I hacked my water heater today before I read this thread. Its electric 4500watt elements. The top one comes on first, when it meets its setpoint it lets the lower have power to make its set point. I set the top to ~110 qnd the lower to 125. My timer is an intertec, ifound, it nneded a clock motor( $18 ). I put the timer in to interupt the lower elements normal cycle. It now only comes on when my solar pv panels should be producing. It is better to use than to sell. I have thoughts of putting lower powered elemnt in lower position. solar panels can barely hand an element.
I am retired so in the day time I try to do things that can use the solar power, and avoid night uses. I welcome suggestions and thoughts on my hack job.
