I've been trying out these settings, my 5000es was initially setup (not by the installer, so presumably by growatt) as 27 CAP = 5.0 (inverter capacity) 29 Grd.v = -0.8 (grid voltage offset?) 30 Bat.v = -0.1 (battery voltage offset?) 31 Inv.v = 0.0 (Inverter voltage offset?) 32 Out.v = 0.0 (Output voltage offset?) I have modified 30 to -0.1 to -0.4 and now the inverter and battery (voltmeter) both read the same voltage when not charging. I also modified 31 from 0 to -0.7 and now when charging from pv the voltages match. I think that I'm also charging the batteries at different voltage than before, but I cannot be certain of this. I'm not sure what 29 means, but I suspect it's the battery offset when charging from grid.
