I have a 4 year old victron 12v 80a charger in a boat with 16a shore power, charging 3 x 220ah l/a batteries. Located in engine room which is pretty dry. I leave if off normally as don’t like to cook the batteries. The Problem is, unless I leave a dehumidifier running in the E/R and it’s super-dry, the charger trips the breaker circuit when switched on It’s very susceptible to moisture. Any ideas?
