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...

we have a com cable that goes to the growatt, so there is a Comms between the BMS and growatt. but i see what your saying it only measures voltage at the end of the day. So you are suggesting, in setting 19, to raise it from the default 56.4 v to say 57 or 58v? and with setting 20, default to...

Could you explain this in more detail for me to understand? This might be a possibility when we show up to camp and we turn back on the growatt, our batteries are around 70%~ so maybe when they drop below say 50% the growatt on standby kicks back on during the day? I am going through the...

Okay then i think there is an issue with our growatt... we have been doing that but when we arrive back to our camp after having turned the growatt in standby mode; there is full sun but the growatt is dark and not charging the batteries. Must be something wrong with our growatt.

Does this happen when Power save mode is enabled?

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...

So i have a laundry list of questions for you. The panels at 70 degrees above horizontal, when you say the snow removal is easy, you mean, you manually have to go up there and clean. our issue is that no one is at our Cabin from Dec-Mid march and we are subject to snow storms, (not as bad as tug...

30 degrees from horizontal. actally its more like 26 degrees from our roof pitch. My uncle and i were going back and forth. He says we wouldnt have to clean off snow if we had the panels more vertical (70-90 degrees from horizontal.). I think that, even if we get them to 70 degrees or even 80...

Question, What angle do you have your solar panels at? from the image they look nearly vertical? Also with out getting into specifics, what region are you in?? we have 8 x 300 watt panels at 30 degrees in western NY. they are mounted on our roof. My uncle wants to create a steeper angle to...

question on this, the wire used to connect From the 48v bus bar to the 48v-12v converter... is there a certain gauge i need for the high voltage? The converter has 16 gage wire... My batteries to the bus bar to my growatt are all 2 AWG.... SO should i just stick with 16 Gage?

Wait so what do you mean by wiring a regular 120 volt AC heater elements? could you give an example? Is that like wiring a heating pad i would plug into my house, stripping the wires and then hooking it up directly to the Bus bar? Also, any recommendations to heaters/heating pads that aren't...

So something like this?? if so what type of amp Breaker? a 20 amp Breaker? or something bigger? it should only be 5 amps with the circuit.

SO with the snap disk, i am not sure how i would wire that or where to place that? It would have to be in our open battery box but the temp of the box could be lower that the actual batteries where the heating pads are attached.... again just not sure where i would wire it in so the heat would...

SO the heating pads Kick on at 45 degrees and kick off at 68 degrees. I may install an additional temperature on/off switch see below Switch that way They will default to this if the internal temperature module craps out

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...
