24V Solar Charge Controllers

High-Efficiency 24V Solar Charge Controllers

Harness the full potential of your off-grid power system with a reliable 24V solar charge controller. Designed to safely regulate the voltage and current flowing from your 24V solar panels to your battery bank, these precision regulators prevent overcharging and significantly extend battery life. Whether you are outfitting a heavy-duty truck, a marine vessel, a large touring caravan, or an off-grid tiny home, a 24 volt solar controller ensures your energy setup operates safely and efficiently.

Premium MPPT Regulators for 24V Systems

Our collection features advanced MPPT (Maximum Power Point Tracking) technology, which converts excess solar panel voltage into usable charging current, delivering up to 30% more power than traditional PWM options. We stock industry-leading brands engineered for rugged conditions, including highly efficient Victron SmartSolar and BlueSolar units, robust Enerdrive controllers with built-in displays, and specialised Genasun voltage boost regulators.

For smart power management, select Exotronic and Victron controllers offer integrated Bluetooth connectivity, allowing you to monitor real-time solar yield, review historical data, and check battery status directly from your smartphone or tablet.

Key Features of Our 24V Controller Range

• Advanced MPPT Technology: Rapidly adapts to changing light conditions for maximum energy harvest in partial shade.
• Comprehensive Battery Compatibility: Configurable charge profiles tailored for AGM, Gel, and lithium-ion batteries.
• Remote Monitoring & Control: Bluetooth connectivity and networking ports for seamless system integration.
• Durable Construction: Built to withstand harsh off-road vibrations and marine environments, with selected models offering waterproof enclosures.

Sizing and Selection Tips for 24V Controllers

Choosing the correct 24V charge controller ensures optimal performance and prevents system damage. Follow these sizing guidelines to match a regulator to your specific setup:

1. Calculate Your Solar Array's Maximum Current: Divide your total solar panel wattage by your 24V nominal battery voltage. For example, a 600W solar array dividing into 24V yields roughly 25A. A 30A MPPT controller would provide a safe operating margin.

2. Check the Maximum PV Open Circuit Voltage (Voc): Always verify that the combined open-circuit voltage of your solar panels (especially when wired in series) does not exceed the controller's voltage limit. Victron models indicate this in their names, such as "100/30" (100V maximum PV input, 30A maximum output).

3. Consider Voltage Boost Requirements: If you are charging a 24V battery bank from a lower voltage solar panel (such as a compact 12V panel used where roof space is limited), you will need a specialised voltage boost controller, like the Genasun 24V models in this range.

4. Plan for Accessories and Networking: If you plan to expand your system with smart displays or temperature sensors, ensure your controller has the right communication ports. Reviewing our solar controller accessories can help complete your installation.
