My system uses a Multiplus 24/2000 inverter
Recently, there was a grid power loss while on solar.
After the grid power was restored I couldn't get VRM to change the M+ from "Inverter" to "On" (grid power).
So, what I did was to manually switch off the battery power to the M+ and then turn the battery power switch back on.
Once that was done I could control the M+ using VRM with no difficulty.
Perhaps the M+ setting that may be effecting this is "Solar and wind priority"?
Do you have any idea what M+ settings I should change so that I don't have to repeat process above?
