• Full Charge
– 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 will turn off and “
Full
Charge
” is displayed (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 will automatically initiate 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.

Load Support AAC
Settings/Info..
Figure 5-14, Load Support AAC Mode
• Load Support AAC
– The inverter is in the 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 inverter batteries to keep the incoming AC
current from exceeding the
SHORE: Shore Max
setting.
Info:
The
Load Support AAC
feature operates in parallel with the
AC input to support the inverter loads and is only available on MSH
Series inverter/chargers. It is only active when the AC input is quali-
fi
ed and connected, and the inverter is enabled (INV LED is on).
• Float Charging
– At the end of the Absorb Charging time, the
charger reduces the charge voltage and tries to maintain the batteries at
the Float Charge voltage setting. This is determined by the SETUP menu’s
04 Battery Type
setting as shown in Table 3-4.
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.
