Instructions:

Wiring:

• Unscrew the adjustment screw anti-clockwise until the plates move downward.
• Insert the wire into the opening between the plate and the top of the terminal hole, avoiding placement underneath.
• Screw the adjuster clockwise, causing the plate to move upwards and secure the wire in the terminal hole.

System Connection:

• Connect in the following order: battery, load, PV array. The system will show 1 ,if it detects 12V battery, 2 if it detects 24V battery.
• Disconnect in reverse order: PV array, load, battery.

Note:

• Ensure sufficient battery voltage for controller recognition before initial installation.
• Maintain proper heat dissipation by placing the controller in a cool, well-ventilated location.
• Ensure adequate battery voltage for controller recognition during initial installation.
• Minimize cable length to reduce energy loss.
• Only connect solar modules to the charge regulator; do not connect other charging sources.

Package includes:

• 1 x 20A 12v/24v Solar Charge Controller
• 1 x User Manual
