To recharge a 12v car battery in my cargo/camper trailer. Generally it would be sitting all day in partial shade/sun and the trailer would only get use at night. The usage would be quite minimal: a few LED lights, maybe a 12v fan for a short time if it particularly hot, maybe running a 12v water pump for a quick shower.
Thoughts?
