In summary, you should be allowed to install an inverter with an integrated disconnect at a higher level if you provide an additional safety switch that is less than 6'-7" above the floor. A switch cannot be more than two meters (6-7") from the floor. Code is 404.8.How a solar inverter is connected to a PV system?The inverter is connected to the single ground rod used for both AC and DC using the GEC. While the PV array and inverter is connected to the main grounding terminal in the main panel through he EGC. In this grounding method, a single copper ground rod is used for both AC system and DC solar panel system using combined DC GEC and AC EGC.
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 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.
Do inverters have a grounding point?Some modern inverters are fitted with a grounding point connection in the inverter circuitry. Still, this grounding point must be disconnected when the inverter is connected to a power distribution panel with its grounding. The inverter must not be double grounded as this may cause a problem.
Which grounding rods are used in a solar inverter?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.
Do solar inverters need a ground wire?The AC output terminals of the inverter supply the Neutral to Ground connection, and no secondary grounding connections are permitted.
