two 3,000 watt legs. We have to be careful about what we run, but as long as we are careful, we can run what we need to. Our dryer uses over 5,000 watts by itself, so we just use it on air-dry then hang everything. Once we get our house built, we'll probably use propane for our dryer and stove.

[@CountryLivingExperience]

Very cool. Yes, it is about knowing your individual homestead and loads. That is one of the keys to success.

I have a similar setup for the same inverters. Powers most of the loads in the house except the strip heating in the furnace, the dryer and the electric stove. The AC\heat pump is connected to the system and the largest I've seen it draw was around 2.75KW. Have not had any major issues. As mentioned, if the loads are not stupidly over balanced. This setup will work very well. And I also got my inverters from SS.

[@MrButuz]

Interesting vid. A little unsure why you would not grid tie this and run of it 100% of the time with the grid as a backup feed. Seems more efficient to me. Also why move large loads to propane? That is a product likely to go up significantly in cost and become more difficult to buy in future decades and especially in a future scenario where grid may be down for a long period and everyone else using propane would want to panick buy/stockpile?

You are my wise man and an inspiration to me and my family. Thank you for all the information that you shared and we love your channel. I have 6 of the same battery’s, 5 of the Growatt 5000 and 2 Growatt transformers. I purchased everything excluding my 22,400 watts of panels from Signature Solar and I am in the middle of my install. I have a 3-1/2 ton heat pump with a soft start and I am hoping to be able to go off grid. I was wanting to stay grid tied for back up on cloudy days using the pass through but I notice you said the wiring was too complex. I have to get my install inspected so I am having a professional Electrition and independent solar installer do the work. Have you ran the batteries through the night yet and if so what percentage did you use?

[@electricandlspower]

Flipping coins I would love to see a video of that set up . Sounds really close to what I'm planning. It's unfortunate that no one is doing the pass though. In December that was my plan 100% it lowers the electric bill to the lowes but gives me the grid as instant back up. Currently have a skid of 28 435w panels and one growatt 5000es one auto transformer and 4 agm. The batteries were in a different when I purchased a trailer might as well play with them. Tell summer when the array can be installed.

You're welcome. I appreciate you being here. Sounds like you have a huge system. I have not run the batteries at night yet because I have the 3 ton heat pump running at night and the system won't handle it. As soon as I switch to the mini-split system, I will run another test.

[@zuzax1656]

That was very impressive and informative. It was fortunate that you were able to do this before converting the stove and water heater to propane, as some folks might not have that option, yet. I, for one prefer cooking with gas or propane rather than electric, but where I live, gas is practically nonexistent and propane is not widely used. One of the reasons I prefer gas/propane to electric is that here (Maine) lines can go down easily for weeks. With a gas stove/ oven, you can heat at least one room, while heating water for cooking or even bathing. I tend to plan for worst case scenarios, so even if I lived in a mild climate, I'd probably plan for Maine winters and Laredo summers. Lol.

[@CountryLivingExperience]

Thank you. I also like planning for worst case so having the propane as a redundant system was important for us. I will keep all my electric appliances for backup after converting.

[@BecomingOffgrid]

I have a similar setup and I also am not bringing in commercial power to my units. It just solves so many problems with the autotransformer, it makes sense. Also you can just put in a soft start on your 3 TON A/C unit and the inverters will start them just fine. About 400 bucks and you don't need to rebuild your whole cooling system. SS sells them and they work great.

[@CountryLivingExperience]

Cool. I couldn't justify spending money on a soft start ($400 + install) on a system that is 15 years old and has a slow leak. The mini-splits are much more efficient and if I am running them a lot when there is no sun, I want to have that efficiency.

[@BecomingOffgrid]

@@CountryLivingExperience When I was in Korea in 2002, everyone was using mini splits - they have been in Asia for the last 20 years. Your switch to mini-splits makes perfect sense to me - Mini Splits are way better and when my units die I will be switching. Not questioning your methods, just wanted to add that bit in case someone (like me) doesn't want to replace their existing home A/C units. Love watching your videos, you are doing great!

