Solar inverter phase line grounding

The AC side connects inverter output to the main service panel. This document does not replace any regional, state, provincial, federal or national laws, regulations or standards that apply to the installation, electrical safety. . Grounding a solar inverter is referred to as connecting the metal casing of the inverter to the earth, creating a path for extra electrical current to be safely discharged. Bonding ties all metallic components together so no dangerous voltage difference exists between racks, frames, or chassis. An ungrounded inverter will contain live points, which, when touched, will send a current through your body to the earth. Your body has completed the loop to earth. . Solectria prepared this document to aid the PV developers with the design of grounding bank in order to be compliant with the effective grounding requirements of utilities that accept the IEEE P1547.
