Let me first provide our setup:
- Phoenix charger 12/50
- Phoenix inverter
- Phoenix control panel
- 2 x12V 220ah AGM blue energy batteries
- 2 x 12V Exide batteries (I think there are start only batteries)
If I understand correctly, we have 16 amp shore power. But when I connect our boat to the shore power I can read on the Phoenix control panel the battery charge is often time >30A. I am very confused how this is possible and why the shore based 16 amp breaker is not tripping?
I notice when I turn down the charge control on the control panel to 30 ish % the display shows a charge of 12 A.
My question really is… how should I read the battery charge amperage on the control panel and relate it to the shore power? and what is the recommended setting of the charge current % given the shore power available?
Lets say that the boat uses about 5 amps when docked and not used (inverter on, fridge on, security camera on, MiFi router on).
