Start-up
ON/OFF Switch - Turning the inverter ON and OFF is controlled by a
momentary switch on the front of the inverter (see Figure 2, Item 2).
When the inverter is connected to the batteries, or when its automatic
protection circuit has turned the inverter off, the ON/OFF switch will
need to be pressed to start the unit. Once the inverter has been
turned on, pressing the ON/OFF switch alternately turns the unit on
and off.
Info: The ON/OFF control switch is a small momentary
switch which functions by lightly pressing and releasing.
Status Indicator - The status indicator is a green LED that provides
information on the operational mode of the inverter. Watch the status
indicator (see Figure 2, Item 1) for at least 10 seconds to verify or
determine the operational condition from the information below.
Normal Operation
• Off - The inverter is off. There is no AC power from inverter,
shore, or generator at the inverter’s output terminals.
• On (solid) - The inverter is in Transfer Mode. The external AC
power (utility power or generator) connected to the inverter’s
input is passing to the inverter’s output to power the AC loads.
• Blinks on once every second - The inverter is on and using energy
from the battery. The inverter is either providing full power to the
loads connected to the inverter, or it’s in Search Mode and ready
to supply AC power to the loads connected to the inverter.
Protection Mode
There are fi ve fault conditions that will cause the inverter to shut
down; Low Battery, High Battery, Over-temperature, AC Overload,
and Internal faults. If your inverter has shut down, monitor the sta-
tus indicator and count the number of blinks that occur every four
seconds to determine the particular reason for the shutdown. Once
you have determined the reason for the shutdown, refer to the
Troubleshooting section to help diagnose/clear the fault condition.
• Blinks on 1 time every four seconds - Low Battery fault.
• Blinks on 2 times every four seconds - High Battery fault.
• Blinks on 3 times every four seconds - Over-temperature fault.
• Blinks on 4 times every four seconds - AC Overload fault.
• Blinks on 5 times every four seconds - Internal fault.
Charge Mode
Some units are equipped with the internal battery charger – with
this option the green LED status indicator provides additional infor-
mation:
• Blinks off every four seconds - The unit is charging the batteries
connected to the inverter.
