Hi to all,
I have a 2017 Grandby with the ZAMP 160W panel (factory installed). I extended it with two flexible 120W panels and ev was fine for about 1and1/2 years. Then one of the flexible panels failed and shortly after that the other. The max amps I had seen on the ZAMP charge controller display was 17amp. Now I am thinking of replacing the two faulty panels with another rigid one and remember stumbling over a post somewhere that the capacity of the solar wiring is limited. So I checked with FWC and aws told the system is limited to 200watts. ??????? That seems awful low to me as I read a lot of post of larger solar systems and don`t have the impresssion that everybody switched from the ZAMP PWM controller to a MPPT type and connect the panels in series instead of parallel.
Is there any expierience/knowledge out there how many amps I can safely run through my FWC solar wiring?
thanks for input
