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 (Figure 3-9). 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, or remove pass-thru power. 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 (Figure 3-9) 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 any fault condition.
• Slow Flash (blinks on for 4 seconds, then off for 4 seconds) – Indicates the batteries are
fl oat charging and the inverter is in Standby mode (any external AC power connected to the
inverter's input is passing through the inverter and powering the inverter's AC loads).
• Medium Flash (blinks on once every two seconds) – indicates the inverter is Inverting, using
energy from the battery and providing full power to the connected loads.
• Fast Flash (blinks on once every second) –
When AC power is not connected to the inverter's input: Indicates the inverter is Searching—
conserving power and waiting for a load to be turned on that meets or exceeds the Search
Watts parameter (5 watts = default setting).
When AC power is connected to the inverter's input: Indicates absorb charging, and 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).
• Very Fast Flash (blinks on/off very quickly—fl utters) – Indicates the inverter is in EQ charge
mode (requires remote to enable), or the inverter is continuously in reset. If a remote was
not used to enable the equalize charge, then the inverter is likely in reset. Refer to the
Troubleshooting section to help diagnose/clear the fault condition.
• On (solid) – Indicates bulk charging, and 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).
