I have 2 Epever 40 amp tracers panels are connected in series per controller (2x300w panels) charging a 400amp Lifpo4 battery bank.
Its cloudy today sometimes the sun comes out from behind the clouds but it seems when the light dims they will drop back from MPPT mode to PWM mode, once I disconnect them from the solar and reconnect them they go into MPPT mode giving 50% more energy but poorly as they are not hitting the peak VMP(around 60v) rather staying at the VOC (69v)
Am I missing something both controllers have the same behaviour.
