Morningstar’s Ground Fault Protection Device products are built to provide a superior solution to ground fault protection for both off-grid and on-grid PV systems. The GFPD products’ are available in two model versions (GFPD-150V and GFPD-600V) to support 150V and 600V PV system breaker stacks. Morningstar’s GFPD increases safety and design flexibility in off-grid and on-grid PV systems. Ground fault protection is used in electrical systems to prevent current from following any unintended paths during a ground fault. It is critical to detect any stray current and to interrupt (break) the circuit until safe operation can be restored. A current imbalance between the conductors of a circuit indicates a ground fault. When a ground fault is detected, Morningstar’s GFPD breaks the circuit on both the positive and the negative legs and ensures interruption of the ground fault current better than other solutions on the market.
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.
