Morningstar’s Commitment To Technical Support

Over 90% of those surveyed rate Morningstar Technical Support as either “above average” or “really exceeding expectations.”  In fact, they rate our Technical Support better than any other charge controller brand.

Unlike other companies that have outsourced their support, we have a US-based team of full-time professionals with over a half-century of combined renewable energy experience.  Technical Support is all they do, and they do it very well.  Take our customers’ word for it.

They’re dedicated to providing fast resolution on any issues, including product registrations, warranty claims, and access to datasheets, manuals, technical documents, firmware updates and other information.   And “fast resolution” means something to them.  With an average response time of less than four business hours they’re setting the standards for others to try and match.

Let them know how they can help you, especially if you can’t find the information you need in our Support Library and Answers to FAQs on this page.
