Had a heavy storm that knocked one of the solar panels over and had watering pooling near the wiring. The controller is alive running on battery power but the yellow LED is off and the power output is 0. I've tried disconnecting everything and reconnecting and no luck. Would a short of the solar panel connections permanently damage either the panels or the controller? Can I take a 12-24V power supply and connect it to the controller's panel terminals to determine if it works without the panels?
