Operation
3.7 Inverter
Startup
Power ON/OFF Switch
– The inverter can be turned on/off by lightly pressing and releasing the
Power ON/OFF switch on the front (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 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
quali
fi
ed on the AC input, this AC power will also be available on the AC output and is
not controlled by the 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 (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 (such as low battery, high battery, overload, over-temperature,
or an internal fault). Refer to the Troubleshooting section to help diagnose/clear the fault.
• Slow
fl ash
(blinks on for 4 seconds, then off for 4 seconds) – Indicates the batteries are
fl
oat charging and the inverter is in Standby mode (the external AC power connected to
the inverter’s input is passing through the inverter and powering the inverter’s AC loads).
• 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
connected loads; 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; 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).
• 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 thru the inverter and is powering
the AC loads connected to the inverter’s output).
