BATTERY TYPE SETTING - via DIP switch
Please check your battery manufacturer’s specifications to select the correct
battery type. The unit provides for 4 battery types: Gel, AGM, WET (conventional
lead acid), and LiFePO4.
There is a DIP switch at the back of the solar charge controller, this Dip switch is
used for presetting your battery type. Please refer to Figure 3.1 to make DIP
switch setting for the proper battery chemical; the factory default setting is AGM
battery type.
Note: Once the Dip switch setting is finished, do not change the DIP switch
unless disconnected from the battery; otherwise it may damage your battery.
The unit has a 5-stage charging algorithm.
Soft Charge (Level 1) – Bulk Charge (Level 2) – Absorption charge (Level 3) –
Equalizing Charge* (Level 4) - Float Mode (Level 5)
Figure 4.1
Soft Charge
When a battery suffers an over-discharge, the controller
will softly ramp the battery voltage up to 10V.
Bulk Charge
Maximum current charging until the battery rises to the
Absorption level.
Absorption Charge
Constant voltage charge when the battery is over 85%.
Equalization Charge*
Only for WET battery, when the battery is deeply drained
below 11.5V, it will automatically run this stage to bring
the internal cells to an equal state to reduce any loss of
capacity.
Float Charge
Battery is fully charged and maintained at a safe level
Voltage values are for 12V system, x 2 for 24V system
