Xantrex Technology C12 PWM Solar Charge Controller

Description:

The Xantrex C12 PWM Solar Charge Controller is used a 12-amp photovoltaic charge, load, and lighting controller designed for off-grid solar power systems, battery charging applications, and DC load management. Commonly used in RV solar systems, marine installations, remote lighting systems, cabins, telecom sites, and small off-grid renewable energy applications where reliable PWM battery charging and low-voltage disconnect protection are required. Installers and solar technicians use the C12 for battery management, lighting control, and solar charge regulation.

Applications:

The Xantrex C12 controller is used in off-grid solar systems where photovoltaic charging, DC load protection, and lighting automation functions are required. It is commonly applied in remote village lighting, outdoor lighting systems, RV and marine solar setups, telecommunications backup systems, and standalone battery charging systems. The controller supports photovoltaic charge control, DC load control, and dusk-to-dawn lighting functions with adjustable timing modes.
