IMHO one of the best videos available on YouTube explaining how to choose a charge controller:
Video presenter is Garrett Towne, AMSolar engineer (and I believe owner of the business).

Okay his explanation of the difference between the two charge controllers and voltage outputs from controller was worth the watch. My daughter just bought a wolf pup with the ten amp solar controller which is not mppt. The trailer has one fifty watt panel an we decided to add one 100 watt panel in parallel if we had gone series the battery would have had troubles. So thanks for this video.
