Float cancel voltage
Once the battery voltage drops to setting point of Float cancel voltage, the
controller also returns to Bulk charging stage.
Float cancel voltage = Floating charging voltage – (1V x battery numbers in series)
5.2 Equalize Stage
Equalization function is added into solar 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.
