Setup:
Multiplus II 48 5000, Cerbo, Fronius 501 @ ACOut, no feed in,
Settings:
Fronius: - set to MG50,
Multiplus II:
* programmable relay and general flag assistants are used to ignore AC In1 if SOC >50% not ignore if SOC <30%;
* PV inverter support at last position in assistant list.
Fronius is connected via WIFI to Cerbo and it looks as it should.
Behavior:
Cerbo is showing: Fronius 350W, AC Load 105W.
The issue is that the battery state changes from charging with 900W to discharging with 700W couple of times per second. BMS shows similar values.
In this stage ESS assistant is not an option.
Somebody has this issue before, is there a fix for it ?
