C12 Charge Controller, 12A, 12V
Xantrex
C12 - Small System Charge or Lighting or Load Controller
Reliable Controller Technology
The C12 is the most advanced small-system solar charge, lighting, or DC load controller available on the market today. Intelligent microprocessor control and feature packed design brings unsurpassed reliability to even the smallest PV systems.
Product Features
The circuitry comes standard with field-adjustable low voltage disconnect and reconnect points, and a low battery disconnect warning.
Silent, pulse width modulated (PWM), high efficiency operation.
Easy to read, front panel status LED.
Automatic overload protection (in both active and passive modes).
PV array short circuit and reverse polarity protection.
Backed by a two-year warranty.
Optional plug-in remote temperature sensor for increased battery performance.
Solar Charge Controller Features
Three-stage battery charging, user-definable voltage parameters, and automatic equalization.
Selectable settings for flooded lead acid, gel, or absorbed glass mat batteries.
12 VDC array operation.
As a DC Load Controller
Low voltage disconnect warning system.
Field adjustable set points (automatic low and high voltage disconnect).
As an Automatic Lighting Controller
Automatic day and night detection circuitry.
Adjustable run duration from 2 to 8 hours or “dusk to dawn” operation.
