2. Connection Procedures (refer to Connection diagram)
2.1 Fix the mounting of the solar controller panel.
2.2 Select Lead-Acid or Gel-cell Battery modes.
2.3 Connect the solar panel positive side to the solar controller ARRAY PO with a suitable wire (Be careful DO NOT
short circuit the solar array.)
2.4 Connect the solar panel negative side to the solar controller ARRAY NEGATIVE–with a suitable wire
2.5 Connect the battery positive side to the solar controller BATTERY PO with a suitable wire.
2.6 Connect the battery negative side to the solar controller BATTERY NEGATIVE –with a suitable wire.
Any wiring variation of size or length can affect the LCD meter performance
3. Wire size: - Refer to the “WIRE SIZE” chart below to determine the minimum size wire needed for each connection. When
using heavy stranded wire, you may need to divide the ends into two groups and straddle the screw on the terminal block.

4. Wire type: - It is better using stranded wire instead of solid wire. Stranded wire does not fatigue and cause loose
connections over time as easily as solid wire. Use red wire for (+) and black wire for (–). One 6 AWG wire (stranded) or
two 8 AWG wires are suitable. Better connect the wires to the controller with crimped connectors.

CAUTION: Do not attempt to change the battery type selector switch during charging, otherwise will affect LCD meter
reading.
6. OPERATION
When connection was completed, the charge controller will start charging the battery automatically. The solar controller is
based on three stage charging algorithm, i.e. Bulk charge mode, Constant-voltage mode and Float mode. During charging
period, you can change the select switch to read the battery voltage or charging current from LCD meter at any time.
• Battery condition detect by LED bar-graph. The controller can indicate the battery condition with three states: GOOD,
FAIR, LOW.
• PWM constant-voltage regulation to prevent heating and excessive battery gassing. Pulse charging to restore full battery
capacity.
• Float mode: When the battery was fully charged, the battery voltage will reduce to a lower regulated voltage, in which
maintains the battery at full charged state safely.
