Hi can any one point me in the right direction. I have 2 Acpert inverters master and slave .And 4 pylontech 3000 batteries my issue is the pylontechs are showing ( full row of green LEDs ) fully charged and the inverters are saying not fully charged  and every morning l get a error 4 low voltage.when batteries are still showing nearly fully charged. I cant seem to get to the bottom of it 

Thanks in advance 

Steve 

You possibly have default battery voltage settings, which are not suitable at all for Pylontechs. Try the below settings.

Thank you so much for taking the time to respond.will give them a tray later 

Hi sorry just a bit confused as the manual l have has setting no 2 is total charge solar and utility 

Thanks Steve

Yes, it's the maximum charge current allowed, solar and utility combined. You need to set this to a value suitable for your battery, so it never gets too much charge current. The setting is a maximum current in amps.

In your case with 4 US3000s, that would be 37 * 4 = 148 A, round down to 140 A, to be split over two inverters, so use 70 A each (or 80 and 60 if one of your inverters has more or better-oriented solar panels than the other).
