Update after 1 year of use off grid, Growatt and EG4 (Gyll) batteries

How is everything holding up after 1 year of use? What is the battery SOH State of Health? How many times have the inverters shut down? Overloaded? Nuisance tripped?
I've been running my Growatt inverters and Lithium batteries off grid for one year. They have been working great. In the video I describe pros and cons after one year of use.
The inverters are model 5000ES and purchased from Signature Solar. I have two in parallel for a total of 10kW of inverting capacity.
The batteries are Lithium, LiFePO4. Each battery is 5.12kWh of capacity in a server rack design. This mean my battery bank is just over 30kWh! My battery brand is Gyll, but that has been re-branded EG4 and is sold by Signature Solar.

[@CNile-se9xw]

Even mains powered electrical system drop voltage with a high surge instantaneous load, so the flicker is definitely not a problem. Regarding the fan noise, it might be helpful to remove the standard fans & duct larger fans through the units, or supplement the originals with a cheap external pedestal fan so they won't need to work as hard. 👍 BTW, I love the system that you've put together mate & would love to do the same, but unfortunately everything's either super expensive or unavailable here in Australia.

[@captainobvious9188]

I’ve noticed even putting all your circuits behind an inverter in grid pass through (with 6 AWG wire in my case) limits surge current enough to cause the split second light dims. It made me start noticing it in other older homes that are pure grid too.

There are tons of install videos, but very few after a long time, showing how the system has performed. Thanks!

[@DeekJohnson]

I installed the 24v growatt in RV trailer. The on grid off grid switching from battery to shore power and back again was flawless. The entire trailer was 100% live 100% of the time. Set Growatt to use AC shore power first, then batteries if not detected to power trailer. I removed my tv from the televator and mounted the Growatt on to the televator. Could not hear fans. Way more quite then this model. Installed my batteries back there too. Upgrading trailers now and need to upgrade inverter. Would mount this in heated pass through now. Betting I would not hear fans, unless they’ve upgraded them since this video. Great review

[@fredturk6447]

My experience is after about 4 years the Growatt inverter went faulty only partly working. I then installed a replacement Fronius inverter. That unit has been running with no issues for over five years. In other words getting a quality inverter is important. Maybe by now Growatt has improved, but be careful. Solar systems are about the long term and if your system is made of poor quality components it won’t last and won’t payback the initial investment.

[@richd9771]

@@piterex7 Hello......I have twelve- 24v batteries with 2 each in series to create one 48v. So that would be six and then I have two- 48v batteries for a total of eight 48v batteries. I wasnt aware of the single 48v batteries until I had already bought the 24v ones. When I built my system I wasnt sure what I would need so I bought a few then kept adding. In the future if I need more batteries Ill buy the 48v ones. Idea for your cabin...I always like to plan for a little more than I think Ill need. You may want to add more lighting outside or add something else...I would go with 2 Growatts just so I could have split phase capability and know you can power anything needed for your cabin. The good thing about these is you can add as you go, so start small and if there is a need for more than just add. Make sure when you wire up your system that its setup in a way so that you can add another Growatt if needed. I had to re wire my system a bunch of times because of that. I have a large house with my work shed out back and two kids that like to turn everything on so we use a decent amount of power. I get about 5 hours of power per battery but the more batteries add that number seems to grow. Let me know if there is anything more I can help you with.

[@joebass5163]

Nice setup. I found a used whirlpool heat pump dryer for $50. The lady said it wouldn't dry anymore and probably needed a disassemble and thorough cleaning of the coil. I was able to clean it without too much trouble and it draws around 1000 watts on a 240 volt circuit. I still have my conventional electric dryer and it draws 6000 watts.

[@DavidPozEnergy]

[@stldigitalmemories]

What did your setup cost???

[@atomp153]

I'm curious on the total cost as well. Are you running a big AC?

