Follow the battery manufacturer’s recommendations for equalizing your batteries.
As a guide, a heavily used flooded battery might need to be equalized once a
month, while a battery in light service might only need to be equalized every two
to four months.
The equalization process lasts one hour. When the equalization period has
expired, the charge controller will return to either the float or no float charge
stage.
To enable battery equalization:
1. On the Setup menu screen scroll to Equalize, and then press Enter.
2. Change the setting to Enabled.
The charge controller goes back to the bulk stage and goes through bulk and
absorption before entering the equalization stage. The full charge cycle makes
sure the batteries are fully charged before an equalization is initiated.
NOTICE
BATTERY DAMAGE
Never equalize a battery more than necessary. Equalization can damage your
batteries if performed too frequently or done improperly. Always check
electrolyte level before and after equalization. Fill with distilled water according
to the battery manufacturer’s recommendation.
The charge controller enables equalization only when the battery type is set to
Flooded. Equalize mode is disabled if you have selected GEL and AGM as the
battery type. As a general rule, do not equalize a battery unless there are
provisions to add water to it and the manufacturer recommends equalization.
Failure to follow these instructions can result in equipment damage.
NOTICE
DC LOAD EQUIPMENT DAMAGE
Equalization voltage could be as high as 32 V (for 24 V systems) or 64 V (for
48 V systems) and might damage some types of DC load equipment
connected to the battery. Disconnect any loads that are not rated to withstand
the applicable equalization voltage.
Failure to follow these instructions can result in equipment damage.
NOTE
The Conext XW+ Inverter/Charger and PDP will not be damaged by
equalization voltage and do not need to be disconnected during equalization.
