Morningstar: A Consistent and Dependable Supplier of Off-grid Solar Charge Controllers & Inverters for Over 25 Years.


With well over 4 million products sold in over 100 countries since 1993—functioning in some of the most extreme environments and mission-critical applications in the world—Morningstar Corporation can truly claim to be “the leading supplier of solar charge controllers and off-grid inverters.”  That success is why Morningstar has had staying power and stable management for over 30 years, along with the lowest employee turnover rate— in an industry where many companies come and go.

Morningstar’s main advantage can be summed up in two words: employee ownership. Our own reputations literally ship with each product we make, so we continually strive to keep our quality and reliability at an industry-record high. This is how we’ve earned the lowest hardware failure rate in the industry.  Employee ownership is the secret behind our industry-leading quality and value—and why those words are not just a cliché or catch-phrase, but actually mean something at Morningstar.

It’s not a buzzword for us, but fact-based on over a quarter-century of industry “firsts,” evidenced by a series of advanced technology and manufacturing process patents awarded to us.  Morningstar has over 20 patents and a dozen trademarks associated with thermal engineering, mechanical design, charging and control, advanced electronic topologies, safety systems, and more.

Research and Development

We invest in the best R&D talent and resources available, with a ratio of designers and engineers unparalleled in our segment of the renewables industry.  We maintain 35kW of photo-voltaic solar at our facility for real-world testing, research, and evaluation.


We’ve pioneered smarter digital design for solar components, for faster, more agile processing on-board.  This allows us to extract all the performance possible from our hardware.  On the hardware side, we use advanced thermal engineering to eliminate cooling fans—the weak link in competitors’ products. Finally, our internal electronics are laid out for performance and longevity instead of economics—because, as employee-owners, we can design for the long-term instead of a bottom line, in order to achieve the industry’s lowest hardware failure rates. Watch our product videos below to find out why Morningstar is considered to be “the charging experts”.


ProStar MPPT



Another word not used lightly at Morningstar.  With our design and internal engineering excellence as a starting point, we could get higher performance than our competitors if we settled for the “good enough” components that they use. Instead, we go a lot further by using better components than theirs, and build those components into our products using an advanced, fully ISO 9001 factory.  That’s why most of the Morningstar products built since 1993 are still in use.


Morningstar’s products have been recognized in international solar markets as the most advanced and highest-quality products available. Our products exceed all other PV controllers & inverters for protection against extreme environments, corrosion, lightning surges and harsh ambient operating temperatures (common to remote PV systems)—all while delivering more than twice the industry’s average operating life.

Our advanced PWM & MPPT solar charge controllers deliver extended battery capacity & life, lower overall system costs and maximum energy harvest. Our simple-to-use products & customer-focused support includes multi-lingual product documentation, detailed operation/installation manuals, phone & web-based tech support as well as a variety of user & installation friendly product features.

Tools and Facilities

We can quickly and cost-effectively model, plan, construct and build our ideas, with a team capable of working through mechanical & thermal designs and simulations, build advanced prototypes (using metals & plastics), and design on-site printed circuit board layouts.  Our dedicated engineering center has its own advanced R&D facilities, test lab, EMI and environmental chambers, and full-thermal modeling tools including 3D CAD Software for mechanical & thermal design and product simulation. Our advanced testing lab has an array of scopes, analyzers, and diagnostic equipment as well as on-site printed circuit board layout facilities for faster, in-house product development.

Distribution Channels

Supporting our global distribution customer network has been our #1 priority for over 25 years.  Morningstar’s products are marketed through highly qualified distributors in over 100 countries. Our authorized distributors are typically the leading solar distributors in their respective country. They are a vital part of the Morningstar team and have become our long-term business partners.
