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.
Any wiring variation of size or length can affect performance of the charge controller

OPERATION
Once properly mounted and connected the charge controller will start charging immediately given
adequate solar power. The 12 Volt 10 Amp Solar Charge Controller is based on a three stage
charging algorithm, Bulk Charge Mode, Constant Voltage Mode and Float Mode.
• PWM constant-voltage regulation to prevent heating and excessive battery gassing. Pulse
charging restores 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.
NOTE: The Solar Charge Controller will not initiate charge cycle if battery voltage is less than 4.0
Volts.
