How Many 190 Watt Panels Can be Used with 30 Amp Controller of RV Solar Panel Setup

Published 02/02/2022

Question:

I first installed the Overlander kit with the 190w panel on my Thor Class A and then added another 190w GoPower panel. After a year of serious boondocking, I expanded my battery bank to two 210AH AGM batteries. I feel I could use another dose of sunshine but with the 30 amp controller. I would be at my limit with another 190w panel. Can I add another 190 w panel safely? Or is it possible to tie in maybe a 100 w panel to my existing set-up? Thanks for your time!

Yes you'd easily be safe to add another Go Power Overlander Expansion Kit # 34282182 to your GoPower setup that has a 30 amp controller. You'd be close to the max amperage but you'd be under the 30 amps pretty easily even if they were at peak, but even if you did go over the controller's amperage rating it wouldn't have an issue as nothing would happen.