Thank you for taking the time to make this video. This was very informative. Can you tell us what kind of water heater you have? I thought most water heater elements use 5000 watts each...?

[@CountryLivingExperience]

Great question. My water heater is very old. It came with the house and is at least 20 years old from what I can tell. It has a 4500w element. WH elements can range widely in their wattage. Some are 1500 and some are 5000. My WH is most likely very inefficient too.

After doing this test, how long do you think you could run the electric loads in your house in a normal capacity if the grid was completely off? Do you think you have enough battery backup and solar to continually stay off the grid indefinitely yet?

[@CountryLivingExperience]

I can absolutely run off grid in a normal capacity without that grid once I get my heating system worked out. I could burn wood in my stove but want to get my mini-splits in. For my area, I almost have enough batteries to do that (need just a few more). Batteries are your biggest investment and you can never have too many.

[@stevepailet8258]

two short notes. better to go with an induction stove top with two burners and an additional portable 2 burner induction stove top that you can put on your counter top should you need more burners. The second thing is if you decide to add a few more panels you might wish to run the water heater that you have now with those dedicated panels or just dedicated battery and panels. dont know how many folks you have in the house showering but 4 or more is a great reason to go to a bigger tank. If you decide to go propane consider using your electric water heater as a pre heat for your propane fired. You may discover it is a rare thing that the propane fired tank rarely comes on

[@Vigo327]

Great vid. I bought two of the Growatt 5ks but haven't begun setting them up yet. I'm not sure about the issue of overall efficiency of your existing system vs mini-splits, but you SHOULD be able to run the existing system if you install a soft start on the compressor, and the overall cost of that would far less than multiple, or even one mini-split system. Just wanted to point that out for anyone else who was thinking about trying to run an existing unit like yours.

[@CountryLivingExperience]

Thank you. I am actually releasing a video on Sunday of our HVAC system vs. mini-split situation. I talk about a soft start, advantages of mini-splits, our current HVAC system, etc.

[@comingtofull-ageinchrist6736]

you converted your oven and dryer, but now you're dependent upon fuel. It seems counter productive if you're wanting to go off grid and be energy independent. What happens when you have a problem or long delay in getting propane? It would seem that adding a little to your PV system would be the smarter way to go. It would pay for itself! In Oklahoma, some utility companies offer a rebate for customers who get a generator install, and they have a smart panel that can control it and run the house on generator power during peak hours to reduce power consumption and cost, and a soft start for electric HVAC condensers to reduce start up spikes in current, which can be very high. Soft start modules are a great solution to help your Generator or P.V. system handle a larger load on start up. That could be a good solution for your situation. I personally had a Mr. Cool Mini Split 18K BTU unit and they do not do well in winter. Mine gave out in December and I installed in in March of 2021. Mini Splits are an option but not necessarily a good one, especially for heat. For a person with an existing electric heat, a soft start module may be something you want to look into to help your solar or generator handle the spike current on start up. I've installed 100's of Generac Automatic standby Generators for whole homes and using DLM's digital load management modules, and they do make wireless ones now, so you can wire you appliance through it and not have to wire it all the way back to the panel. A/C units, electric heat, dryers and water heaters are always the typical items we put modules on, so that, instead of the generator getting overloaded and kicking out and having to restart, the module kicks out the appliance temporarily, and allows you to adjust what you are using to accommodate your situation. If you are going to go to the extent of expense of changing your oven and dryer to propane or gas, then a less expensive alternative for emergency power is A generator. I personally like Generac. I installed 100's of them over 4 years, and it's a good reliable source of power. I'm not sure of the cost now, but then a 20kw or 22kw, the most common for whole house, was around 10,000. It can operate on LP or gas, and installing some soft starters, especially on older AC units that have a high start up surge, can help the system handle it. A 22kw is capable of handling multiple appliances at once along with heat and air and cooking. As long as you don't install the unit by a bedroom wall, chances are you will hardly hear it while inside the house, and you can sit it further from the house if you don't mind digging a ditch to run the wires to a transfer switch, which becomes the main disconnect for the house and is typically installed on the back side of the panel outside, next to the meter. because the service wire has to be rerouted through the transfer switch and then feed the house panel from there. It may sound hard, but it is a lot less work that the PV system and truly gives you more power and flexibility. It makes no sense to do the PV system and then make major changes to your heat and air and dryer and oven. The cost of this had to of been over 20 grand, and a generator install is not only more convenient and more powerful but less expensive, and there are options to manage large appliances with digital load modules, which are super easy to install, power in power out, and it communicates with the transfer switch remotely. Makes no sense to do what you're doing. If a person is wanting to be totally independent, then I get it. It is a great idea, but if you are changing major electric appliances to LP or gas, then I don't get it. If it is just emergency power you are concerned with, then a generator is a better option. If you want to be totally independent and run on solar for weeks and months, then P.V. systems are the way to go, or if you're so remote there is no power, P.V. systems are the way to go.

