Solar Regulators & Accessories

A solar regulator is the brains of your solar setup. It sits between your panels and battery, managing the charge so your battery gets fed properly without being overcharged or damaged. Whether you're running a simple camp setup or a full touring rig, you need one if you've got solar.

We stock both MPPT and PWM regulators. MPPT units are more efficient and squeeze extra power from your panels, especially in less-than-perfect conditions. They're ideal if you're serious about solar and want maximum charge, particularly with larger panel arrays. PWM regulators are simpler and more affordable, perfect for straightforward setups where you're running smaller panels and don't need every last watt.

Most of our regulators handle both lithium and AGM batteries, with programmable charge profiles so you can switch between battery types as your setup evolves. Built-in digital displays show real-time data like volts, amps, and watts, so you always know what's happening. And we've made installation easy with quick-connect plugs and screw terminals included.

When you're choosing a regulator, think about your panel wattage and battery type. A 20A MPPT regulator can handle up to 250-390W of solar depending on your system voltage, while a 15A PWM is suited to smaller arrays. If you're unsure, our team can help you match the right regulator to your folding solar panels or fixed panel setup.

We also stock the accessories you need to get everything wired in, from extension leads to mounting hardware. And if you're building a complete power system, check out our battery range and chargers to round out your setup.
