PWM Solar Charge Controllers

Reliable PWM Solar Charge Controllers for Off-Grid Systems

Equip your caravan, RV, or 4WD with a dependable pulse width modulation (PWM) solar charge controller. Designed to regulate the power flowing from your solar array to your battery bank, these controllers prevent overcharging and help maximise overall battery lifespan. PWM technology provides a highly durable, cost-effective solution for straightforward 12V, 24V, and 48V off-grid electrical systems where the nominal solar panel voltage closely matches the battery bank voltage.

Our carefully selected range features industry-leading products from Victron Energy and Morningstar, spanning from compact 4A and 5A units right up to robust 30A regulators. Whether you are maintaining a small starting battery on a boat or keeping your deep cycle system topped up in a camper trailer, these solar regulators deliver consistent charging performance without the need for complex programming. By connecting the solar input directly to the battery with high-frequency pulses, PWM controllers efficiently manage the absorption and float stages of the charging cycle.

Key Features of Our PWM Controller Range

• Versatile Capacity Options: Choose from 5A, 10A, 20A, and 30 amp solar charge controllers to match your specific off grid solar panels and daily energy requirements.
• Integrated Display & USB: Select Victron BlueSolar models feature intuitive LCD screens for real-time monitoring and built-in USB ports to directly charge your portable electronics.
• Dual Battery Support: Manage and charge two independent battery banks simultaneously with specialised Victron DUO models, which are perfect for motorhomes balancing engine and house batteries.
• Automated Load Control: Built-in load output functionalities on specific models allow you to automatically manage lighting systems or small DC loads, preventing deep battery discharge.
• Advanced Safety Protections: Experience peace of mind with reverse polarity, short circuit, and over-temperature protections engineered directly into the unit.

Common Use Cases for Caravan, RV, Marine, and Off-Grid Shoppers

PWM solar charge controllers are incredibly practical across a wide variety of mobile and remote applications. For 4WDs and weekend campers, a 10A or 20A PWM regulator paired with a portable solar setup provides a lightweight, space-saving way to keep a 12V fridge running smoothly. In marine environments, a compact Morningstar SunGuard is the perfect addition for trickle charging a boat battery while moored, ensuring your vessel is always ready for the water.

If you are upgrading a commercial vehicle or truck with a single roof-mounted panel, a 24V PWM controller offers straightforward integration to keep auxiliary tools and equipment powered up. Similarly, off-grid sheds or tiny homes setting up dedicated 48V lighting circuits often rely on higher-voltage PWM models to maintain system stability efficiently. To complete your setup, ensure you explore our range of compatible solar controller accessories to streamline your wiring and mounting process.
