Cerbo GX dump load to hot water system

Hello, I have a 10kva Multi, Cerbo GX and 150/100 MPPT and a number Lifepo4 48v 200ah battery banks in an off grid system. I want to use the excess solar wasted after the SOC is close to 100%.

I have an electric water heater that I want to either power from the AC2 from the multi on its own or use a relay to power the heater from the existing house circuit and change the element to a 2.4kw.

Is it possible to set it up to dump power into the heater with either of the 2 methods above while the SOC is close to 100% and turn off that load when the SOC drops or the thermostat turns off?


regards


Jason

You can use Assistants in the multiplus to control the ac2 out or you could use the generator autostart feature on the gx unit to turn a relay on and off as per the gen start conditions- using the gx would be easyer I would think
