The main advantage of PWM is that power loss in the switching devices is very low. When a switch is off there is practically no current, and when it 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 the needed duty cycle.
This solar system controller adopts the most advance digital techniques and operates fully automatically. The Pulse Width Modulation (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-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.
Please Note: These are Positive Ground Controllers. If grounding is necessary, it must be completed on the positive line. If the controller is to be used on a vehicle which has battery negative on the chassis, loads connected to the controller must not have an electrical connection to the vehicle body.
