Thank you Chance & wing; very informative. Yes, my panels are mounted horizontal and connected to each other with 10 gauge wire. Final run from the roof to the controller is 4 gauge welder’s wire. Panels were clean and garaged up until we left on the trip. Texas to Indiana, then Ohio, KY, VA, and a southerly route back to Texas. I checked the controller a few times each day while traveling and parked. Output ranged from 200’s to 400’s watts and low teens to upper 20’s for aH. Having never had solar, I didn’t know what to expect.
