5.3.2 Charger Mode Status 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 Charger mode messages. View the top line of the
LCD display and the corresponding message in this section to determine and
understand the particular Charger mode.
Info:
The AC input becomes acceptable once: a minimum 10-second
delay passes, the voltage is greater than the SETUP menu’s
03D
VAC Dropout
setting, and no
AC In Control
menu setting is actively
preventing the AC from connecting.
• Absorb
Charging
– The Absorb charge state is the constant voltage
stage and begins when the absorb voltage is reached (determined by the
SETUP menu’s
03B Battery Type
setting) while Bulk charging. During this
stage, the DC charging current decreases in order to maintain the absorb
voltage setting. This charge stage continues until the
03E Absorb Done
(Time, Amps, or SOC) or
03F Max Charge Time
setting is reached.
• Bulk
Charging
– The battery charger is delivering maximum current
(determined by the SETUP menu’s
03C Max Charge Rate
setting) to the
batteries. The charger remains in Bulk charge until the absorb voltage
(determined by the SETUP menu’s
03B Battery Type
setting) or the
03F Max
Charge Time
setting is reached.
• Charger
Standby
– This indicates the charger has been disabled to
prevent further charging, but the AC power (from utility or generator) to the
AC input is still available on the AC output. This display is shown when the
ON/OFF CHARGER button is pressed while the AC power is passing through
the inverter/charger.
Info:
Press the ON/OFF CHARGER button to enable charging again.
When enabled, the charger will continue in the previous charge mode
and the CHG (green) LED will come on solid.
• Charging
– Once Charger mode has been enabled, the unit will
wait and display “
Charging
” to determine the charge routine. If the DC
voltage is low (
≤
12.8 VDC/12-volt models,
≤
25.6 VDC/24-volt models, or
≤
51.2 VDC/48-volt models), the charger will initiate Bulk Charging. If the
DC voltage is high (
≥
12.9 VDC/12-volt models,
≥
25.6/24-volt models, or
≥
51.2/48-volt models), the charger will skip the Bulk and Absorb charging
stages and go directly to the
fi
nal charge stage (Float or Silent).
• Equalizing
– This display indicates that the battery charger is delivering
the equalize voltage to the batteries. See Table 3-1 to determine the equalize
voltage for your battery type.
Equalize charging can be enabled by the ON/OFF CHARGER button if the
SETUP menu’s
03B Battery Type
setting allows. Equalization charging can
only be enabled while the charger is in Float Charge or Full Charge mode. To
turn on Equalize charging, ensure the LCD display reads “
Float Charging”
or “
Full Charge”
, then press and hold down the ON/OFF CHARGER button
(about
fi
ve seconds) until the LCD screen displays “
Equalizing”
.
The Equalize charge will continue for four hours and then automatically stop
and return to Float charging. The Equalize charge can be manually stopped
by pressing and holding down the ON/OFF CHARGER button (about
fi
ve
seconds) until the LCD screen displays “
Float Charging”
.