[@timstanley3585]

Nice setup. Thanks for sharing the load test. It was very informative for me. One suggestion for you or anybody else, if you haven’t already done it. Getting a heat pump water heater. The specs on those things look awesome. Home depot has a 50 gallon rheem for $1700. The energy guide says it uses 866 kwh a year. Plus you get a small amount of free ac from it. That would fit on your system and you wouldn’t have to use any propane on it.

Is your "solar room" climate controlled and if so how do you plan to cool it? Would this setup be OK in a regular Texas garage?

[@CountryLivingExperience]

Our solar room is open to the rest of the house as it is connected to our existing utility room. It is conditioned the same as the house. If by Texas garage you mean open air, then maybe. It may get too humid for the inverters and batteries in certain parts of Texas. Other areas may work.

[@Achilliez]

Good video, can I ask why you don’t have it hooked to the grid? I’m in Western Australia and I have a 6.6kw solar system and a powerwall 2, we use the batter as a backup but also to supply the house. It’s currently summertime so we make over 42kwh a day. But only use about 12-15kwh.

[@CountryLivingExperience]

Thank you. I want to be independent and unconnected from everything. If you are making that much power, you could sell back to the grid if your power company allows it and you want to be grid tied.

[@Achilliez]

@@CountryLivingExperience Thanks for the reply. Unfortunately, we have another 6.6kw system as we live on a farm and we are only allowed 1 if we want to sell back to the power company, i would only get $0/07c/kwh. I worked it out the other day the power company has made over $1000 AUD from the power we send back for free last year. I often think about going "off grid" but in wintertime we do have a lot of days where we only produce1-5kwh of power a day due to heavy rain and cloud cover. We have a gas stove top but not oven, it's helpful if thy power goes out so the battery can run the lights and water pump and other items. Anyway, thanks for the video its helpful, i like watching other people and how they set their systems up. Stay safe :)

[@sloup000]

[@Moist_yet_Crispy]

Heads up, if you're going to be using 100% solar then you need to set your inverters to Solar Priority, this will divert the dc power from the pv array to power you loads and partially skip the battery. The more you cycle your batteries the more they degrade. The batteries don't need to be pulled from during the day, so just use your pv to run your loads and the surplus will top off the batteries. That way you're only using your batteries during the night and dusk, will make them last much much longer. Love the vids btw

I rigged up our 2 chest freezers and 2 refrigerators on a circuit connected to one of my two inverters (both inverters on separate batteries and separate 120 circuits). If that inverter should lose output I have a contactor such that it automatically switches to the other inverter to provide redundancy for those critical loads. Otherwise the inveters are not tied together in any way.

[@CountryLivingExperience]

Interesting setup. Glad it works for you.

