3-24V 10A Solar Panel and Lamp Control Module

3-24V 10A Solar Panel and Lamp Control Module

The 3-24V 10A Solar Panel and Lamp Control Module is a circuit designed to efficiently manage LED power from a rechargeable battery and a solar panel. By automatically switching between solar panel and battery power, it provides reliable lighting even when sunlight is not available.

This module is especially ideal for standalone outdoor lighting systems such as gardens, signs, security lighting, and DIY solar energy projects.

The 3-24V automatic lighting control module board detects darkness by monitoring the solar panel voltage; When the light dims, the panel voltage drops and automatically turns on the LED output.

Notes Before Use

• Do not connect the circuit output to amplifier circuits or incompatible devices.
• The battery must be equipped with a protection circuit to prevent overcharging or overdischarging; This may damage the battery.
• The output protection current can be set within a specific range according to application requirements.
• All batteries used must be equipped with a protection board to ensure their safety and durability.

Features

• Photoresistor-free control technology: No external light sensor required.
• Automatic charging and lighting: Charges during the day and activates lighting in the dark.
