Victron Energy BlueSolar PWM Light Charge Controller (12V / 24V / 10A)

The Victron BlueSolar PWM-Light 12/24V 10A is a compact and cost-effective PWM solar charge controller designed for small off-grid solar systems, battery maintenance applications, campervans, caravans, boats, remote lighting installations, and standalone solar-powered equipment. It automatically detects 12V or 24V battery systems and manages battery charging using a proven three-stage charging algorithm to maximise battery life and charging efficiency.

The controller includes a dedicated load output with low-voltage disconnect protection, preventing excessive battery discharge by automatically disconnecting loads when battery voltage becomes too low. It also incorporates a lighting control function with timer settings, making it particularly suitable for solar-powered lighting systems and remote installations.

Technical Specifications

Charging & Load Management

Three-Stage Battery Charging

The controller automatically performs:

1. Bulk charging
2. Absorption charging
3. Float charging

This ensures batteries receive a full charge while reducing the risk of overcharging and extending service life. The charging profile is fixed and not user-programmable.

Low Voltage Disconnect

The built-in load output protects batteries by disconnecting connected loads before damaging deep discharge can occur. This feature is especially useful for lighting systems and small DC appliances.

Lighting Control Function

The controller can automatically switch connected lighting loads based on sunset and sunrise timing, with configurable timer settings for nighttime operation.

Protection Features

• Reverse battery polarity protection
• Reverse solar panel polarity protection
• Overload protection
• Short-circuit protection
• Low battery protection
• Electronic load management
• Automatic fault recovery.

Recommended Solar Panel Size

Typical maximum solar array sizes:

PWM controllers perform best when the panel's nominal voltage matches the battery voltage. For larger arrays or improved energy harvest, Victron SmartSolar MPPT controllers are generally recommended.

Ideal Applications

• Campervans
• Caravans
• Boats
• Garden buildings
• Solar lighting systems
• Remote monitoring stations
• Small off-grid solar systems
• Security lighting
• Battery maintenance systems
• Agricultural solar installations.
