Select one of the 7 standard battery charging algorithms, or select NiCad to determine the
charging of the battery.
※ The above setting voltage value is in the condition of 12V system. The voltage will be
twice of above values in the 24V system and it will be four times of above values in the
48V system.
※ Refer to section 8.0 of the manual for battery charging information.
※ The 7 standard charging algorithms above are described in section 4.2-standard battery
charging programs.
DIP switch number 7- Battery Equalization
Switch 7 Battery Equalization

OFF Manual Equalization
※ In the Auto Equalization Mode (Switch number 7 ON), the SunStar controller can
automatically triggering of the equalization process. When automatic has been selected,
an equalization charge will occur at set voltage and time (hours and days).
During the equalization process, the status LED indicates equalization (Equalization is
not recommended for NiCad batteries and is disabled). The equalization process will
continue until the voltage has been held above the bulk setting for a cumulative period of
set hours as shown above. This might take several days on larger system with big
batteries and small solar arrays. The battery voltage only needs to exceed the bulk setting
