  • Page 25: Battery Equalization Description

    Power from PV energy only. The unit will provide output Battery Mode power from battery and PV power. Battery Equalization Description 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.
  • Page 26 However, in Equalize stage, when battery equalized time is expired and battery voltage doesn’t rise to battery equalization voltage point, the charge controller will extend the battery equalized time until battery voltage achieves battery equalization voltage. If battery voltage is still lower than battery equalization voltage when battery equalized timeout setting is over, the charge controller will stop equalization and return to float stage.
