PV input voltage is too high
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 10 first. Then, you may apply this
function in device by either one of following methods:
1. Setting equalization interval in program 14.
2. Active equalization immediately in program 15.
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.
