Does anyone know of a solution for regulating power based on excess solar production? I have systems setup already to turn switches on or off which is great but my hot water cylinder has a 3kw element in it that I know will happily take any power I send to it as its a resistive load.
So what I’m looking for is a way to take my X amount of excess solar and send it to the HWC, ie I want to throttle the power going to the element so it only ever uses Solar and never pulls from the grid.
I know there are commercial systems that do this but was wondering if anyone had an emonpi based solution they knew of? I don’t know enough about electrics to be able to build the hardware myself.
