I used the MPPT sizing calculator and have some questions about the results. Here are my inputs using a custom module:
Wp: 175
1 series 2 parallel
Voc: 23.9
Isc: 9.5
Vmpp: 19.5
Impp: 8.89
System voltage 12.
When I enter this information the calculator recommended a SmartSolar 100/20 which is what I purchased. In reading the specs on the 100/20 and in looking at the output once it was installed I see it can only handle 280 watts at 12 volts. Is this undersized for my panels? Am I wasting 70 watts of input?
Thanks,
Chris
