Got the ac200 in Nov, used it until 2/20 while full-timing in my travel trailer. Hooked to a 350 W panel I got from Santan Solar. Worked well. Then I had a full hook-up site from 2/20 to 3/11, so didn’t use the unit. Had the solar panel disconnected and turned on the ac200 a couple of times to check it. Was at 100% both times. So now I’m off grid again. But when I connect the panel, I get nada.
It charges via ac when I plug the trailer into a generator and charged via the car plug while driving.
The panel shows proper voltage thru a multimeter. And I have the dc input source set to PV.
