Morningstar GFPD-150V 150 Volt Ground Fault Protection Device

GFPD-150V 150 Volt Ground Fault Protection Device

Morningstar's Ground Fault Protection Device (GFPD) Family, Models GFPD-150V and 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.

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.

  • 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.
  • Certifications:
    • CE, RoHS and REACH Compliant;
    • UL 1741 and CSA C22.2 Np. 1-7.1-01 Listed
      • GFPD-150 us UL-489 Listed
    • Meets EMC Directives(Immunity, Emissions, and Safety)
    • FCC Class B Part 15 Compliant
    • NEC 690.5 Compliant for use as a GFPD device
