The Xantrex C-Series C12 is a 12A PWM controller working as a solar charge controller, DC load controller or automatic lighting controller.
The automatic lighting mode is unique to the C12 within the C-Series, and it switches loads on darkness rather than on voltage. That suits anchor lights, deck lighting or a navigation aid, where the requirement is dusk-to-dawn operation rather than battery protection.
Twelve amps is the smallest C-Series controller, suiting a single panel or a modest array. The C35, C40 and C60 cover larger installations, and only the C40 adds 48V capability.
Charging mode uses three-stage charging with user-definable voltage settings and automatic equalization for supported lead-acid batteries. Optional battery temperature sensing adjusts charging as the bank warms or cools, which matters because the correct voltage moves with temperature. Explore more solar charge controllers.
