Hi everyone

I have a GX inverter with a generator and i can’t control it by state of charge (SOC) because my inverter hasn’t the cerbo’s relays.

Is there any option to controll my generator start/stop by SOC?

I think I can only control it by voltage and power, like a normal Multiplus II.

Thanks
