Understanding the Charger Functions
Three-Stage Charging:
The Three-Stage Charging algorithm has a Bulk, then Absorption and then Float sequence.
During the Bulk stage, the battery accepts the maximum constant current from the charger. In
the Absorption stage, the battery voltage is held to constant voltage and the charging current
will slowly reduce. In Float stage, the charger continuously produces voltage at a lower level to
fully top up the battery and maintain the battery in a fully charged state.
The charger will automatically restart the charging cycle in Bulk stage if the battery is
discharged to 12.5V on 12V model IC 1230150, IC 1220100, or 24V model IC 244090i. Also,
after seven days, the charger will automatically restart the recharging cycle to refresh the
battery.
Battery Type:
Three types of battery setting (GEL, AGM and Flooded) are available. See reference battery
charging voltage as shown:

Equalize the Flooded Battery:
For Flooded battery type, equalization mode is available. Use the following procedure to
equalize the flooded battery. See also section 5 on setting EQ mode for flooded battery.
DANGER:Explosion Hazard. The flooded battery generates explosive gases during
equalization. Follow all the battery safety precautions listed in the manual.
CAUTION:Risk of Battery and Equipment damage. Only a Flooded lead-acid battery can be
equalized. Consult your battery manufacturer or read the battery manual when you try to
equalize your batteries. Disconnect any DC load connected to the battery, as during
equalization mode, the charger will produce 16V for 2000W, 3000W unit (IC 1220100,
IC1230150) or 32V for 4000W unit (IC 244090i) to the batteries that may damage some of
the DC load connected to the buttery. You must monitor the battery specific gravity
throughout the equalization to determine the end of the equalization cycle.
When EQ mode is set to ON, the unit will charge batteries in one full cycle before it starts to
equalize the battery. Check the battery electrolyte level. If necessary, refill with distilled water
only. All cells should have similar electrolyte levels. If distilled water is added, batteries must
undergo a complete charge cycle. The charger cannot determine when to terminate the
equalization of the battery. A 1 hour time-out is intended as a safety feature to terminate the
equalizing process. You can re-activate the EQ mode by setting it ON again as necessary
after checking batteries manually.
Optional Battery Temperature Sensor Feature:
Optional Battery Temperature Sensor Part Number #BTS-10K is highly recommended to be
used with the charger to protect your battery and provide better charging voltage accuracy. The
battery temperature sensor senses the battery temperature and makes adjustments to the
charging voltage.

Note: The charger will terminate battery charging when the Sensor senses the battery temperature reaching 60 °C.
It will not continuously make voltage adjustments when the battery temperature drops to below 0 °C.
