Battery Types:
The SunWide’s standard battery charging programs are suitable for a
wide range of lead-acid battery types. These standard programs are select by DIP Switch
3~5.
Standard Battery Charging Programs
The SunWide provides 8 standard battery charging algorithms (programs) that are
selected with the DIP switches. These standard algorithms are suitable for lead-acid
batteries ranging from sealed (gel, AGM, maintenance free) to flooded to L-16 cells and
Ni-cad etc.
The table below summarizes the major parameters of the standard charging algorithms.
Note that all the voltages are for 12V systems (24V = 2X, 48V = 4X).
All values are 25ºC (77ºF).

Standard Battery Charging Programs
A. Battery Type
– These are generic lead-acid and Ni-cad battery types.
B. BULK Voltag
e–This is the PWM Absorption stage with constant voltage charging.
The “PWM voltage” is the maximum battery voltage that will be held constant. As the
battery becomes more charged, the charging current tapers off until the battery is fully
charged.
C. Float Voltage
–When the battery is fully charged, the charging voltage will be reduced
to 13.4 volts for all battery types.
D. Equalization Voltage
–During an equalization cycle, the charging voltage will be held
constant at this voltage.
E. Equalization Time
–The charging at the selected equalization voltage will continue
for this number of hours. This may take more than one day to complete.
