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.”
They’re worth it, because they provide the faster power “tracking” that lets us engineer this much power and control into a compact design.
Combined with premium, “over-spec’d” components, this greatly improves control response which guards against system transients, regulation overshoot and overcurrent/overload conditions
Nature do your worst–this controller can take it
If you’ve ever trashed a lesser terminal during an installation, you’ll appreciate some “overkill” here
Allows the surface-mounting of critical components underneath the main board next to the heat sink, which reduces heat travel distance and keeps the controller even cooler
As opposed to cast aluminum, which is less effective in passive cooling applications
“Talks solar” with standard industry language, for system monitoring and cloud connectivity-speaks Modbus, and SNMP (with the EMC-1)
Lithium batteries are expensive and vulnerable to cold temperatures. When it gets close to freezing, the controller backs-off charging to avoid damaging batteries
All-digital calibration for high accuracy, using the same efficient technology found in advanced mobile device
Morningstar’s hallmark MPPT technology precisely seeks and locks onto the true maximum power point quickly and accurately, to ensure the highest output possible from a solar array
When you’ve been in the field installing, you appreciated being able to read a crisp, high contrast display on site
Up to 2 1/2 times longer than some competitors in this class
ProStar is smart enough to monitor and analyze system performance, and alert you when you need to know
Heat is the enemy of all electronics. That’s why Prostar’s critical components are rated to withstand temperatures right up to the boiling point of water (100°C)
Protects the precision electronics inside with an impact strength 30 times greater than the acrylic thermoplastics commonly found on lesser controllers
Just kidding. We’ve never needed them

This short video highlights the ProStar (Gen3) PWM solar charge controller. This device has been upgraded, while maintaining the same quality and form factor of previous models that have been installed in over 100 countries in the world’s harshest environments since 1995. View this video to learn about the new features and capabilities of this product including enhanced custom programming, data logging, communications, and lighting control.
This presentation provides a more in depth overview the ProStar (Gen3) PWM solar charge controller. You’ll see a comparison between the Gen3 and earlier ProStar models concerning meter displays, self-diagnostics, load/lighting control, communications, data logging, certifications, and other features.
enables IP-based networking and internet connectivity for select Morningstar products
prevents current from following any unintended paths during a ground fault
recommended when temperature at the battery and controller differs more than 5°C
programs conditional generator start/stop, high/low voltage alarms, load control and more
enables up to 15 Morningstar products on a single MeterBus network
provides voltage, current and temperature readings up to 10 meters away from system
converts a controller's RJ-11 meter port to a RS-232 serial connector for connection to a PC
converts RJ-11 interface to USB 2.0 interface to allow MS product to communicate with a PC
It’s a recommended best practice to install your product’s latest firmware to ensure access to all up-to-date features, accessory compatibilities, and code modifications. Watch this 5 minute video for instructions on how to download and update ProStar MPPT firmware.