[@christianbecker4048]

All components from Signature solar came in around $62k for the batteries, battery racks, inverters, panels, and most of the wiring etc for the solar part. Another $4k for solar racking made out of wood (treated lumber) similar to what they have on the signature solar website As a sample with concrete footings. I paid $3k for electrical engineering plans just in case to double check and make sure my design was solid. Wiring and bus bars and additions fuse boxes and fuses for everything was expensive (huge wire gauges between battery bank components etc) maybe another $3k. I also bought a 20kw Cummins propane backup generator that runs through 3 more inverters to charge the bank if needed. So I have my 6 inverters in parallel handling my 96 panels (6 strings of 16 x 395 w panels) for a total of 96 panels and nearly 38kw of solar, there will be losses and the inverters of 36kw (charge controller part of inverters) do fine. I have 30kw of inverter capacity to produce 240 a//c which is 125 amps. 2 auto-transformers which create the 120v for my main panel.

NO,you should NOT write those lies here< The motor would overheat and shut off or destroy itself>. look here *from quora* . . Can I connect a capacitor in parallel with the Mains of my air conditioner? Sure! Go for it! But what, pray tell, do you hope to accomplish by it? Best case: the voltage rating is high enough and the capacitance value is low enough that nothing whatsoever happens. Next best: the voltage rating is too low, the cap self-destructs is a mild way, and nothing happens. More irritating case: the cap does not explode, but it’s value is high enough to draw current from the line, and the breaker trips. Yeah, well , that didn’t work so good. Don’t do it. Just don’t.

My system before being built out was a single and the classic 150 and it took me through Irma and Maria. I came online August 2017 and I am grateful I have this unit, I had running water, light and refrigeration. The island of St. Thomas was struck Sept 6, 2017 and two weeks later Maria, utility power was not restored to my house until January 8, 2018!

Thank you David for sharing your experience. One thing I want to share with you is about flicker at starting heavy load this issue because the sine wave of Voltage and the sine wave of Current is not a same at this moment you started your heavy load you can test it by using oscilloscope at output from inverter.

I am running four of these in parallel with a single auto transformer for my entire house and it's a great setup. Since I have four in parallel, the load is split among all four and the most I have seen is 20% per inverter with my AC running. Due to the low duty, the fans are not as much an issue as I thought they would be. As for con #2, I have the same issue, when the AC compressor starts, some of the LED lights in the house blink just enough to notice them, but not enough to kill any electronics running in the house. Some older LED bulbs I have don't blink, but I noticed those also fade off when turned off as opposed to the newer LEDs which are a decisive off as soon as you turn them off.

I've considered making one for years, but I find it hard to justify because I have a natural gas utility.

[@DavidPozEnergy]

The solar thermal has been running fine. I've never had to do anything. The automatic controller turns on the pump when the sun is available and it's just that simple. However, I would not do it the same way again. These days I'd probably have a 100 Gallon electric tank with the bottom element connected as a diversion load when the batteries get full. I'd rather use the roof/wall space for solar PV (electric) panels.

No issues other than occasionally the wifi loggers will drop out recording data for a few hours. Only ever overloaded them once and they came right back up automatically after. Only downside is they don't support very high MPPT string voltage. Looking to add one of these ES inverters dedicated to my 240 volt loads though I see they are out of stock right now. I have a heat pump dryer arriving on Monday that will eliminate my last gas appliance after which I will have the utility company cut off the gas so I can stop paying the base fees for it and run everything off of solar.

@@aboveallthingslove6349 Simple solution that I'm sure you could find searching KZbin versus me trying to explain it. Two wires and you're done.

[@tirivaenim]

Areas I’m curious on are: • Your panels, quantity & their size; • Why did you use an external (Victron) charge controller; • What’s been total investment cost & expected return on your investment?

[@DavidPozEnergy]

The panels are a mix of ones I bought used on Craigslist, but the total is 12kW I have 3 arrays, each array needs 1 charge controller I don't know, probably something around $15-$20k, but it's been over so many years I've lost track.

[@tirivaenim]

@@DavidPozEnergy but with 3 strings of panels, would each have worked going into the built-in MPPT of each inverter, or reconfiguring your strings to still fit into the 2 inverters or is your VOC too high. Am just trying to figure out why you use an external MPPT, Victron being expensive as it is, but being good though.

