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

qualiﬁ 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).
