Blinking Lights on the Remote Switch
You may encounter different sequences of blinking lights when the
inverter is enabled (i.e., switch is on) or the unit is charging. Light
sequences are described as follows:
Loads stop operating without
warning after they have been
running.
Shorepower is not connected.
Too many appliances have
reduced the battery voltage to
shutdown level.
Ambient temperature is too
high.
Reduce the number of loads.
Allow the inverter to cool and
restart. Recharge the batteries.
Disconnect appliances and let the
unit cool down.
The inverter will not work
even after toggling the switch,
charging the batteries, and
letting the unit cool down.
Remote switch may be
disconnected at the unit
Fuse on the unit (shown in
Figure 1-1) may have blown
Check that the remote switch is
firmly connected.
Replace the fuse or return the unit
to an authorized Xantrex dealer.
AC voltage at receptacles
reads low.
Wrong type of voltmeter being
used.
Use a true RMS meter
In inverter mode, times to
shutdown are getting shorter
for the same kind of AC load
Bad battery cable or corroded
battery terminals.
Batteries too old or damaged.
Check the cables and connectors
Replace the batteries.
