I'm not sure if this would fit your needs, but I'm running a growatt 24v 3000w hybrid inverter with two 24v eg4 lifepo4 batteries. I am able to run my jet pump without any issues. Also runs my entire cabin with basic lights, outlets, a lcd tv and dvd player. It has also run my wife's 1500w hair...

My wife is getting jealous with all the time I spend looking at my charge controller when I hear the fan humming!😄

It would be cheaper to run a subpanel from your house grid power into the shack if it's near the house. Then you can run everything you want with out issues.

I guess I didn’t trust the growatt. I also bring the batteries home in the winter and wanted to option to charge at home with my grid ac. I leave the growatt at the cabin year around. Still figuring it out and probably making mistakes along the way. I just bought the cabin this season so over...

I just installed this unit at my cabin. Runs great with very little battery consumption and only when hot water is needed. Runs off a 20lb propane tank as well. So happy with in so far.

Thanks for all the background on this topic. Just to clarify one point. I am running two 24v batteries in parallel so I think I actually have 400ah and about 10kwh total. The pump wouldn’t start with just the one battery so I had to double the capacity. Hope this is helpful.

Thank you so much for the information. I got two 400a Pike busbars. Also included fuses as well. These should be more than enough for my typical usage, and are rated above even my maximum output.

I had a good experience from Signature Solar especially with communication about my order. It was a fairly small order relative to the OP, but Dustin treated me well and always responded to my questions via email within 1 day. The one issue I had is that only a partial order was shipped without...

It was a weird occurrence for sure. I think the change in sun angle and the location of my panels may have been to blame. I'm moving the panels to a spot further away from the cabin, that gets unobstructed sun regardless of time of year. My concern is preventing damaged batteries. I did have a...

I had time to head to the cabin last week. The Honda EU2000i generator charged the batteries perfectly connected to the AC in on the Growatt. I used 10AWG wire with no issues. Charged at 30A and in 4 hours went from 47% to 85% on my 10 kwh lifepower batteries. I'm very happy with the extra piece...

I have also seen I can use a dc power supply to "wakeup" the batteries and allow the charger to start charging. I have a 30V 5A power supply I could use to do this if needed. I'll also check the batteries voltage disconnected from everything with my multimeter once I get home from work this...

My 1/2 hp pump works with my growatt 3000w 24v inverter. I needed two 24v lifepower4 batteries to get the voltage it wanted to start up. With a single battery it would fault with a low voltage warning at start up. It has run fine since adding the second battery. It's my biggest load in a small...

I use this one. It has worked great for me. https://signaturesolar.com/eg4-battery-charger-24v-30a/

I changed my panels from series to parallel strings originally to avoid frying my AIO inverter charge controller as the temps got close to freezing in the fall. I realized the additional benefit when my production jumped way up even on partly cloudy days. Partial shading was killing my output...

I have a very small system in upstate NY that currently consists of three 375W solar panels (have a fourth but don't really need it), two 24v EG4 Lifepower batteries in parallel and a Growatt 24v 3000w inverter all in one. My cabin is off grid and is used on weekends year-round and occasionally...

Hi Ben. I charged the batteries fully and used them this past weekend. This seems to have improved the BMS performance as the batteries were showing a 26.3 voltage and a 44% SOC when we left for the weekend. This seems more in line with what is expected. I do have one question about the eg4 30A...

I have two EG4 Lifepower4 batteries connected to a Growatt 24v hybrid inverter. I've never pre-charged anything and was told the batteries have a pre-charge resistor integrated in. So far so good, as long as I turn on the DC breaker between the batteries and the inverter/SCC first.

Thanks for the helpful information!

I'm not sure if my generator is "clean" or not. It's a Honda eu2200i inverter generator.

This is how mine is set up. My batteries discharge equally and have maintained good balance when tested using the BMS software from Signature Solar.

Yes that's my model. I'll create a 10awg cord and try that. Thanks for the help. I'll be up there after Christmas and give an update once I try it.

I don't have any tracking programs running. I can say it's usually 30% of my total, so about 3kwh in the winter. In the summer it seems less due to extra light and great solar charging of the battery all day.

What type if battery are you using? How are you determining the state of charge? It may be off for a bit as your BMS recalibrates.

It’s also a 1/2 hp pump. I’m full of bad info this evening. I guess looking at the specs before I post is a good idea.

I have an off grid cabin that has a pretty simple set up that has served us well in the 2 years we have used it. I have about 1500 watts of panels feeding into a Growatt 24v 3000w inverter all in one . I also have two Lifepower4 24v batteries for storage. I run led lights, a small...

I would have gone with 48v if the batteries were available at the time. They were backordered and i went with the system I could get immediately. Has worked out fine, but would like the ability to add more input if needed.

My two 24v Lifepower 4 batteries are constantly giving unreliable percentage of charge due to my inconsistent usage as a weekend warrior at the cabin. I use the voltage as a more accurate indicator of SOC, but and hope that my Growatt AIO does as well. Last week end the Growatt told me that the...

That's great news. The article seemed very dramatic. It could be that price drops are a result of efficiency and cost reductions in production. I remain optimistic. The real good news would be related to somehow increasing the energy density of LFP batteries.

No, I have it shut down when not there in the winter. I run the generator for a few hours before we leave after a weekend stay to make sure we arrive with enough power for our next visit. It usually gets to 75% SOC and I have two 24v EG4 batteries in parallel at 5.1kwh each. In the summer, I let...
