Equalizing Batteries

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.
• 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.
• 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.
To manually stop battery equalization:
1. On the Setup Menu, scroll to Equalize, and then press Enter.
2. Change the setting to Disabled.
Equalization stops, and the charge controller goes to either the float or no float
stage, depending on the charge mode selected.
