Operation
3.5
Inverter 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 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 6.1). 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 switch does not turn the charger feature on/off or
remove pass-thru power. If AC power (utility or generator) is connected and qualifi ed
on the AC input, it is also available on the AC output.
Info: The Power ON/OFF pushbutton on the inverter is a small momentary type switch
which operates by lightly pressing and releasing. Only press forward on this switch, do
not press or apply force on the switch sideways or the switch might break.
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 Figure 3-5) for
at least 10 seconds to determine the inverter's operational condition using 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, 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 second) –
When AC power is not connected to the inverter's 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 = 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 inverter's input is passing
through the inverter and is powering the AC loads connected to the inverter's output).
•
Fast Flash (blinks on/off very quickly—fl utters) – Indicates the inverter is in equalize charge
(requires remote to enable) or the inverter is continuously in reset. If a remote was not used to
enable the equalize charge, then suspect the inverter is in reset. Refer to the Troubleshooting
section to help diagnose 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).
