One way to earth a solar inverter is to connect it to the grounding system of the building or structure where it is installed. This can be done by using a grounding rod or electrode to create a direct path for electrical currents to flow into the ground.
The AC and DC sides of the inverter are grounded separately. It is important to connect the inverter''s grounding terminal to the grounding electrode system to prevent potential hazards such as ground faults. The inverter’s internal protection circuits will trip in the event of grounding faults, ensuring system and personnel safety.
Most modern grid-tied inverters have integrated grounding terminals for easy connection to the system ground. The AC and DC sides of the inverter are grounded separately. It is important to connect the inverter''s grounding terminal to the grounding electrode system to prevent potential hazards such as ground faults.
As shown in the fig, separate grounding rods are used for individual systems e.g. AC side and DC side. The equipment grounding conductor (EGC) from the main panel and PV arrays are connected to the Ground terminal and Ground bus in the inverter.
