So I'm just doing dumb little test with my sun gold, I"m noticing almost a 2.5 volt difference between what the inverter is saying and what the batteries are, granted I'm using 4 x 4s lfp rc car batteries to get to 48v, but still this is concerning.

E.g. my batts are at 53.5v but the sun gold is reading 51.1v

This can cause an issue, I know magnum inverters have a gray remote sense wire, is there anything for these LV6548 style inverters to do something similar? What about inverter comms, if you have a battery with the canbus communication will send the correct voltage to the inverter?
 
Anyone?

Almost 2.5v difference between the batts and the inverter.. not very good, would communication with the inverter fix this issue?
