My panels and charge controller (400w Renogy panels with a Renogy 40a MPPT charge controller) were up and working fine. Then I buried the wire and the voltage was at zero so I think I probably pulled out the wires from the panels to the controller. When I took the wires out and reinserted them, I think I may have accidentally put the positive wire into the temperature control slot and the negative into the hole for the positive.
After rewiring it correctly, now my charge controller screen won't turn on at all even when connected to the battery. Is it possible that I fried my charge controller? What else do I check if the controller seems completely unresponsive? Thanks.
