CCGX relay to use the solar excess power

Hello

I have a 3 phase ESS installation, with a CCGX.

I use the ESS zero feed-in to ovoid exporting power back to the grid.

My question is : Could I use the CCGX relay to control a power contactor in order to use the excess solar power instead of limiting it?


Many thanks in advance

@Samir Where would you be using/sending the excess power? And yes the relay can be set up to signal a contactor for something else.

@Alexandra Thank you for your response

I'de like to use the excess power to heat water.

I intend to set up the system so that the excess energy will be used to power the water heater when battery is fullly charged. But I wonder if the solar power is not sufficient, the energy need will be taken from the grid.

Hi I would like to do exactly the same but i cannot find any way of using the PV Charger value to control the CCGX relay or indeed the Quattro relays. Have you found a way please??
