If solar charge controller is working in float stage, but at this time, the setting
equalization interval (battery equalization cycle) is arrived, it will transfer to
equalize stage.
Equalize charging time and timeout
In Equalize stage, based on maximum charging current of battery equalization, the
controller will supply solar power to charge battery as much as possible until battery
voltage raises to battery equalization voltage. Then, constant-voltage regulation is
applied to maintain battery voltage at the battery equalization voltage.
The battery will remain in the Equalize stage until setting battery equalized time is
arrived.
However, in Equalize stage, when battery equalized time is expired and battery voltage
doesn’t rise to battery equalization voltage point, the solar 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 solar charge control will stop equalization and
transfer to float stage.
