I installed my own controller and panels. Wires are the following
Red and back to roof ( No Voltage) Back and Red to breaker in Generator bay top drivers side 50A breaker. The wires are not connected both have wire nuts.
Cut hole, pull up wires, the voltage set goes to the battery of the controller the other will go to the roof. Panels plug in to roof top. Total time about 4 hours
