Morningstar Corporation Morningstar Corporation GFPD-150V TriStar Ground Fault Protection Device for 150V controllers

Morningstar's Ground Fault Protection device provides a code-compliant solution for adding ground fault protection to off-grid and on-grid PV systems. The GFPD-150V works with all 150V TriStar controllers. For 600V TriStars use the GFPD-600V. The GFPD detects and interupts ground faults in the PV system. Morningstar's GFPD will detect a current imbalance between conductors in a circuit and will break both positive and negative legs once a ground fault is detected.
