BAC Forum - BAC Forum Lots of knowledge for you here with these guys at the Beaver Ambassador Club.
We had the Heart in our 99 Safari Continental for ten years...no problems with anything we ever plugged in. Standard solar was a single 100 watt panel, sounds like someone has added on. If you have four house batts you will be in pretty good shape if you do indeed have 200 watts. The little one may be for starting batts, Those coaches generally came with a Xantrex Echo Charger to handle starting batts, but I replaced two before going another route. Good luck with your new baby.
