I have single MP-II 5k/48V configured in ESS mode.
Inverter is combined with:
- BMS for Lion batteries connected via CAN-Bus
- Venus-GX connected via VE-Bus
- Smart-meter connected via ModbusTCP at the grid side
- solar PVs are connected via AC-coupled (in parallel) with Fronius 3-phase inverter
All had been working great for weeks until the moment when I switched the inverter off using switch button at the bottom side of the device (II-0-I). Since then, device is in Passthru mode and I'm not able to make it to use batteries again.
There seems to be no way to take it out of that mode.
I tried Restarting all the components including MP-II, CCGX, smart-meter, BMS, etc. etc.
I tried to change different parameters in the configuration.. no help.
I searched for the errors and I could not find any specific except this one which appears short after CCGC is restarted (via menu):
Found in: Settings -> Services -> ModbusTCP
I read the ESS FAQ and I reapplied all checks and assumptions.. no help.
Any help would be appreciated.
Thank you
