WHAT I wanted to say was my solar produces higher voltage than the mains and I only want an output to my item plugged into I 13 amp socket when the voltage exceeds the mains voltage. Hope that is clear as I am 82 I'm not oh bright as I was.
I want an automatic switch that I can connect to my mains which will not conduct at normal mains voltage but will switch on when my solar is operating to give an output to a 13A socket. Does one exist?
