RE: 6000XP no solar, used as backup generator only, AC Charge will not work

@mylesj I think this is a good solution: It comes with a 240VAC power cord that should plug directly into a 240VAC generator. It will also run...

RE: 6000XP no solar, used as backup generator only, AC Charge will not work

@joel-brodeur Will the 6000 boot up and run on just battery power? I assume it will, just like the 18K... I scanned through the thread but don't ...

RE: 6000XP no solar, used as backup generator only, AC Charge will not work

@mylesj The flickering may be because your batteries are very low now. 45.9V in that video is about 5%. See the voltage chart I posted in a differe...

RE: 6000XP no solar, used as backup generator only, AC Charge will not work

@mylesj One more thing... your batteries are NOT at 55% SOC or anywhere close to it. They are near dead. 47.6V is less than 10% SOC. This is related...

RE: 6000XP no solar, used as backup generator only, AC Charge will not work

@joel-brodeur I looked at the manual... it appears that function is just incorporated into the single "AC Charge Based On" setting for the 6000. ...

RE: Another App problem

@pawnee Did you update the LCD version too? If not, I think that's the cause of the watts display problem.

RE: BMS not correct in detecting capacity

@twistedroutes Yes, that's a good point, and it illustrates that in the end each person needs to find good voltage set point values that are releva...

RE: BMS not correct in detecting capacity

@twistedroutes That looks like a significant discharge load - I estimate about 24 amps per wallmount battery from your graph. So these are not rest...

RE: Enough Batteries or Incorrect Setup

I think that's effectively what I do when I charge using the Chargeverter. It's set to charge at 56V, and I leave it running until all six batteries e...

RE: Enough Batteries or Incorrect Setup

@joel-brodeur I just started re-reading that thread from SS on recalibrating SOC. So many things wrong with these instructions. In what world is 46...

@in-offgrid-greenhouse Are you charging with the inverter? If so, are you using SOC set points or Voltage set points? My experience with inverter...

RE: Enough Batteries or Incorrect Setup

@in-offgrid-greenhouse Rather than numerous cycles, can you get one good full charge on the system to reset the SOC 100% reference point? How log h...

RE: Enough Batteries or Incorrect Setup

@in-offgrid-greenhouse OK, then I don't think you have a SOC drift problem - your baseline discharge current of ~6A is high enough to avoid it. F...
