5.0 Operation
• Float
Charging
Mode
– At the end of the Absorb Charging stage, the
charger reduces the charge voltage and tries to maintain the batteries at
the Float Charge voltage setting—which is determined by the
Battery Type
setting. See Table 3-3.
Info:
If the battery voltage falls
≤
12.1 VDC (12-volt models),
≤
24.2
VDC (24-volt models) or
≤
48.4 VDC (48-volt models), the unit will
begin Bulk Charging.

appears on the LCD. The FAULT
(red) LED is off, and the INV (green) LED
could be on or off.
• Full
Charge
Mode
– This status indicates that you have entered
the Battery Saver™ mode. This mode maintains the batteries without
overcharging, thus preventing excessive loss of water in
fl
ooded batteries or
drying out of GEL/AGM batteries. After 4 hours Float Charging, the charger
turns off and “
Full Chg
” displays (charger is now in Battery Saver™ mode). If
the battery voltage drops to
≤
12.6 (12-volt models),
≤
25.2 (24-volt models)
or
≤
50.4 (48-volt models), the charger automatically initiates another 4 hours
of Float Charging. This cycle helps to ensure the batteries are monitored and
maintained, and continues as long as AC power is continuously connected
to the AC input.

Figure 5-13, Load Support AAC Mode
• Load Support AAC
Mode
– The inverter is in Load Support (amps AC)
mode because the inverter load is requiring more power than the incoming
AC source can provide on its own. The inverter pulls the additional current—
needed for the loads—from the batteries to keep the incoming AC current
from exceeding the
AC IN
setting.
