  • Page 37: Battery Equalization Description

    Battery Equalization Description Battery equalization function is built into the charge controller. It reverses the build-up of negative chemical effects such as 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 may have built up on the plates.

  • Page 38: Fault Reference Code

    However, in Equalize Mode, if the battery equalization timer runs out and the battery voltage doesn’t recover to the battery equalization voltage point, the charge controller will extend the battery equalized time until battery voltage achieves equalization voltage. If the battery voltage is still lower than equalization voltage when the extension runs out, the charge controller will stop equalization and return to the floating charging stage.
