Have a 200watt panel on the roof and a Victron 15amp charge controller with two 24 group lead acid batteries. Looking to upgrade to eventually run the whole camper and the roof ac unit. It’s a 30 amp trailer. Not sure where to start. I’m trying to learn as I go. I would Imagine adding a 30w charge controller/ inverter would be a great place to start? I currently don’t have a inverter installed. Suggestions on how to proceed with upgrading ?
