Operation
2–12
Battery charging
When you are connected to shorepower, the AC LED is illuminated and the
unit is both passing power through to the appliances and charging the
batteries. To avoid low voltage problems, make sure your connection cord to
shorepower is not too long and that it is heavy enough to support the loads
you are running. A 14 or 12 gauge extension cord is recommended.
If the AC LED flashes slowly (about twice per second), this means the AC
voltage is out of range and your batteries are not charging.
Using shorepower
If you are running too many appliances you may either trip the 15 amp truck
breaker or the shorepower breaker. Reduce the load and reset the affected
breaker.
Note that the charger will automatically reduce battery charging if other AC
loads are connected. This helps to prevent nuisance tripping of the
shorepower breaker.
Miscellaneous hints
Automatic
shutdown The inverter automatically turns off if it has not detected any AC loads for
24 hours or the loads are so small the inverter cannot detect them, such as an
alarm clock or very small television (less than 10-20 watts).
Output
power Remember that the total output of the inverter/charger is 1000 watts and not
1000 watts per outlet (if there is more than one).
.
Connect
delay to AC
power If you are connected to shorepower, the AC LED should be on and the
inverter LED off. The AC LED may blink slowly when you first apply
shorepower because of a connect delay (about 30 seconds), but then will
illuminate steadily.
Load failure If any loads fail to operate, or the inverter shuts down, refer to Chapter 4,
“Troubleshooting” for suggestions.
Note: The Xantrex HD does not provide any warning before it shuts
down. If you need to operate a critical AC load, be sure there are no
heavy loads connected and that the batteries have been recently charged.
