Where did you get yours from? I never had a MPPT problem causing over charging, so no auto over charging voltage shut down here. Sounds like a good idea to have one if its affordable. MPPT input is around 80VDC, 2 panel strings. I'm thinking of using a voltage sensing relay to control the Kilovac, messing about with a Nano is too hard for me .
