How do you ground a solar inverter?

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.

Where is the grounding point of a PV inverter connected?

The grounding point of the inverter is connected onwards to the grounding system or grounding electrode of the residential facility or building (see figure below). 15) PV circuits having 30V or 8A more shall be provided with a ground-fault protection device (GFPD).

How does a PV inverter work?

This allows the EGC of the PV circuit to be connected to the grounding point provided by the inverter, eliminating the need for a separate DC grounding system. The grounding point of the inverter is connected onwards to the grounding system or grounding electrode of the residential facility or building (see figure below).

Do inverters need to be grounded?

If there is no suitable grounding connection point, then the grounding wire from the inverter must be connected to the negative terminal of the battery bank for off-grid systems. For Grid-tied systems, the inverter grounding is more complex and should be done by a qualified electrician.

Do you need a grounding electrode conductor for a solar inverter?

However, some contractors, who had been accustomed to grounding the system at the inverter, still prefer to install a grounding electrode conductor at that point. While this is permitted, per 690.47 (B), it is done only for grounding the PV equipment and not for grounding the PV system.

Do PV inverters need AC side grounding?

When a PV plant is installed in the distribution feeder, the plant shall meet the IEEE 1547 standard and the interface requirements of the local utility company. Some utility companies require PV inverters to have AC side grounding in order to assure compatibility with their grounding scheme, generally referred to as effective grounding.
