An equalization charge is not a standard charging phase, it is a planned over-charge of the batteries that can help to reduce the long-term deterioration of batteries due to a buildup of sulfation on the lead plates inside. The voltage of the battery bank may be increased as high as ~16.2V for a specified period of time. Not all charge controllers have this capability. Only flooded lead acid batteries can undergo an equalization charge. The user must either schedule or activate an equalization charge and it should only be done a day with abundant sun as the over-charge will require more energy than normal. Equalize flooded lead acid batteries at least once per month for 2 to 4 hours, longer if your batteries have been consistently undercharged.
