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, ProStar sets the standards in performance and reliability for the rest of the solar industry.

The Generation 3 ProStar shares the outstanding build quality and familiar form factor of its predecessors and adds data and lighting control capabilities, a graphical interface, and advanced protection features that meet the needs of today’s most demanding off-grid solar applications. ProStar provides both “the legend and the latest” in a single new product.

“…you get what you pay for, and this one is worth every penny…count on Morningstar.”
