Blinking lights on the remote switch
This table describes the different sequences of blinking lights you may
encounter when the inverter is enabled (switch is on) or the unit is
charging (switch is off). Light sequences are described as follows:
L
Loads stop operating without
warning after they have been
running for awhile
Shorepower not connected
Too many appliances have
reduced battery voltage to
shutdown level
Ambient temperature is too
high
Reduce number of loads. Allow
inverter to cool and restart. Start
the truck to recharge the batteries.
Disconnect appliances and let the
unit cool down
Inverter will not work even
after toggling switch and
batteries are charged and the
inverter is cold
Remote switch may be
disconnected at the unit (not
likely)
Fuse on the unit (shown in
Figure 1-1) may have blown
(not likely)
Check that the remote switch is
firmly connected
Replace fuse or return unit to an
authorized Volvo dealer
AC voltage at receptacles
reads low
Wrong type of volt meter 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 cables and connectors
Replace batteries
