People are asking

What does a solar controller do in a campervan system?

A solar controller (charge controller) regulates the voltage and current from solar panels to safely charge your leisure battery. Without one, solar panels would overcharge and damage the battery. The Projecta 15A controller suits panels up to around 200W on a 12V system.

Is this a PWM or MPPT solar controller?

The Projecta Solar Controller 15A is a PWM (Pulse Width Modulation) controller, which is a reliable and cost-effective option for smaller systems. If you have a larger panel array or want maximum efficiency, consider the Projecta PM335C which includes a built-in 30A MPPT controller.

What size solar panel suits the Projecta 15A controller?

At 15A on a 12V system, the controller handles up to around 180W of solar input. A single 120W or 160W panel is an ideal match. Exceeding the rated input current will damage the controller, so always check panel short-circuit current (Isc) against the controller spec.
