The chassis must be grounded through the equipment grounding conductor. The key rule involves the neutral-to-ground bond: Only one bond point avoids parallel paths and GFCI issues. Ungrounded or floating is now common with transformerless inverters, which rely on ground-fault detection interrupters (GFDI) for safety. They ensure the metal components are at the same electrical potential as the Earth's surface. In this blog, we will learn how to ground solar. An inverter can operate without being grounded and will thus be a potential hazard to users as it can cause a nasty, even fatal shock. Understanding and applying the requirements of NEC. In this video, I walk you through the complete process of properly grounding (earthing) your solar hybrid inverter system for safety and durability. This document does not replace any regional, state, provincial, federal or national laws, regulations or standards that apply to the installation, electrical safety.
