5.0 Operation
5.2 Operating the Inverter/Charger
5.2.1 Inverter Mode
Turning the inverter on:
Press the ON/OFF INVERTER button to activate the
inverter function. The inverter will either be actively “inverting” by using power
from the batteries to power the AC loads; or, the inverter will be “searching”
for a load by using very little power from the batteries, if in Searching mode.
The green INV LED is on when the inverter is actively inverting, and the green
INV LED
fl
ashes while searching.
Turning the inverter off:
While the inverter is actively inverting or search-
ing, press the ON/OFF INVERTER button to switch the inverter function off.
This turns the green INV LED off.
Inverter Standby
– The inverter is in Inverter Standby mode when it is
enabled (green INV LED is on) but not actively providing power from the
batteries to the inverter loads. During Inverter Standby mode, the loads con-
nected to the inverter are powered by the external AC power; however, if a
blackout or brownout condition occurs, the inverter senses these conditions
and starts inverting to power the inverter’s AC loads.
CAUTION:
If you have critical loads and are in Inverter Standby,
do not press the ON/OFF INVERTER button to turn the inverter
function off. If the green INV LED is off, inverter power will NOT
be available to run your critical loads if the external AC power is
interrupted.
5.2.2 Charger Mode
Turning the charger on:
The Charge mode is automatically activated and
begins when acceptable AC power (utility or generator) is connected to the
input of the inverter. When in Charge mode, the display may show:

Bulk Charging
,
Absorb Charging
,
Float Charging
,
Full Charge
,

,

and
Load Support AAC
.
Charger Standby
– While the charger is actively charging, press the ON/OFF
CHARGER button to switch the charger to Charger Standby. While in Charger
Standby, the incoming AC is still available on the inverter’s output, but the
charger is not allowed to charge. The LCD displays “
Charger Standby
” and
the CHG LED
fl
ashes.
Info:
To resume charging, momentarily press the ON/OFF CHARGER but-
ton or disconnect/reconnect AC power to the inverter’s input.
Equalize Charging
– Equalizing is a “controlled overcharge” performed after
the batteries have been fully charged. It helps to mix the battery electrolyte
(to reverse the buildup of strati
fi
cation) and to remove sulfates that may
have built up on the plates. These conditions if left unchecked, will reduce the
overall capacity of the battery. To enable the Equalization charge, see page 53.
WARNING:
Do not perform an Equalization charge without read-
ing and following all safety precautions pertaining to charging/
equalization as noted in this manual and provided by the battery
manufacturer, and any equalization information in the inverter
owner’s manual.
