Solar Light Control Board PCBA 3.2V–15V | Auto Dusk-to-Dawn

Solar Light Control Board – Automatic Dusk-to-Dawn Switching

Keep your outdoor solar lights running effortlessly with this compact Solar Light Circuit Control Board (PCBA). Designed for courtyard lamps, lawn lights, wall lights, landscape fixtures, and other low-power solar LED products, this controller automatically senses ambient light — switching your lights on at dusk and off at dawn without any manual intervention.

Available in a convenient 1-pack or 3-pack, each board comes pre-fitted with wires for fast, straightforward installation into your solar lighting project or repair job.

Key Features

• Wide Voltage Compatibility: Works with battery voltages from 3.7V to 15V — suitable for single-cell lithium packs through multi-cell configurations.
• Automatic Light Control: Built-in photosensitive control — no daylight operation, seamless activation in darkness.
• Solar Panel Input: Accepts solar panel voltage = battery voltage × 1.5 (e.g. a 3.7V battery pairs with a ~5.5V panel).
• Max Input Current: Up to 5A — handles most standard solar garden light panels.
• Max Output Current: Up to 3A — drives LED strings and low-power lamps with ease.
• Pre-Wired Connections: Ready-to-connect leads for the solar panel, battery, and LED load — no soldering required for basic install.
• Compact Form Factor: Just 3.8 × 1.5 cm — fits neatly inside lamp housings and enclosures.
• Versatile Use: Compatible with solar lawn lamps, column lamps, wall lamps, landscape decorative lights, and similar low-power solar products.

Frequently Asked Questions

Q: What types of solar lights is this control board compatible with?

A: This solar light PCBA controller is compatible with a wide range of low-power solar outdoor lights, including solar lawn lamps, column lamps, wall lamps, courtyard lights, and landscape decorative lights. It supports battery voltages from 3.7V to 15V, making it suitable for single-cell and multi-cell lithium battery setups.

Q: Does this board automatically turn the light on at night?

A: Yes! The board uses a built-in photosensitive (light-sensing) control circuit. When the solar panel detects low light levels at dusk, the output automatically activates your connected LED light. During daylight, the panel keeps the circuit off and charges the battery instead.

Q: Does this board have overcharge or over-discharge protection?

A: No — this PCBA does not include built-in overcharge or over-discharge protection. It is essential to use a battery that has its own dedicated protection board to safeguard against battery damage.

Q: Do I need to solder this board to install it?

A: No soldering is required for a standard installation. Each board comes pre-fitted with wires for the solar panel input, battery connection, and LED load output, making it straightforward to connect to your solar light system.
