Xantrex C-Series Solar Charge Controller – 12A – C12

The Xantrex C-Series C12 is a compact and reliable 12-amp PWM solar charge controller designed for small off-grid solar systems, RVs, marine installations, and portable solar setups. It safely regulates solar charging to protect batteries from overcharging while maximizing battery life and system efficiency.

Featuring three-stage battery charging and support for flooded, AGM, and gel batteries, the C12 delivers dependable performance in simple solar applications. Like other controllers in the Xantrex C-Series, it can be configured as a solar charge controller, load controller, or DC diversion (dump load) controller, offering flexibility for a wide range of low-power renewable energy systems.

With its durable aluminum enclosure, passive cooling design, and proven reliability, the Xantrex C12 is an excellent choice for small cabins, boats, RVs, and backup solar power systems.
