Since the introduction in 1996, more than 1.5 million SunSaver Controllers have set the standard for reliability and performance in demanding oilfield and mining installations in nearly 90 countries around the globe. Today, SunSaver is the world’s leading small solar controller for industrial and consumer markets, proven in mission critical applications where failure is simply not an option.
This third generation SunSaver brings over two decades of advances in software and electronics to the same rugged, hardened design that made the original famous. Own both a legend and the latest in a single product.
“This is the only one I’d use…it’s the one I wish I bought first”
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 5 minute video highlights the ProStar MPPT solar charge controller’s circuit board that differentiates it from other brands. In addition to the capacitors, inductors, processors, surge protectors, and other over-spec’d internal components, the quality of the controller’s heat sink and outer casing is also addressed. The video concludes with mention of features and capabilities related to communications, datalogging, lithium battery charging, and high quality and reliability.
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.

The schematic diagram above, illustrates how the ProStar MPPT regulates power to batteries and a direct current (DC) load in an off-grid system.
The schematic diagram above, illustrates how the ProStar MPPT regulates power to batteries and an alternating current (AC) load in an off-grid system. This diagram is very similar to the DC load diagram above it except an inverter has been added.
