Link Use it to control your Kilovac. I place a Kilovac or equivalent SSR on the PV inputs to each charge controller, then if a controller shorts and leads to an uncontrolled charge\over voltage situation the PV is isolated, ergo no charge. I might remove the DIY SSR's, if lightning hits nearby they could short also. Cheers Mike
