Factory Solar Question
My factory 80W solar has never kept the battery charged when the camper sits for a couple of weeks. Not an issue now as I store it inside a hangar plugged in, but when I first got it and stored it in ...

Please, O please, someone point me to an 80 Watt solar panel that has a specification of 6 Amp output, as posted above. The best mono crystalline 80 Watt panel I can find can only output 4 Amps..... My Zamp 100W monocrystaline panels are only rated at 5.5 Amps.
Panels are built with higher voltage than 12v. Otherwise they wouldn't charge the battery.
Usually 18-19v. for 12v nominal panels. If the panel is 80 watts at 18v it should be around 4 amps. Thats coming from the panel, not what's going to the battery.
The charge controller must lower the voltage to the 13 or so volts which raises current (amps)
It what comes out of the solar charger that's important.
