Description:
The MidNite Solar MNDC-GFP80 is required by the NEC for PV arrays mounted on residential dwelling roofs. It can be used with newer MidNite Solar e-Panel Disconnects and other Panel Mount installations. The MNDC-GFP80 protects wiring and system components by detecting current flow between the solar array and the DC disconnect on grounding conductors such as panel frames, mounts and the bare copper wire that connects everything to the ground rod.
