Roadtreking: Adding solar to your older Class B

From the bloggers at Roadtreking.

Two years ago we added solar to our then 18-year old Roadtrek 190 Popular. We followed the rule of thumb you often hear, “Add 100 watts of solar for every 100 amp hours of battery.” We had one 80 amp hour battery.

After much research and a lengthy discussion with the vendor on requirements we bought an entire system from AM Solar for $695 and installed it ourselves.

Two years down the road we revisited the subject. Should we change anything?  Should we have done anything different? In retrospect we would have gone with a different controller than our Morningstar SunSaver 15 MPPT (which AM Solar no longer sells), but both of the controllers we would choose today were not available back then.

We eventually added a solar cut-off switch because we managed to “boil” our poor battery big time by leaving the camper plugged into shore power after the snow on the roof melted.

The solar system woke up each morning and went into bulk charge for 3 hours on our already fully charged battery.
