I have a cargo trailer camper conversion, and want to install solar on it. I have bought a 12 volt 100 AH LiFepo4 battery to start, and the manufacturor recommends it be charged at 20 amps. I will be mounting a couple of 100 watt panels on the roof of the camper, but my question is which charge controller would be best for the battery? I have seen kits thta come with 20 amp and 40 amp controllers. Do I have to use a controller that advertises 20 amps?
