Compounding!:)

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

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.

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...

Can I get one? I have two Lifepower4 batteries.

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.

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...

I have a similar setup and situation. I've only had the cabin for a year and a half so far. The first year I used the system all summer and never turned it off. The batteries have no trouble keeping the charge at 90-100% even with a small fridge running. The first winter we didn't know what to...

I'll happily test out a unit:)

I have a 2021 Kona that has been a great intro into the EV world. I wanted a Model 3, but the hassle of getting one and the lack of reasonable repair options kept me away. The Kona is leased and I got the full EV credit as a result as a point of sale discount. The car is a bit on the small side...

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.

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.

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...

Thanks for the additional information. I have the manual at the cabin and I'll adjust those settings and see how it goes. I can't wait to try it and hopefully get this figured out. I appreciate the help!

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

It does work at home. When I connect the leads from the charger to the bus bar in my system the Growatt faults and alarms. Maybe a setting needs to be changed? Or do I need to disconnect the batteries from the Growatt to use that charger? I was hoping to have the inverter running while also...

I have a 24v Growatt AIO inverter/charger connected to two EG4 Lifepower4 batteries in parallel. I have no trouble keeping them charged up in the summer, but winter is another story. My cabin in only used occasionally in the winter months and the system is turned off while away due to the...

I own the Champion duel fuel. It's been great and I have been very happy with it's performance.

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.

Yes I have the fridge running as my only load when away. I'll check the SCC settings. I have never adjusted anything except the battery type.

The cabin actually stays pretty cool through the summer months without AC. I may just turn the PV off at times to let the batteries cycle down a bit while I'm there and fill up again in my absence.

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...

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...

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.

One more question. Do the wires from the PV panels need to go in the top of the shut off and continue to the charge controller from the bottom? Or does it not matter.

Thank you. I’ll do the continuity test first!

I need some help with the wiring of my IMO DC Disconnect Rooftop Isolator Switch. The paperwork it came with is not clear to me. I think the correct wiring method is to connect the wires in diagonal orientation on each end of the switch. Can someone that has experience with these confirm this. I...

This happened to me the one time I used the callback feature. Never got a call back. I called the next day and finally got through.

Each panel has a Voc of 48.1. They are 375w panels and I was running three of them in series. My AIO had a max rating of 145V so once my panels got in cooler weather and got more efficient, I was going to be in trouble. They now show about 38-40v in the string and Amps depends on the amount of...

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

My batteries do have temp protection in the BMS. The odd thing is that it disconnections the charge terminal at 24F and not 32F. Not sure why.

Thanks for the insight. I have left them at about 70% charged last time I was there. I'm planning a visit in mid February and will charge them up with my generator at that point once they are warmed up from the wood stove.

I have two EG4 24v LiFePo4 batteries at my cabin with the breakers in the off position. I just saw that the temperature is due to go down to -25 this weekend. Should I be concerned about them being damaged or are these fine at this temp as long as they are not in use. Temperatures this low are...
