An MPPT Solar Charge Controller is basically a solar battery charger. It takes the power generated by your solar panel and uses it to very efficiently charge your leisure battery. This  is particularly useful in off-grid solar panel kits and setups with varying sunlight, as it maximizes energy harvest and extends battery life. Whether you're powering a campervan, boat, or off-grid home, an MPPT controller helps you get the most efficient charger from your solar power system.

Components as a category just refer to the building blocks of an electrical system in your van. It may include fuses, connectors, switches, cable, battery monitors, and inverters. Depending on your setup, additional accessories like split charge relays and solar controllers may be needed to optimise your system.

Choosing the right accessories depends on your campervan's specific electrical needs, planned upgrades, and compatibility with existing components. Generally, unless you know specifically what you need, we find it more helpful to consider a more complete solution. You can learn more about this here.
