Go Power Solar Controller Panel on Flagstaff E Pro

My new E Pro 19FD came with solar panel on roof and digital controller mounted on wall inside unit. The controller provides read out on battery voltage, amps provided from roof top solar panel and percent of battery charge. I have 2 ...12 volt batteries....and as I recall a fully charged 12 volt system should be around 12.6 or so....volts. My voltage readout is around 13.6...not 12.6....and percent charge is 90%....which should be 100% as I have been plugged into shore power.
When the unit was outside...in full sun the amp readout...from solar was around 4.5...which seems correct as I understand my 1 rooftop panel can provide around 5 volts in full sun.

Anyone getting similar readouts from the controller panel?

Disconnect the solar panels and let the batteries rest for a bit and then take a reading. The 13.6 simply indicates they are currently being charged.
Ignore the onboard meters. Use a good voltmeter.

See post #5 here for volts vs charge:

As carlsbad said, needs to be a resting battery.

Your system is working fine... As already said, 13.6v is indicating your batteries are charging.
12.7-8 standing volts would be 100%. At 13.6 charging it would be correct at about 90%.

Our stock converter charger never gets the batteries to a full SOC. Our solar does a great job of topping them off. We will be upgrading the charger in the near future.
