Other brands survive harsh conditions. Morningstar thrives in them.

With more than 25 years of experience and well over four million products in over 100 countries – most of them still in operation – Morningstar has truly earned its reputation for building the “world’s leading solar controllers.” At Morningstar, the word “reliability” means a lot more than a marketing adjective. Morningstar’s employee-owned culture works hard to maintain the lowest hardware failure rate in the industry, because our own reputations literally ship with every product.

That’s why system designers of the most mission-critical solar energy installations around the world insist on Morningstar components, and why you should too on your next project. From mineral mines in South America to telecom repeater stations in Canada, from gas wells in the Middle East to mountain peaks in Nepal, Morningstar technology and legendary quality make the difference between success and failure – and make renewable energy a practical, cost-effective, and long-term solution.

  1. MorningStar SunGuard-4

    This is the second unit I have put in service. They work very well, I am using them with 10 watt solar panels. They keep the batteries charged and never over charge them. There is very little voltage drop across the unit when the sun is shining. When there is no sun, the spec indicates there is only 0.006 amp reverse current though the unit. You don't need a diode
