Equalizing Batteries
975-0560-01-01 Revision B 3–13
NOTICE
In a system where more than one device is capable of equalizing batteries
(such as a system including multiple charge controllers and Xantrex XW
Hybrid Inverter/Chargers), there is no system-wide equalization command for
all devices. To equalize with multiple devices, each would have to be enabled
individually. Alternatively, equalization can be performed using only one
device. During the equalization process, one device applies the equalization
charge while the other devices continue to operate in synchronized charge
mode, typically in float (three-stage charging) or no float (two-stage charging).
WARNING
HAZARD OF EXPLOSION
Equalization charging generates explosive gases which might escape from
the battery. Make sure adequate ventilation is provided. Never leave a battery
unattended during equalization. Follow the battery manufacturer's
recommended actions for determining the appropriate point at which to stop
the equalization process, for example, by monitoring electrolyte specific
gravity.
Failure to follow these instructions can result in death or serious injury.
CAUTION
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.
CAUTION
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.
