I want to turn on a 110v electric space heater when the sun is producing a certain amount of energy because I have solar panels. The "receiver" unit would be outside and the "Relay" unit would be by the space heater. There might be a unit like this on ebay but I don't now the name to search for as I'm a circuit novice or if not, then what components/circuit would I need to do this. I think I could use old small solar light feeding into a variable circuit (pot) that once the voltage was at a certain value, it would trigger a 110v relay on. I assume there would need to be a "bandwidth" so it wouldn't cycle on/off every few seconds.
I'm a circuit novice so if there is not a unit on ebay (what name would I search for) then what components/circuit would I need to do this.
Thanks for any help
