Operation
3.7 Inverter Startup
Power 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 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.
Charging/Inverting 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, utility, 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.
• Blinks on 4 seconds, then is off 4 seconds – Indicates Float Charging; the external AC
input power is passing through the inverter and powering the AC loads connected to the
inverter’s output.
• 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 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 external AC input power is passing thru the inverter
and powering the AC loads connected to the inverter’s output.
