5 .3 Standard Diversion Battery Charging Programs
The SunStar provides 8 standard diversion charging algorithms (programs) that are selected
with the DIP Switches.
The table below summarizes the major parameters of the standard diversion battery charging
algorithms. Note that all the voltages are for 12V systems (24V = 2X, 48V = 4X).
A. PWM BULK Voltage
- This is the PWM Absorption stage with constant voltage char-
ging. The PWM absorption voltage is the maximum battery voltage that will be held
constant.
B. Float Voltage
- When the battery is fully charged, the charging voltage will be reduced to
13.4 volts for all diversion settings.
C. Equalization Voltage
- During an equalization cycle, the charging voltage will be held
constant at this voltage. Equalizations are manual, and can be selected for automatic.
D. Equalization Time
- Charging at the selected equalization voltage will continue for this
setting number of hours.
E. Equalization Interval
- Equalizations are typically done once a month cycles can be set
in the Equalization Interval in units of days so the equalization will begin according to the
setting value. Each new cycle will be reset as the equalization starts.
All values are 25ºC (77ºF) .