[@DavidPozEnergy]

Max Voc of the Growatt charge controller is 450Vdc (if memory serves). The Voc of some of my panels are 47.7V. I have 7 in series per string. 2 strings in parallel per Growatt, which puts my Imp at 19A. The Growatts clip this to 18A. If I add more panels in series I'll be over the Voc (with temperature compensation) and if I add more in parallel the power would just get clipped. I had the Victron charge controller from my previous system so it didn't cost me anything more to use it.

@@DavidPozEnergy thanks for the speedy response. I’m in Africa where every cent counts, making the move to Solar uneconomic for the average household, yet we enjoy copious amounts of all year round sunshine in most parts of the continent. Lithium batteries are still not cheap enough nor quality inverters or MPPTs for the average home, sadly.

[@JbowlizzleKC]

@@DavidPozEnergyi thought the grow what inverters didn’t need extra charge controllers, they are built in?

Thank you for your great informative video, thank you😊

[@hivolco151]

Nice demo!

[@props-model-shop]

Even with a high powered Inverter Generator my Led Lights blink as well. Led Lights must be prone to blink no matter what is used..

[@LuisGonzalez-lm3mv]

Are the fans changeable, a couple of high efficiency noctua fans will make this system interesting

[@DavidPozEnergy]

That's a good idea. Do you happen to have a link to the type of fans you like?

[@AttilaAntal]

I have exactly the same setup but connected to the grid too. It is working seamlessly, the only con I discovered is when I restart the whole setup the 300 mA RCBO (that is protecting the input) is shutting down. The workaround for that is to start the inverters with a 5+ sec delay between. No regrets for the investment. Many thanks for your videos, cheers!

[@kelgadeke5102]

Hi, would you estimate what you have spent on setting up your system? Regards Kel.

[@AttilaAntal]

@@kelgadeke5102 Hi, I have 8.6 kWp project, mounted at south in 2 strings of 8 panels of 540w (so 16 in total). Each string has an inverter of 5 kw (Growatt 5000ES). The inverters are working in paralell so in theory they can provide 10 kWp. I have LiFePo rackable batteries in a nice rack (3 pieces of 48V/100A each, Nifeitor chinese stuff). It is totally off-grid and the grand total of cost (including the mounting system, cables, etc.) is 56000 RON that is around 11400 EUR.

[@glenmarsh1224]

Awesome review thanks

[@ssoffshore5111]

Now if I could only get Signature Solar to answer the phone or return calls, I think I'm on week two (or is it three?) waiting for them to return my calls. Too bad for them, I dropped over $10k with someone else this week after throwing in the towel!

[@gemrough]

I’m waiting on 2 orders from them… I think they must be swamped… I am also looking at ordering around another $10k worth of stuff… might not be from them if they don’t deliver soon!

[@porscheguy19]

If you've been using this exclusively without the grid, how has it been on extended cloudy days? Are you over-paneling the system? Have you had lean days where there hasn't been any sun for a few, and you have to ration the use of the stove and dryer?

[@DavidPozEnergy]

I have a manual transfer switch at the main panel. If my batteries run out, I can switch the house back onto the grid. When I do that the inverter system is completely disconnected. I did that just for filming this video so the fan noise wouldn't be distracting. There were a few days in February when I had to switch back to the grid, but it was pretty rare.

@@DavidPozEnergy do you heat your house with electric heat

[@gemrough]

Do these not have the settings where you can run SBU or SUB like the EG4’s?

[@DavidPozEnergy]

Hi Chuck B, Yes, my house is heated using electric. I was using the Mr.Cool Heat pump to heat my house, but it died last year so the past season I had to switch back to my baseboard. Right now I have a window AC in the house so I'm looking at getting a new heat pump for the house.

[@JMSobie]

Would that be the single electric baseboard in your crawlspace that you discovered heats the entire first floor?

[@brianlewis1659]

Thank you for the update. It is something my wife and I wondered about how they would hold up. We are building an off grid home stead in Wyoming. So if you have any more pointer’s let me know

[@DavidPozEnergy]

Insulate and air seal. I built my house 10 years ago with double stud, super insulation, etc. It makes all the difference. I can cool it all summer with a small window AC instead of needing some monster 5-ton unit. That keeps the Amps low, which means smaller inverter and more cost affective.
