Description
Ensure superior safety and compliance for your grounded photovoltaic (PV) systems with the Morningstar 600V Ground Fault Protection Device (GFPD). Designed to meet stringent US National Electric Code (NEC) requirements, this innovative GFPD provides highly sensitive ground fault detection and reliable circuit interruption, safeguarding your investment and preventing potential hazards.
The GFPD enables system design flexibility. Morningstar designed the GFPD to be easily paired with the 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.
Key Features and Benefits:
Powered via the PV system’s battery bank – and supports a wide range of voltages (12V, 24V, 36V, 48VDC nominal systems)
Breaks the connection to 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 (per NEC)
Features audible and visual indications/alarms
Performs precise current measurement with no fuses
Built to support both single controller and multiple controller systems
Certifications: CE, RoHS and REACH Compliant; UL Listed; (NEC) 690.5 Compliant for use as a GFPD device
Enhanced Sensitivity and Precision: The Morningstar GFPD offers exceptional sensitivity in detecting stray currents, ensuring rapid and accurate ground fault identification.
Dual-Pole Interruption for Complete Protection: Unlike conventional GFPDs, our device interrupts both the positive and negative legs of the circuit, guaranteeing complete isolation of the ground fault current and maximizing safety.
Maintains Earth Ground Bond: Our unique design preserves the critical bond to earth ground, preventing the battery and DC loads from floating and ensuring consistent system grounding. This is a significant advantage over devices that compromise the earth bond.
Superior Isolation: The GFPD effectively isolates the PV array from the battery and loads, minimizing the risk of damage and maintaining system integrity.
NEC Compliance: Specifically engineered to meet the ground fault protection requirements of the NEC for grounded PV systems, providing peace of mind and regulatory adherence.
Reliable Ground Fault Detection: Detects current imbalances between positive and negative PV conductors, a key indicator of ground fault conditions.
600V Compatibility: Designed for high-voltage PV systems, supporting up to 600V.
Increased System Safety: Prevents unintended current paths and mitigates the risk of electrical shock and fire hazards.
How It Works:
The Morningstar GFPD continuously monitors the current flow between the positive and negative PV conductors. Any imbalance detected indicates a potential ground fault. Upon detection, the GFPD instantly interrupts the circuit on both poles, effectively isolating the fault while maintaining the crucial earth ground connection. This ensures safe operation and protects your valuable equipment.
Why Choose Morningstar’s GFPD?
Traditional ground fault devices may compromise the earth ground bond, leading to potentially dangerous floating voltages. Morningstar’s GFPD provides a safer, more reliable solution by preserving the earth ground while delivering superior ground fault protection. Invest in the Morningstar 600V GFPD for unmatched safety and performance in your grounded PV system.
