General Information
A photovoltaic charge controller or regulator is a device that prevents solar panels from over charging your batteries by regulating the current flowing from your solar panels to the battery bank. When your batteries are fully charged, the controller stops the flow of current or slows it to a slow trickle. Connecting your solar array to your batteries without a controller seriously risks damaging your batteries and potentially causing safety problems. Charge controllers are rated and sized according to the systems they protect and to the amount of current flowing from your solar array.
Most common are 12, 24 and 48-volt controllers. Amperage ratings range from 1 amp to over 100 amps.
For safety reasons it is best to oversize your controller by at least 25%.
For example, if your 12-volt system has four solar panels rated at 4.0 amps each, total output would be 16 amps. Adding 25%, you would need at least a 20- amp controller.
There is no problem going with a larger controller other than additional cost and it’s something you may want to consider if you think you may be adding more solar panels in the future.
Other than protecting your batteries from over charging, there are several other features that should be included in your controller.
A few of these options are:
• Reverse Current Leakage Protection - This keeps current from flowing backward from your
batteries to your array.
• Low Voltage Disconnect - This reduces damage to your batteries by avoiding deep
discharges.
• System Monitoring - meters, indicating lights and/or warning alarms.
• Temperature Compensation - The charging voltage is adjusted to the temperature if your
batteries are not in a climate-controlled space.
Remember Always Use Proper Sized Wiring and Connectors.

| C12 Charge Controller Description
12 Amp 3-stage Solar Charge, DC Load and Auto Lighting Controller The C12 charge, lighting, or load controller is uniquely sophisticated. As a charge controller, it features three-stage charging, user definable voltage parameters, and automatic equalization. Standard in the C12’s load control circuitry are field adjustable low voltage disconnect and reconnect points, along with a five minute low battery disconnect warning. The C12 also functions as a lighting controller. Lighting run time is adjustable from 2 to 8 hours or can be set from dusk to dawn operation. It is used worldwide in a variety of applications, including remote village lighting systems and automatic outdoor lighting in Africa, Latin America, and Asia. An optional battery temperature sensor ensures precise battery charging regardless of battery temperature fluctuations.
