is still on the hard
, but getting ready to launch hopefully in 3 weeks. I was at the boat cleaning
and prepping yesterday and noticed I have an AC problem.
1. How do I determine whether the inverter charger
is actually dead?
2. Any recommendations for replacement?
The boat has dual 30-amp inlets, one that powers the air con unit only and one that powers the panel, a/c outlets and the Xantrex PROSine
2.0 inverter charger
installed around 2004 by the previous owner. It is installed in the seat under the nav station (terrible location!) and accessing either end requires the unit to be unbolted. It has a remote
monitoring panel. I am connected to the correct inlet and the circuit breaker at the inlet is not tripped. The main electrical
panel shows shore power
was connected. I verified I had 120 v at the inlet using a multimeter. The remote
panel for the PROSine
also indicates it saw 120v AC, but it showed ZERO amps coming in and zero amps going to the batteries
. The batteries
are all 3 year old AGMs which are now dead and showing less than 7 volts at the PROSine panel and probably now need replacement. I had no power at any AC outlet either with the inverter (no surprise with the batts that dead) or without the inverter just using shore power
. The remote panel has a switch that disables or enables the inverter. In the past, I have had AC power with the inverter disabled when connected to shore power.
I do not have a bypass for the inverter charger, so I cannot easily isolate it. I also have not yet installed the Balmar battery monitor
I have which is still in its box.
I'm not sure it's relevant, but I have 3 battery
banks - one house and one starting, both set up for charging
through both the alternator
and the inverter charger, and one in the bow which is charged by shore power only.
How can I troubleshoot the inverter charger to determine whether it is working or is now just so much useless weight?
If it's dead and needs replacement, any recommendations for replacement? Boat is a 12 volt system and spends most of its time on a mooring
with no shore power. Shore power is connected while on the hard
in the winter
(only while on the boat, not full-time as required by the marina/yard) and while visiting other marinas
on occasional overnights. 18 years for the PROSine seems like a decent life span, so I would consider a new Xantrex charger. I have a Victon MPPT solar
charger for my single solar
panel (solar upgrades are still in the planning stages), so I would also consider a Victron, especially if it had Bluetooth like my MPPT
controller. Are there others worth considering?
