But even with the battery switch OFF they won't hold a charge. Goes to like 8 V
Should the 2 A charger keep the new coach batteries charged?
Your battery switch should be OFF ONLY when the RV is stored and not used. If the solar will be active during storage, the switch probably NEVER needs to be OFF.
If the batteries are going below 8 volts, you aren't using something right. Except in some kind of emergency situation they never should go below 10.
And yes the solar controller should KEEP the batteries charged at the 2 amp setting, when in storage, but it might not recover them from a deep discharge. It is also possible that it won't keep up with your "normal" use when occupied.
Since you are "hosting" aren't you plugged into shore power all the time ? If so, the solar is kind of redundant.
