Victron 12/24V 10A BlueSolar PWM-Light Solar Charge Controller

Victron BlueSolar PWM-Light Solar Charge Controller: Reliable 12/24V Regulation for Off-Grid Systems

Efficient PWM Charging with Integrated Load Control

The Victron BlueSolar PWM-Light 10A offers a straightforward, dependable solution for managing solar energy in small to medium off-grid installations. Designed for 12V and 24V battery systems, this controller uses pulse width modulation (PWM) technology to deliver a three-stage charge cycle—bulk, absorption, and float—that helps maintain battery health and extend service life. Unlike generic controllers, the BlueSolar PWM-Light includes a dedicated load output with low voltage disconnect, protecting your batteries from deep discharge damage while powering DC loads directly.

With automatic system voltage detection, the unit adapts to your battery bank without manual configuration, reducing setup time and the risk of incorrect settings. The integrated two-digit seven-segment display provides clear status information and allows quick adjustment of the load output timer, making it a practical choice for lighting control, water pumps, and other timed DC applications.

Built-In Protection for Demanding Environments

Off-grid systems face unpredictable conditions, from voltage spikes to wiring faults. The BlueSolar PWM-Light incorporates multiple layers of protection to safeguard your investment:

• Battery reverse polarity protection via a fuse prevents damage if battery connections are accidentally reversed.
• Output short circuit and overload protection automatically disconnects the load to prevent wiring damage or fire risk.
• Over-temperature protection reduces charge current if the controller exceeds safe operating limits, ensuring reliable performance in hot Australian conditions.

These features reduce the risk of system downtime and costly component replacements, giving you confidence in remote or unattended installations.

Simple Lighting Control with Day/Night Timer

For applications like pathway lighting, signage, or security lights, the built-in lighting control function offers a single programmable timer. The controller can automatically switch loads on at dusk and off after a set number of hours, or provide dusk-to-dawn operation. This eliminates the need for separate timers or photocells, streamlining your system design and reducing wiring complexity.

Key Features at a Glance

• Automatic 12/24V system voltage detection for flexible installation
• Three-stage PWM charging (bulk, absorption, float) to optimise battery life
• Load output with manual control and low voltage disconnect to protect batteries
• Integrated day/night timer for automated lighting control
• Two-digit seven-segment display for status monitoring and timer configuration
• Comprehensive protection: reverse polarity, short circuit, overload, over-temperature
• Common positive grounding compatible with many existing systems
• Compact IP20 design for indoor or protected mounting (70 x 133 x 33.5 mm)
• Terminal size 5 mm² / AWG10 for secure, low-resistance connections
• Wide operating temperature range: -20 to +50°C at full load

Where the BlueSolar PWM-Light Excels

This controller is particularly well suited to smaller off-grid setups where simplicity and reliability are paramount. Typical applications include:

• Caravans, camper trailers, and RVs needing a compact, easy-to-install solar regulator
• Remote cabins or sheds powering basic lighting and DC appliances
• Solar-powered water pumps or ventilation fans with timed operation
• Marine and boat systems requiring a corrosion-resistant, low-self-consumption controller
• Backup power systems for security cameras, electric fences, or gate openers

With a self-consumption of less than 10 mA, the BlueSolar PWM-Light draws minimal power from the battery when no solar energy is available, preserving stored energy for your loads.

Designed for Australian Conditions

Victron’s engineering ensures the BlueSolar PWM-Light handles the temperature extremes and high UV exposure common across Australia. The controller’s conformal-coated circuit board resists moisture and dust, while the robust terminal block accepts up to 10 AWG (5 mm²) cable, allowing for secure, low-loss connections even in high-vibration environments like vehicles and boats.

Note: For 12V systems, use 36-cell solar panels; for 24V systems, use 72-cell panels or two 36-cell panels in series. This ensures the maximum solar voltage (28V for 12V systems, 55V for 24V systems) is not exceeded.

Take Control of Your Off-Grid Power

Whether you’re upgrading an existing solar setup or building a new system from scratch, the Victron BlueSolar PWM-Light 10A delivers the essential features you need without unnecessary complexity. Its proven PWM charging algorithm, integrated load control, and robust protection make it a smart choice for anyone seeking a dependable solar charge controller for 12V or 24V applications.
