I have my PV Solar array up and working. Presently only have it preheating my Rads. Grid tied thermo switch fitted. Can anyone suggest a means to protect my small preheat water tank in the event of the grid or pump power failure.

I have a PRV fitted but I would like to extra protect and fit some sort of switch on the water tank or elsewhere to cut off the power from the panels in the event of power cut or the pump fails.   Thanks
