What size solar charger to maintain batteries

Hi wbrowning,

60 to 150 watts per 100 amp-hours will allow equalization, automatically, which is best for a battery bank. 30 watts per 100 will do maintenance charging between trips. If you do not wish to use a controller 10 watts per 100 sorta kinda works.

What is the size of the battery bank? Do you wish to maintain the chassis battery too?
