6 FAQs about [Photovoltaic array grounding terminal board]
Does a PV array need a grounding conductor?
Since the PV array and other electrical equipment in PV system, e.g., inverters, are often located remotely from one another, 690.43 (B) requires that an equipment grounding conductor (EGC) be run from the array to other associated equipment.
Do ungrounded PV arrays need a grounding terminal?
There is no requirement directly addressing the ungrounded PV array connected to a utility-interactive inverter as allowed by 690.35. Most ungrounded PV arrays will be connected to utility-interactive inverters and those inverters have common ac and dc equipment grounding terminals.
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 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.
Why is proper grounding of a photovoltaic power system important?
Proper grounding of a photovoltaic (PV) power system is critical to ensuring the safety of the public during the installation’s decades-long life. Although all components of a PV system may not be fully functional for this period of time, the basic PV module can produce potentially dangerous currents and voltages for the life of the system.
Does grounding a PV array make a system less susceptible to lightning?
The First Revision of the 2017 NEC places this requirement in positive language, rather than as an exception. The informational note in 690.42 states that grounding a PV array close to the PV array makes the system less susceptible to lightning. This note is not always true and has been eliminated from the 2017 First Revision language.