[@nikolaskallianiotis8622]

You said that you don't wanna feedback power to the grid but as far as I know, these kind of inverters (Off-Grid) doesn't feed back power from the batteries or PV to the grid. They can get input from the Grid to support loads in their output but not via versa. Can you elaborate on that ?

[@CountryLivingExperience]

Feedback to the grid in terms of a grid down situation. Just like a generator. I do not want to injure a lineman working to restore grid power by back feeding my solar/battery power into the grid. It will do this if my main house breaker and my solar breaker were on at the same time. That is why I put the interlock kit.

I'm excited to see how it works when I get it completed. I will not be back feeding the grid, as I understand that can't be done with GW off grid inverters. It will only be an assist if the PV and batteries are not producing. Thanks for all your video's, they have been a BIG help.

[@CountryLivingExperience]

Glad we could help. As far as I understand, this is what the internal set point is. I didn't change any setting to achieve that. When I use the term backfeed, I am talking in a sense of the grid being down and the main grid breaker being on. If this is the case, my solar would backfeed into the grid and injure a line worker. This is the same thing that happens when you have a generator in use. That is why I purchased the generator interlock kit and installed it on the main panel. My system is manually switched in the event of a grid down situation. Sounds like you have a big system. Good luck with getting it all set up.

When you say the system won't handle the heat pump, is it the amount of batteries you have or is it the Growatt inverters that can't handle it. Great video thanks for posting

[@CountryLivingExperience]

The inverters don't have the ability in terms of amperage. The 3 ton heat pump is too large and needs a lot of amps on startup. You can add a soft-start to alleviate that issue but our system is too old to spend that money. We are just going to add mini-splits.

Great video, I'd love to have a setup like this but with the solar being the primary source of power then the grid and a generator behind an ATS. Would it be possible to have the generator recharge the batteries?

[@CountryLivingExperience]

Thank you. Yes, you can use a generator to charge but it needs to be a very large unit. You need to be able to power your house loads and charge the batts at the same time. To get clean power (pure sine wave) from the generator you need to not run it more than 60% capacity. If you don't get a perfect sine wave charge, you will damage the inverters. Signature Solar has a good video explaining this.

[@joehenthompson2023]

Love your content but I must say that going to propane with your stove and dryer is going in the wrong direction. Since your system can operate those appliances as is, you are more “off grid” by having electric appliances that you can power with energy that you produce. I personally will be looking to go with a heat pump dryer, heat pump water heater and an electric stove with induction cooktop.

[@CountryLivingExperience]

Thank you. I understand that but I like to have redundant systems. I already have a full 1000gal propane tank. In an extended emergency time period, I can trickle that 1000 gallons for an estimated 3 years for just the stove. I will keep the electric appliances for backup as well. I am actually going to switch my thinking on the water heater and go with a heat pump as their efficiency has gotten much better.

[@chadcarrington1218]

Sometime this year Rheem is coming out with a 120 volt heat pump water heater. Hopefully it will be cheaper and more efficient than the 240 volt models. Might want to wait to see those reviews on them.

@chad carrington Thanks for the heads up on the Rheem

[@uhjyuff2095]

I agree, the stove, oven, dryer, microwave, are not super high energy appliances. Like he said he can trickle his propane tank for 3 years with those appliances, so why not keep them electric. However, the mini split idea is a great one, so if I had to choose, mini split or the other microwave and oven on electric I would 100 percent choose the mini split. The Mini split is the real high draw energy appliance, and number two is the hot water heater for most houses.

[@chuck1011212]

@@chadcarrington1218 Good point Chad, but I think for this system he would actually prefer to use a 220V heat pump water heater. This is for two reasons. 1. He has the 220V wiring in place already for his existing water heater, so no need to prefer 110V for easy wiring. 110V hybrid units are ideal for situations such as replacing a gas system with electric and not needing to run the 220V wiring. 2. The way these Growatt inverters are set up, they are 220V output and he has a step down transformer for serving his 110V loads. This gives him a desire to run 220V loads over 110V loads in his house to avoid overloading the step down transformer where possible.

