AC Grounding

The AC input and AC output circuits are isolated from the enclosure and system grounding, if required

by Section 250 of the National Electrical Code, ANSI/NFPA 70, is the responsibility of the installer.

PV Grounding

The Photovoltaic System Grounding shall be installed per the requirements of Sections 690.41

through 690.47 of the National Electrical Code, ANSI/NFPA 70 and is the responsibility of the

installer.

The grounding conductor in the framework of the PV array must be connected to the PV grounding

conductor and the DC grounding conductor (see Section 5.3"Connection Area of the Sunny

Boy",page32). The cross-section of the grounding conductor corresponds to the cross-section of the

largest conductor in the DC system.

DC Grounding Conductor

A DC grounding conductor may be required by the Authority Having Jurisdiction (AHJ). Use the

terminal block for the PV grounding conductor and DC grounding conductor (see Section

5.3"Connection Area of the Sunny Boy",page32).

The AC outputs and the neutral conductors are not bonded to ground

The Sunny Boy must be connected to the AC grounding conductor of the power distribution grid

via the ground terminal (PE) (see Section 5.3"Connection Area of the Sunny Boy",page32).
