Three-Stage Battery Charging
Battery voltage and current vary during the three-stage charging process
as follows.
BULK
During this stage, the batteries are charged at the bulk voltage setting and
maximum current output of the DC source. When the battery voltage reaches
the BULK voltage setting, the controller activates the next stage (absorption).
During the bulk charging process, the status LED (green) may blink from one to
five times before pausing. The more times it blinks consecutively, the closer the
battery voltage is to the BULK voltage setting.
ABSORPTION
During this stage, the voltage of the battery is held at the BULK voltage
setting until an internal timer has accumulated one hour. Current gradually
declines as the battery capacity is reached. During the ABSORPTION stage,
the status LED (green) blinks five times, then pauses and repeats.
FLOAT
During this stage, the voltage of the battery is held at the FLOAT voltage
setting. Full current can be provided to the loads connected to the battery
during the float stage from the PV array. When the controller has reached the
FLOAT stage, the status LED (green) will be solid green.