[@Rev22-21]

Just an observation: More than likely the reason for the differences between the two inverters and their 'display usage readings' is commonly called an "imbalanced load". This phenomenon is commonly due to one or more 120Vac load lines drawing a bit more or less power than the other. Usually it's not a major concern unless the percentage differences are considerable. What percentage would that be? That depends on who one ask and (in this case) the inverter &/ or auto transformer company recommend. Correcting this issue sometimes is like herding cats, and other times simply turning off appliances.

[@CountryLivingExperience]

Yep. It is always an issue trying to track down the cause.

Great videos. We are buying our homestead here in Spain and I have been honing my solar skills with an existing grid tie system and a seperate Ecoflow DP. I have been chewing over the 5000ES for a while and I just cannot find answers to a couple of questions I hope you can help with. With funds being tight I dont want go down the wrong path and invest in non expandable system Do the parallel inverters seemlessly handle load balancing on the system? I presume they do as what would be the point of an expandable parallel system right :) And, if an inverter goes offline eg dies or is powered off, do the other(s) continue without issue, does a slave promote itself to master possibly? thanks in advance, any help/advice is appreciated

[@CountryLivingExperience]

Thank you. They balance the loads well between them but the Master inverter always handles a little more. Yes, the slave should promote itself it the original Master has a shutdown issue. There may even be a setting for that but you need to check the manual. I did have an issue with my master not waking up from standby in the morning (needed a firmware update) and the slave took over.

Cool video. I've got 3 of the same batteries you do and a sol-ark 12k. I almost went the growatt route but honestly after using the sol-ark I think I made the right choice. How long can you power your house with the 5 batteries? I can go about 5 hours with my 3 but that's powering the entire house including our 5 ton geothermal hvac and 2 50 gallon hybrid water heaters. BTW, if you haven't checked into hybrid water heaters, I highly recommend it. They take about 800 ish watts in hybrid/efficiency mode.

[@bills.4573]

As others have said there's really no reason to switch out electric appliances for those running on propane. In particular gas dryers are less reliable than electric. Instead, if you are in a cold climate switch out your air handler for one than has a propane furnace as backup instead of electric heat strips...then even with an extended loss of grid power your off-grid system only needs to run the thermostat and blower fan for heat. Which is what we do here, though with natural gas instead...natural gas is so cheap I don't run the heat pump in the winter anymore to reduce wear & tear on the compressor, which we really need for A/C in the summer.

It looks like you have not done this as the grounding screws on the left side of the pack aren't attached to anything. Is there a reason you didn't ground them? This is asked out of curiosity because if they don't really need to be ground it avoids the extra work.

I am still working on and experimenting with certain aspects of my system so in certain videos things may not look done.

I am trying to go completely off grid as well but will still need generator from time to time, is that what you meant by charging with AC? The generator will work fine? Getting mixed messages on Google, thought I might have to get EG4 Chargeverter.

[@CountryLivingExperience]

Cool. No, I meant charging directly from the grid on the AC IN terminals but that would be the same as using a generator for AC IN. You can use the generator if it is large enough. I think I mentioned in the Chargeverter video that you need to have a power superiority for the generator over the loads and the generator has a pure sine wave at 60 to 70%. So if you have 8kW in loads and you are putting 5kW into the batteries then you need 13kW but the generator would need to be at least a 21kW (61%). Some new inverter generators may negate this but I don't know much about them.

When I use the term "Back Feed", I am talking about if the grid is down. If you had your system on it will send power back through the grid lines and may harm a line worker.

Yes, correct. If you trip the overload protection on the inverters, you will just have to restart. Then don't start that combination of loads again. If you are putting in your own system, a homeowner should know the wattage and amperage of all his loads for smooth operation. The only way to avoid that situation is to buy a much larger solar system.

How much does this kind of system run?

