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.
