Battery Charging with Inverter
The inverter will automatically charge when
AC power is supplied from shore service or the
generator. The inverter uses a three-stage charge
cycle to charge the batteries. The charger may
be turned off if desired.
To turn the charger on and off:
Press the switch marked CHARGER
ON/OFF on the remote panel.
Shore Setting:
The Shore setting in the remote panel adjusts
the amount of AC current the battery charger
can use. If hooked to less than 50 amp service,
select the proper Shore setting to help prevent
combined AC loads such as the roof air
conditioner and the charger from overloading
limited shore power service.
To Adjust Shore Power Setting:
Press the Shore button on the inverter
remote.
Turn the knob on the inverter remote left
or right to scroll through shore setting
options.
Press the knob to select. An arrow will
appear next to the selected setting.
NOTE:
Settings 20 Amp and below will limit
battery charge capacity and may
hamper ability to efficiently operate DC
electrical loads. Remember to reset to
higher amperage when available.

Set To:
Inverter three-stage charging cycle:
Bulk Charge Cycle: Brings the DC
voltage up high, initially between 14.2
- 14.6 Volts DC. The length of time the
inverter is in Bulk Charge depends the
state of charge of the batteries.
Absorb Cycle: Absorb Cycle battery
voltage is the same as the Bulk Charge
Cycle, between 14.2 - 14.6 Volts DC.
Length of the Absorb Cycle is a timed
event determined by the inverter.
Float Charge Cycle: Charge voltage is
generally around 13.3 - 13.7 Volts DC.
Approximately 80% of the charging
cycle has been completed by this time.
NOTE:
Refer to the OEM manual located in
the Owner’s Information File Box for
detailed instructions.

Bulk Charge
Water (charger) on full
until bucket (battery) is
80% full.
Absorb Charge
Water (charger) slows
until bucket (battery) is
90% full.
Float Charge
Water (charger) slowly
trickles into bucket
(battery) until 100% full.
Water (charger) will adjust
ow to maintain level.
