Renogy PWM Dual Battery Charge Controller;

Description
The main advantage of Pulse Width Modulation (PWM) is that power loss in the switching devices is very low. When a switch is off, there is practically no current.
When the device is on, there is almost no voltage drop across the switch. Power loss, being the product of voltage and current, is thus in both cases close to zero.
PWM also works well with digital controls, which, because of their on/off nature, can easily set to the needed duty cycle. This solar system controller adopts the most advance digital techniques and operates fully automatically.
The PWM battery charging can greatly increase the lifetime of your battery and has various unique functions and quite easy to use features.
The Renogy PWM10/20CC-DB features dual battery charging capability making it great for RVs, caravans, and boats. With its advanced PWM charging technology, your batteries will be protected from discharging and over-charging.
