In a 3 phase system, when the inverters reject the incoming grid power, they now all switch to inverting mode. But because only 1 phase is really bad, I would like only that inverter to switch to inverting and the others can remain pass-through. So I switch off the "Switch as a group" option, but now I found that now I cannot run an ESS configuration on the system... :-(
Any ideas on how to have "Switch as a group" disabled and run a 3 phase system in a UPS style operation. (Backup for grid failure. To replace a diesel generator.) We also have DC-connected PV, via 2 * MPPT 250/60 and we want to feed back the excess PV power back into the grid when the battery is full.
