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

NOTE
The Inverter/Charger will charge
the batteries with AC power applied
regardless of remote status.
Battery Temperature Sensor
A Battery Temperature Sensor (BTS) is
afxed to one of the house battery terminals
to measure battery temperature and send that
information to the inverter. When battery
temperature rises, the inverter will decrease
charge voltage to prevent boiling the batteries.
When battery temperature cools, the inverter will
raise charge voltage. Voltage compensation with
temperature variation is necessary to keep charge
voltage at optimum values. If the BTS cord is
unplugged from the inverter, the inverter will use
a temperature default setting of 77º F/25º C as a
reference point.

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.
