Inverter Startup

ON/OFF Switch - The inverter can be turned on and off by lightly pressing and releasing the Power
ON/OFF switch on the front of the inverter (see Figure 3-5). When the inverter is fi rst 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 (or reset per Section 4.4). Once the inverter has
been turned on, pressing the Power ON/OFF switch alternately turns the inverter on and off.
WARNING: The Power ON/OFF control switch does not turn on or off the charger
feature. If AC power (shore power or generator) is connected and qualifi ed on the AC
input, this AC power will also be available on the AC output and is not controlled by
the Power ON/OFF switch.
Status LED Indicator - The status indicator is a green LED (Light Emitting Diode) that provides
information on the operational mode of the inverter. Watch this indicator (see Figure 3-5) for at least
10 seconds to determine the inverter's operational condition from the information below:
• Off - Indicates the inverter is off; there is no AC power (inverter, shore power, or generator)
at the inverter's output terminals. If the LED stays off after pressing the ON/OFF switch,
there is a "fault condition" such as low battery, high battery, overload, over-temperature,
or an internal fault. Refer to the Troubleshooting section to help diagnose/clear the fault
condition.
• Slow fl ash (blinks on once every 8 seconds) - Indicates fl oat charging; the inverter is in
Standby Mode (the external AC power that is connected to the inverter's input is passing
through the inverter and is powering the AC loads connected to the inverter's output).
• Medium fl ash (blinks on once every second):
When AC power is not connected to inverter input - Indicates the inverter is on and using
energy from the battery. The inverter is either: 1) Inverting - providing full power to the
loads connected to the inverter; or, 2) Searching - conserving power and waiting for a load
to be turned on that meets or exceeds the search watts parameter (5 watts is the inverter
default setting).
When AC power is connected to inverter input - Indicates absorb charging; the inverter is
in Standby Mode (the external AC power that is connected to the inverter's input is passing
thru the inverter and is powering the AC loads connected to the inverter's output).
• On (solid) - Indicates bulk charging; the inverter is in Standby Mode (the external AC
power that is connected to the inverter's input is passing thru the inverter and is powering
the AC loads connected to the inverter's output).
