Tried all the stuff and a cold reboot by installer fixed it. I did not pay attention 😐 Was changing parameters in PV today, but somewhere something went wrong (parameters were not saved, and the setting for DOD off-grid now also gone, probably because it is not connected). Anyway, want to do a cold boot, but want to make sure. Switch off 2 switches on DB next to inverter (main switch last, no need to switch leakage one off), then rotary switch under inverter to off, then wait a while, then reverse ie rotary switch to on, and then the DB switches. Is that correct? Thanks!
