12 Volt 20 Amp Solar Charge Controller

Posted on Mar 7, 2013

The SCC3 is a solar charge controller, it`s 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, an equalize function for periodic overcharging, and automatic temperature compensation for better battery charging over a wide range of temperatures. The SCC3 rev C design is able to handle reverse polarity connection of both the battery and photovoltaic panel.
