EG4 6500ex controller settings from 24v to 48v

[farjim]

I’m looking for some help with my controller settings. I’ve got a EG4 6500 ex 48v inverter and I originally had 4 12v AGM batteries but have just switched to 8 12v Li Time LifePo4 230 amp hours setup as a 48v , I’m not exactly sure what to set my charging and discharge settings on the inverter.

Oh, and make sure you top-balance all your batteries first, before connecting the series groups into a string (so all your batteries are matched SoC). Because if the series groups are not balanced they will always be out of balance.

Hope this helps..