We did an entire video with cost breakdown here......kzbin.info/www/bejne/rJ_KXnZ3eLWirZI

If I had like 4-5 inverters and 60kwh (gyll batteries), would it be enough to power a house with a Mr cool universal w/vrf central heat pump system for like a couple days off grid?

[@CountryLivingExperience]

Absolutely! That is a big system.

[@jamesshomesolarmore2223]

I have 5 mr cool mini splits. I also have 12000 watts of solar and 3 of the same inverter’s with the transformer. I have been running it on only 19 kw of battery storage. Using a little grid power. Tomorrow I get 4 more batteries and hope to have them hooked up by Wednesday.

[@uhjyuff2095]

if you have enough solar panels you can run it unlimited days!

[@CountryLivingExperience]

@@uhjyuff2095 If you have enough money you can do anything.

hi Is it normal for battery going from 90% to 100% within 5min? It's gradually charging from 30% to 90% and all of a sudden it goes to 100%

[@CountryLivingExperience]

That is a large jump in that amount of time. I have not had that experience. I would talk to the company your purchased from.

[@jasper9890]

It bugs me the time/date is so off on my EG4 battery but I don’t have a windows computer handy to try to update or configure it :( lol. I noticed the 2047 year on yours

[@CountryLivingExperience]

Doesn't bother me much. At least there is a sticker on each one telling me the manufacture date.

[@danielblack7977]

I was fascinated to learn you can't run your AC. Is it a minisplit?

[@CountryLivingExperience]

No, it is a 3 ton central heat pump. I do not have mini-spits. I am installing them soon so that I can run them from the solar system.

[@danielblack7977]

@@CountryLivingExperience Ah okay, thanks.

[@bloodcarver913]

That comment about the grid inlet...is wrong. Both inverters have an AC input. Nothing difficult about this. Run the AC grid input that you usually feed into the main breaker in the house panel into a small fuse box with overvolt protection near the inverters - then from it to each inverter and then let each inverters AC outlet feed the house panel together. Very easy.

[@CountryLivingExperience]

No it is not wrong. These are 240v inverters. There are some grounding and bonding complications. Please refer to Signature Solar's electrical wiring diagram for these specific inverters.

[@JamesLee-ey2yv]

Where can anybody find a wiring diagram from Signature solar or anywhere else that shows how to wire the AC in on the growatt. When I asked them how to do it they said repeatedly DIY,DIY,DIY. I've asked on almost every forum site discussing wiring and got "0" replies on how to do it, so I figured it out myself. I added 2 electrical panels. One I call my Solar panel with 4 - 50A for GW AC out, 2 - 25A for 2 Split phase transformers and 1 - 125A that feeds my house panel by back feeding a 125A breaker that has a Generator interlock to separate from 125A main grid power. My 3rd panel I call the Grid main panel has a 200A main from the grid that feeds the 125A in the House panel from a 125A breaker, 4 - 50A that feed the 4 GW AC in's and a 20A for my EMP protection. If it doesn't blow up, I'll have quite a story to tell. As always, any input is appreciated.

[@CountryLivingExperience]

The 5k growatt has a diagram on the website.

[@bloodcarver913]

@@JamesLee-ey2yv The manual that comes with the units from the factory show the AC in connection both in single and parallel hookups. It is also downloadable from Growatt as a .PDF

[@bloodcarver913]

@@CountryLivingExperience I have 3 of these in a 3-phase parallel setup as per the factory and had NO problem whatsoever connecting my grid in into the 3 boxes. I just took the grid input cables into 4P fuses and from there fed the inverters. The outs from the inverters to my main panel (no need for smaller panels as the 3 delivers 5KW each into each phase) via another 4P fuse for security. As these inverters do not deliver power back to the grid there is also no need for any interlock etc. Grounding is easy, using the same grounding as the house had from before with copper in the ground outside the walls on ONE POINT, not multiple grounds as that would introduce problems.
