The solar panel was to check off a standard feature.
It was meant to top off the chassis battery but it’s a joke.
The led on the front ac is supposed to light up when it’s charging.
I meant to mention on another post that those units are heat pumps that are reversible for heat. 
I don’t think I mentioned that the genset coolant needs changed too. It’s tricky so ask for advice when the time comes. Extended life of course.
