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.

The ViewStar Series Controller is designed based on advanced PWM charging technology, and is suitable for off-grid solar applications. With a range of 0-100%, it can charge the battery quickly and safely under almost any condition of the solar photovoltaic system. It protects the battery from becoming over-charged and over-discharged. The charging process has been optimized to provide for longer battery life and improved system performance. The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults.!

Please Note: These are Negative Ground Controllers. If grounding is necessary, it must be completed on the negative line. If the controller is to be used on a vehicle which has battery positive on the chassis, loads connected to the controller must not have an electrical connection to the vehicle body.
