This is my first solar installation. Six 150 Watt panels are connected in parallel to a Victron MPPT 100v/50a controller. Ambient temperature is about 75F. I would appreciate any feedback on why the controller’s output cyclically fades away. Is it overheating? The box only shows a steady blue Bulk LED. After the third cycle I pointed a fan at the controller and it seemed to make a slight difference In the duration. Is a cooling fan a common addition to these systems?
Thanks
Thanks
