Battery Equalization - INFOSEC UPS SYSTEM G1 Solar MPPT Manuel Utilisateur

BATTERY EQUALIZATION

Equalization function is added into charge controller. It reverses the buildup of negative chemical effects like
stratification, a condition where acid concentration is greater at the bottom of the battery than at the top.
Equalization also helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this
condition, called sulfation, will reduce the overall capacity of the battery. Therefore, it's recommended to
equalize battery periodically.

How to Apply Equalization Function
You must enable battery equalization function in monitoring LCD setting program 33 first. Then, you may
apply this function in device by either one of following methods:
1. Setting equalization interval in program 37.
2. Active equalization immediately in program 39.

When to Equalize
In float stage, when the setting equalization interval (battery equalization cycle) is arrived, or equalization is
active immediately, the controller will start to enter Equalize stage.

Equalize charging time and timeout
In Equalize stage, the controller will supply power to charge battery as much as possible until battery voltage
raises to battery equalization voltage. Then, constant-voltage regulation is applied to maintain battery voltage
at the battery equalization voltage. The battery will remain in the Equalize stage until setting battery equalized
time is arrived.
