Hybrid off grid frequency shifting

[Lucderveaux]

Hello, I am working in a hybrid off grid config, landcode 50. I had from time to time high voltage alarms and DC rimples alarms. I have a 10 kw MULTIplus 2 with victron Mppt 250/100, a Fronius primo, Cerbo and 2*12 kWh batteries with bms. Took some time to get the configs right. I builder a widget where you see the battery voltage, the frequency on the output of the MULTIplus and the power output of the Fronius. No alarms any more, battery stays on 98 procent as long as there is enough light to offset the load
