GFPD-600V Ground Fault Protection Device

Morningstar’s Ground Fault Protection Device (GFPD-600V) increases safety and design flexibility in off-grid and on-grid photovoltaic (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. Morningstar’s GFPD will detect this condition and break the circuit on both the positive and negative legs. Disconnecting both poles ensures interruption of the ground fault current.

• Breaks the PV array during a fault condition.
• Leaves the battery and DC loads grounded under all conditions.
• Eliminates the danger of an ungrounded battery and therefore requires no special labeling at the battery location.
• Audible and visual indications.
• Precision current measurement, not fuses.
• Push-button test circuit.

The GFPD enables system design flexibility. Morningstar designed the GFPD to be easily paired with their world-leading TriStar MPPT Charge Controller during on-site installation. Additionally, the GFPD will work just as well in systems with mixed vendor components.

Morningstar’s GFPD is a superior solution to ground fault protection. With its custom molded equipment ground terminals, installation and troubleshooting are simplified. Furthermore, the GFPD breaks the entire PV array circuit during a fault condition and requires no special labeling on the battery enclosure.
