Ground Fault Protection Device Brochure

Morningstar’s GFPD Solution
• Maintains the integrity of earth bond for baery and loads
• Trips at lower fault current with greater accuracy
• Breaks both conductors in the faulted circuit and completely isolates PV source circuits
• Does not require an extra warning label at the baery bank as per U.S. Naonal Electric Code requirements
• Provides design exibility to meet a wide range of conguraons:
• Posive and negave ground
• Large and small arrays
• Makes it easier to locate and troubleshoot ground faults
• Powered via the PV system’s baery bank
• Equipped with both visual and audible alarms
• Built to support both single controller and mulple controllers systems:
• Morningstar’s GFPD will only shut o aected controllers, while maintaining the system earth bond.
• All loads will connue to operate safely with the baery remaining bonded to ground.
• Mulple controllers and GFPDs can be added on an as-needed basis.
