As per heading, I have 2 8kw Deye inverters in a parallel install.

My issue is there is a battery voltage discrepancy between the 2 inverters. Of between 0.1 and 0.2 volts.

I have redone all connections between battery and inverters twice, and when I measure the voltage manually at the inverter battery connections with a voltmeter they are equal.

This causes some weird issues, such as at end of charge one inverter keeps "charging" the batteries while the other "discharges" them.

I have also tested this without load and under high current draw, and the voltage difference stays very similar between the inverters.

Anyone know of a way to calibrate the inverter voltage as the issue seems to be that they are simply measuring different voltages.

Just bumping as I haven't been able to find anything online regarding this.

Any help would be appreciated.

 

Hi 

Did you ever solve the issue as I am currently sitting with a 0.5 difference and I believe this is causing some of my issues
