My boat has a Xantrex prosine
3.0 inverter charger
. It works perfectly at the dock
, maintains my batteries at 100%. Today, to simulate cruising, I disconnected from shore power
and used my inverter
to run my shop vac at length several times. By the end of the day my batteries were at 85%. When I plugged in my Honda
genny, it would run fine, then bog, as if experiencing a heavy load. Then it would go back to normal, and repeat this chain of events
again, every 15-20 seconds. My battery monitor
showed that when the genny bogged, the charger
would come on briefly, then the charger would go off, and the genny would resume its normal running.
I checked all connections, switched power cords, all with the same result. When I finally plugged back into shore power
, my monitor
showed 14.6 volts at 50 amps charging!! Is there some way to set the charger to start out at a lower amperage for the generator
? I don't think it likes 40-50 amps.
