Fault Reference Code - MPP Solar PIP3624MT User Manual

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.
