I have two times 4 80 watts panels in series on my catamaran to charge the Li-Ion 48 volt system. Each serie is connected to a mppt 150/45 controller.
One side is working beautifully, the other side is not. When I swap MPPT the other side works as well
The MPPT which is not working gives bulk flashing when it is connected to the battery bank. When i connect the panels the PV output measures zero (when i do not connect the panels to the mppt, the panel voltage is 84 volts as expected)
The blue light continues to flash. I think I had blue and amber flashing when i first looked at it, but I am not able to replicate since i disconnected to try the panels on the other MPPT
Does this mean this MPPT is broken?
Is there a way to reset the MPPT?
I cannot find anything in the manual?
Both mppt’s are connected to the ccgx (color control) which is on-line
Thank you for your help
Kind regards
Rob Becker
