40A Solar Charge Controller (12/24V, PWM)

The 40A Solar Charge Controller is designed for 12V and 24V Lead-Acid, Gel & AGM Deep Cycle batteries. It automatically detects the type of battery used in your set up and is plug-and-play (internal values can be adjusted manually). The 40-60A series of PWM controllers is larger in size than the 10-30A series and includes a metal backplate heatsink.

FEATURES:

• 40A Solar Charge Controller with 3-stage PWM charge management
• Supported battery types: Lead-Acid, Gel, AGM Deep Cycle batteries, 12V and 24V
• Dual USB output ports (5V, 2.5A)- compatible with multiple digital devices
• LCD display – voltage, status, time, load, output, charge & more
• Safe (CE-marked), easy to operate & install
• Metal backplate with heatsink to keep the controller cool

Electronic protection features

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

Wiring steps

1. Screw the adjustment screw anticlockwise until the plates move down

2. Insert the wire into the new opening between the plate and the “top” of the terminal hole, not underneath it

3. Screw the adjuster clockwise. The plate will move upwards, therefore squashing the wire in the terminal hole

Installation steps

1. Connect the system in the exact order: battery, then load, then PV array

2. 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
