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 (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 4.4). 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 (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.
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
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).
• 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).
