Provide an appropriate method of direct-to-earth grounding according to the latest edition of the National Electrical Code, including NEC 250: Grounding and Bonding, and NEC 690: Solar Photovoltaic Systems. Disconnect AC power before servicing or removing modules, AC modules, micro inverters and power optimizers.

1) Ground fault current always needs an effective return path back to the source. An equipment grounding conductor (EGC) provides such a path in most of the cases. In this regard, a main bonding jumper (MBJ) should be installed to connect the EGC to the neutral of the supply at one point only (see figure below).

Ground-fault protective devices (GFPDs) must meet four requirements; they must: 1) Detect ground-faults in the dc conductors of a PV system, including functionally grounded conductors; 2) Isolate faulted circuits from ground reference; 3) Indicate the occurrence of ground-faults; and 4) Be listed.

PV bracket and the foundation should be welded or mounted firmly between the bottom surface of the column and the concrete foundation contact surface with cement slurry to add irrigation, so that it is tightly combined. The bracket and PV module frame should be reliably connected to the protective grounding system.

6 FAQs about [The photovoltaic bracket should have a ground connection]

Do I need a grounding electrode for a PV array?

While a separate grounding electrode system is still permitted to be installed for a PV array, per 690.47 (B), it is no longer required to be bonded to the premises grounding electrode system. In PV systems with string inverters, the equipment grounding conductor from the array terminates to the inverter’s grounding bus bar.

What is the difference between grounded and ungrounded photovoltaic systems?

Grounded and ungrounded photovoltaic (PV) systems differ in design, implementation, and associated risks and benefits. Before comparing them, let’s explore each system in detail. What are Grounded Systems? These systems have a grounded conductor required by NEC Section 250-23 (b) to run to each service disconnecting means.

What is a solidly grounded PV array?

A solidly grounded PV array, as permitted, in 690.41 (B), as permitted, per 690.41 (A) (5), is a special case where the PV array contains no more than two source circuits, i.e., two strings of modules, the PV system circuitry is not located in or on a building, and the system is solidly grounded.

Can a solar PV practitioner read the NEC?

The summary outlined below can be used by a solar PV practitioner; however, it is highly recommended that section 690.41, 690.42, 690.43, 690.45 and 690.47 always be read in conjunction with section 240 of the NEC. Major points to remember: 1) Ground fault current always needs an effective return path back to the source.

What are the different types of ground mounted solar racking options?

Ground mounted solar racking options you can choose from are: Foundation mounts are the most common ground mounted structures. Their installation consists of preparing the land for excavation. Excavation is needed to put vertical pipes or mechanical tubing surrounded by a concrete foundation in place.

What if a PV array is not isolated from a grounded inverter?

A PV array that is not isolated from the grounded inverter output, as permitted, per 690.41 (A) (3), is where the grounded dc conductor from the PV array is directly coupled to the inverter’s grounded ac conductor.
