ALL, My setup is as followed: Growatt 5000 ES, with a split phase transformer. 2x 5kw EG4 batteries. We are completely off grid and have a Honda i2200 generator. My question is two fold: has anyone had any luck with using the generator as the AC input to the growatt? If so, does this charge...

All, We have an off grid cabin with an Growatt ES 5000 and 2x 5kw server rack batteries. (EG4). We leave this cabin intermittently and don't check our growatt. What settings for our growatt should be enabled so that when the sun hits the panels, the growatt turns on, charges the batteries, and...

All, See attached proposed diagram for connecting Heating pad for my Lithium phosphate batteries I bought at 48v to 12v step down converter, it comes with a 20 amp fuse connected to the 48v hot side. We already have 2x 48v batteries but our problem is that they get very cold during the winter...

Hi all, Running into some battery issues with our current set up Growatt 5000 es, 1x G4LL LiFePOWER 4 battery (Runs great) (this battery but no LED screen) (Picture Battery A) 1x LiFe POWER4 battery - Running into issues Link (Battery B) Issues with the Eg4 battery include: Unbalanced...

I've looked through a lot of forms, but I cant seem to find any that give a tank heating pad with low temp cut off option. They have all been 45F on and 68F OFF. Which is way to conservative. Are there ones that go on at 35F and off at 45F? i found one but thats from battle born and its $200+...

We tend to have snowstorms in the early months of December and November, and we are sometimes not there for weeks at a time to wipe the snow off our new system. Our roof pitch is 33 degrees, but I wanted to know after a big snowstorm how long does it take for snow to melt off panels? I've been...

So i wanted to get some opinion on setting up a separate system, 100W panel with a small battery that would run a heating pad for our Bigger 5KW LiFePO4 battery. Our specs (48V 5.12KW LIFePO4 battery from signature solar, 48V growatt 5000es, and 4S2P, 2,280 Watt solar array) We currently have...

Question: We hooked out our battery, growatt, and panels and had the Battery sending power to our Loads through the growatt. Unfortunately we had a cloudy day but our panels were getting Some light and sending a few volts to the growatt (measured with volt meter). My question is as followed...

I cant seem to figure out the wiring set up for 8 panels in a 2S 4P configuration. Can someone link a picture or diagram? I need to calculate how many 2-way and 4-way MC4 Connectors I need.

So I am doing calcs with a Growatt 3000W 24v inverter. and 2x 6.0kw batteries (240AH - 6KWH). I could use some feedback on my calcs/array setup. 15x 290W suntech Panels Configuration 3s5P. So the grow watt should handle up to 145Volts. Max solar charge current for growatt says 80Amps. Is...

Right now, we are in our planning phase and we realized that the Well pump we ordered: 5 GPM Well pump takes a TON of wattage to run (240 V @ 11.2 amps= 2640 watt/hr) Right now in our calcs, we have a 26 gallon pressure tank that would be depleted most days. (25-50 Gallons per day, 2 refills...

I am sizing my system and wiring some outlets in my cabin. All wires will go to my breaker, and the breaker is connected to my inverter. My question I have is when the breaker is on for some plug in outlets, will there be power loss through the wires if there is no load connected? or if there...

We plan to buy this LiFePO4 battery and store it in a shed outside (somewhat insulated). Only problem is that temps can get down to low 15s outside and low30s/High20s in the structure when we dont have the heat running. I would normally buy a heating pad but these batteries are incased in thier...
