I installed an island, 3-phase system with 3 multiplus 2 48/3000, a 3-phase SMA 10.0 Tripower PV inverter and 2 pylontech us5000 batteries.
When the batteries load, the system works like a charm, but when they get to 100% there is always a full shutdown due to high voltage errors. I set all the charging voltages in several menus (victron connect and directly in the cerbo gx) to 50 V, so it should stop charging, but it always runs up to 54 V and then produces the error.
My suspicion is, that the frequency shifting for the inverter does not work as intended.
Any help is greatly appreciated.
