5.3.2 Charger Mode Messages
When AC power (utility or generator) is connected to the inverter/charger, it
begins to monitor the AC input for acceptable voltage. Once the AC input is
accepted, the AC transfer relay (inside the inverter) closes and Charge mode
begins. There are several Charge mode messages; view the LCD display and
the corresponding message in this section to identify and understand the
particular Charge mode.
Info:
The AC input becomes acceptable after a minimum 10-second
delay, and when the voltage is greater than the
VAC Dropout
setting.
• Absorb
Charging
Mode
– The Absorb stage is the constant voltage
stage and begins when the absorb voltage is reached (determined by
the
Battery Type
setting) while Bulk Charging. During this stage, the DC
charging current decreases as the battery becomes charged. This Charge
stage continues until the absorb charging time (determined by the
Battery
Amp-Hours
setting) is
fi
nished.
Absorb
appears on the LCD. The FAULT
(red) LED is off, and the INV (green) LED
could be on or off.

• Searching
Mode
– When the inverter is in Search mode, the AC loads
on the inverter output are less than the
Search Watts
setting. The Search
mode function is used to reduce the inverter draw from the battery, and may
be turned off whenever you want full inverter output voltage available at all
times.

appears on the LCD. The
INV (green) LED slowly

ashes. The
FAULT LED (red) is off.

– This message tells you that there is no AC available on the
inverter’s AC output. The inverter function is off.
