2-1 Operating Modes
There are three distinct operating modes programmed into each SC Lighting Control Series.
Different from SC MPPT Series, only one mode of operation being selected for an individual
unit, SC Lighting Control Series can be operated at Solar Battery Charging mode and DC
Load Control or Lighting control mode at the same time.
Solar Battery Charging
The energy output of a solar array is used for recharging the system battery.
The SC Lighting Control Series manages the charging process to be efficient and to maximize
the life of the battery. Charging includes a bulk charging stage, PWM absorption, float and
equalization.
DC Load Control
When set for DC load control, the SC Lighting Control Series powers loads from the battery,
and protects the battery from over-discharge with a current compensated LVD (low voltage load
disconnect).
Lighting Control
When set for lighting control, the SC Lighting Control Series would detect day and night and
measure the length of night at different time and area zone. The desired lighting hours can be
set for the precise control to turn on and turn off the light in order to achieve power saving.
2-2 Adjustability of Solar Battery Charging
Seven DIP switches permit the following parameters to be adjusted at the installation site:

PWM Battery Charging
PWM (Pulse Width Modulation) battery charging is the most efficient and effective
method for recharging a battery in a solar system.
Selecting the best method for charging your battery together with a good maintenance
program will ensure a healthy battery and long service life. Although the SC Lighting
Control Series's battery charging is fully automatic, the following information is
important for getting the best performance from your SC Lighting Control Series
controller and battery.
