PV solar system charging voltage low
Ok solar gurus - I am experiencing low voltage with my PV solar system. The charging voltage will not go above 12.8V. I'm using a Morningstar SS-6L-12V SunSaver controller (2nd gen) with 4 new Crown 6...

Measure the input voltage at the controller with a digital multimeter
If voltage is correct, measure resting voltage of batteries after sundown
Now connect to shore power or generator and charge for six hours
Now measure voltage during day time solar charging
I suspect you are trying to run on solar only, with only one 95w panel
While this is enough to help with a weekend, and maybe recovery while in storage
It is Not enough for extended camping without aux 120v for charging
