SCC3 - 12 Volt 20 Amp Solar Charge Controller
The SCC3 is a solar charge controller, its function is to regulate the power flowing from a photovoltaic panel into a rechargeable battery. It features easy setup with one potentiometer for the float voltage adjustment and an equalize function for periodic overcharging. Automatic temperature compensation optimizes battery charging over a wide range of temperatures. The SCC3 is able to handle reverse polarity connection of both the battery and photovoltaic panel. The design goals of this circuit were efficiency, simplicity, reliability and the use of field replaceable parts. The circuit has been designed to be radio-quiet, which makes it suitable for ham radio applications. A medium power solar system can be built with the SCC3, a 12V (nominal) solar panel that is rated up to 20 amps, and a lead acid or other rechargeable battery that is rated from 500 milliamp hours to 400 amp hours of capacity.
