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 Search mode. The green INV LED is on when the inverter is actively
inverting, and fl ashes while searching.
Turning the inverter off: While the inverter is actively inverting or
searching, press the ON/OFF INVERTER button to switch the inverter function
off. This will turn the green INV LED off.
Inverter Standby – The inverter is a slave unit in a parallel stacked system.
Inverter Standby occurs when the inverter 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 connected to the inverter are
powered by the other inverters in the parallel stacked system. The standby
inverter will come on automatically if the AC loads increase and require more
inverter power.

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:
Absorb Charging, AC Coupling, Bulk Charging, Charger Standby, Charging,
Equalizing, Float Charging, Full Charge, Load Support AAC, Load Support
VDC, and Silent.
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, press the ON/OFF CHARGER button 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 stratifi 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
Figure 5-11 and the information on page 43.
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.
