3.5 Start-Up
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 (refer to fi gure 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 4.1). 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 (Utility 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 (refer to fi gure 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, utility or generator) at the
inverter’s output terminals. If the LED says off after pressing the ON/OFF switch, there is a “fault”
condition such as low battery, high battery, overload, overtemperature 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; and the inverter is
in Standby Mode (the external AC power that is connected to the inverters input is passing thru
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; and the in-
verter is in Standby Mode (the external AC power that is connected to the inverters input is
passing thru the inverter and is powering the AC loads connected to the inverter’s output).
• On (solid) - Indicates “bulk” charging; and the inverter is in Standby Mode (the external AC
power that is connected to the inverters input is passing thru the inverter and is powering the AC
loads connected to the inverter’s output).
