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 Search 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 searching, 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 powering AC loads from the batteries. If in a standalone system, the inverter is
in Inverter Standby when the charger is active (i.e., Charge mode). In a parallel system, inverter
standby occurs to slave inverter when it is monitoring the power requirement of the parallel system
to determine when to activate and provide power to assist the master inverter.
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: Absorb Charging, Bulk Charging, Charger Standby, Charging, Equalizing,
Float Charging, Full Charge, Load Support AAC, Load Support VDC, and Silent. (When the charger
is ON and actively charging, it produces DC voltage and current to charge your batteries, and the
CHG LED is solid.)
CAUTION: If you have critical loads and are in Charge mode, do not press the ON/OFF
INVERTER button, or you may inadvertently turn the inverter function off. While in any
Charge mode, ensure the green INV LED is ON, or inverter power will NOT be available
to run your critical loads if the external AC power is interrupted.
Charger Standby: While the charger is actively charging, press the ON/OFF CHARGER button to
switch the charger to Charger Standby. When 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 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 mixes battery electrolyte (to reverse the buildup of stratifi cation) and removes
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 pages 59-60.
WARNING: Do not perform an Equalization charge without reading and following all
safety precautions pertaining to charging/equalization as noted in this manual and
provided by the battery manufacturer.
5.3 System Status Messages
A status message may be an operational or fault message indicating the inverter/charger’s current
operating status. This section will cover the inverter/charger’s operating and fault modes, and the
available status messages under each mode.
Use the displayed status message and the status LEDs on your router to determine the inverter/
charger’s current operating status, and to help troubleshoot the system if a fault occurs.
The System Home screen displays inverter/charger status messages on the top line and any
accessory status messages on the second line (see Figure 5-3.1). The FAULT LED fl ashes to indicate
that one of the ports has a fault. To determine which port has the fault, press the PORT button or
rotate the SELECT knob until the FAULT LED turns solid. The fault now displays on the second line.
The fi rst line identifi es if it is an inverter/charger fault or an accessory fault (see Figure 5-3.2).
