AMP capacity

Sorry for the rookie question, but here goes: I am thinking of installing battery chargers and a shore power system to power them, but I'm not clear on how amp capacity works. Most branch circuits in distribution panels are 15 amp, but I am in possession of a 30 amp charger. Will I need to upgrade the panel to handle this load?

Your 30 amp battery charger should draw less than five amps on the A.C. side, so your AC side is fine. That 30 amp rating is how much it puts into your batteries at 14V.

SanderO is an unknown quantity at this point
This has nothing to do with your DC circuit rating. It is the rating of how many amps the charge can supply to the batts.
