Operation

3.7 Inverter Startup

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 ﬁ gure 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. 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 (refer to ﬁ gure 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 says off after pressing the ON/OFF switch,

there is a “fault” condition such as low battery, high battery, overload, overtemperature

or an internal fault. Refer to the Troubleshooting section to help diagnose/clear the

fault condition.

Slow ﬂ ash (blinks on once every 8 seconds) - Indicates “ﬂ oat” charging; and the inverter

is in Standby Mode (the external AC power that is connected to the inverters input is passing

thru the inverter and is powering the AC loads connected to the inverter’s output).

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

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 inverter

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 inverters

input is passing thru the inverter and is powering the AC loads connected to the inverter’s

output).

On (solid) - Indicates “bulk” charging; and the inverter is in Standby Mode (the external AC

power that is connected to the inverters input is passing thru the inverter and is powering

the AC loads connected to the inverter’s output).
