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.
While the latest Generation 3 ProStar shares the outstanding build
quality and familiar form factor as its predecessors, it comes with
new data and lighting control capabilities, a new 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.
