Hi, i have 4x100w rigid panels in parallel on my boat roof and this system has been working well with a pv logic 15amp mppt controller, however it wasnt making full use of the available power so i upgrade to an epever DR3210N 30AMP mppt...
I dont think it works correctly as the panels are always reading 22v which is the voc, the current being pulled is only 3amps (if i refit the old one its pegged at 15amp immediately and the panel voltage is around 16-18v).
It seems it is not tracking the voltage and instead just letting the panels deliver at max volts, and also the amps on the display are wildly innacurate upto 3 times the actual.
This is the second controller as i returned the first thinking it was faulty...
Any ideas anyone im out of ideas and tempted to buy something else if it wasnt for the good reviews.
