Electronic protection features
 

• Open-circuit protection
• Short-circuit protection
• Reverse protection
• Overload protection
• Dual Mosfet reverse current protection

Wiring steps
 

• Screw the adjustment screw anticlockwise until the plates move down
• Insert the wire into the new opening between the plate and the "top" of the terminal hole, not underneath it
• Screw the adjuster clockwise. The plate will move upwards, therefore squashing the wire in the terminal hole

Installation steps

• Connect the system in the exact order: battery, then load, then PV array
• Disconnect the system in the reverse order: PV array, then load, then the battery

Notes

• Ensure your battery has enough voltage for the controller to recognize the battery before the first installation
• Keep the controller in a cool & well-ventilated place to maintain good heat dissipation
