NOTICE
DC LOAD EQUIPMENT DAMAGE
Equalization voltage could be as high as 33.5V (for 24V systems) or 67V (for 48V systems)
and might damage some types of DC load equipment connected to the battery. Review the
maximum DC voltage specification for all equipment connected to the DC system and
disconnect any equipment that is not compatible with the configured equalize voltage.
Failure to follow these instructions can result in equipment damage.
Note: The Conext XW+ or Conext XW Pro Inverter/Charger and PDP will not be
damaged by equalization voltage and do not need to be disconnected during equalization.
However, these units may shut down depending on the setting of their over voltage
protection trip points.
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:
n On the Setup menu screen scroll to Equalize, and then press Enter.
n 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.
The charge controller applies the equalization charge for one hour. You can stop the
equalization process manually at any time by changing the setting to Disabled.
The one hour equalization timer will continue to run even if there is insufficient power from
the PV array to support this charge mode.
To determine when battery equalization is complete:
Follow the battery manufacturer's recommendations for equalizing the batteries. These
recommendations will include methods such as monitoring the specific gravity (SG) of
the electrolyte using a battery hygrometer and stopping the equalization when the SG has
stopped increasing.
n If the recommended point is reached before the automatic one hour equalization timer
runs out, then manually stop the equalization by changing the setting to Disabled.
n If the recommended point is not reached after one hour, the charge controller will
automatically exit the equalization stage. You can re-start equalization by following the
process above and continue equalizing until the battery manufacturer's
recommendation is met.
