I have an 11.0 kW 50 Hz generator connected to the AC1 input of a Quattro 5000VA.
When the generator is running I put the Quattro into charge-only mode per https://www.victronenergy.com/blog/2018/04/20/multiplus-quattro-inverter-chargers-improved-current-limits/ so I can pass power through the device directly from the generator.
Generally I am passing 2600-4000W of power through. This consumption is well within the available power from the generator and the Quattro.
However, when I do the above, the Quattro simply switches off completely.
The power consumers are air conditioners that do have a high locked rotor amperage but that too is well within the available power from the generator.
Why is the Quattro shutting down?
