6 FAQs about [General description of photovoltaic panel grounding electrode]
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.
Does a photovoltaic system have a DC grounding system?
Photovoltaic systems having dc circuits and ac circuits with no direct connection between the dc grounded conductor and ac grounded conductor shall have a dc grounding system. The dc grounding system shall be bonded to the ac grounding system by one of the methods in (1), (2), or (3).
Do all electrical systems need a grounding electrode system?
A quick review of the grounding electrode system requirements of Article 250 show that all electrical systems require a grounding electrode system. The size of the electrode system is a function of the size of the service conductors [250.66].
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.
What are equipment grounding requirements for PV systems?
Equipment grounding requirements for PV systems are covered in 690.43. These requirements include the bonding and grounding requirements for exposed metal parts of PV systems such as metallic module frames, electrical equipment, and conductor enclosures [690.43 (A)].
Where should a grounded PV system conductor be grounded?
The location where grounded PV system conductors must be grounded is covered in 690.42. It states that a grounded PV array must be grounded at the ground-fault protection device—and at no other location.
