With the M250, the DC circuit is isolated and insulated from the ground, so no ground electrode conductor (GEC) is required for the microinverter. A ground fault protection (GFP) is integrated into the microinverter. The M250 microinverter is located under each array of the Suniva solar panels. You can't see any cable lines because everything is run through the attic and out the side of the house to the electrical boxes. These have an "industry-leading warranty", up to 25 years.
