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.

FAQs

• What is Low Voltage Disconnect (LVD)?
  The LVD/LVDR function of Morningstar controllers is designed to protect system batteries from overdischarge and (to a lesser extent) protect sensitive system loads from low battery voltage. When the battery drops to the LVD threshold, loads connected to the controller are shut OFF to give the batteries time to recover their charge. When the battery voltage rises above the LVDR threshold, loads that were previously disconnected are turned back ON. Low Voltage Disconnect/Reconnect does not affect the controller’s charging ability; charging continues whether in the disconnected state or in the connected state.
