Xantrex Technology C12 PWM Solar Charge Controller

The Xantrex C12 PWM Solar Charge Controller is a 12-amp photovoltaic charge, load, and lighting controller designed for off-grid solar power systems, battery charging applications, and DC load management. It is commonly used in RVs, marine installations, remote lighting systems, cabins, telecom sites, and small renewable-energy setups, delivering 12 V DC operation with three-stage charging (Bulk, Absorption, Float) and both automatic and manual equalization to optimize battery health. The unit also provides dusk-to-dawn lighting functions with adjustable timing modes, DC load control with auto reset up to 12 A, and a compact powder-coated steel enclosure (6.5 × 4.3 × 1.6 in, ~2.0 lb) that uses #10 AWG stranded wiring; its technical specs include a maximum PV open-circuit voltage of 25 V, a PV-to-battery voltage drop of up to 0.3 V, a minimum operating voltage of 6 V, and indoor vertical wall mounting capability with NITE-LITE mode as an operating mode.
