The ProStar solar charge controller has been the leading mid-range pulse width modulation (PWM) controller since 1995. With over 350,000 units installed in the harshest environments in over 100 countries, the ProStar has developed a strong reputation for reliable performance. This third generation ProStar maintains the same quality and form factor as previous models, while offering new data, lighting control, graphical interface, and protection features to better meet the needs of off-grid solar applications.
The PS-15 is perfect for small to mid-size solar arrays. Once it's set up, it operates autonomously, without any need for user input. These units are great for off-grid homes, cabins, remote communications sites, water pumping systems, and more.
