6 FAQs about [Photovoltaic panel level marking specification requirements]
What are the labeling requirements for photovoltaic (PV) systems?
The National Electrical Code (NEC) Section 690 outlines specific labeling requirements for photovoltaic (PV) systems to ensure safety and compliance. These requirements were updated in 2020. Visibility After Installation: Labels or markings must remain visible after installation, ensuring they can be easily read during maintenance or emergencies.
Where should a warning label be applied to a photovoltaic system?
When the photovoltaic system also has batteries, the same warning shall also be applied by the installer in a visible location at the batteries. IBTS INTERPRETATION: A warning label shall be applied to the Inverter or near the ground fault indicator describing the hazard that would exist in the event of a ground fault.
How do you label a PV system?
The label shall be reflective, with all letters capitalized and having a minimum height of 3/8 in., in white on red background. A permanent readily visible label indicating the highest maximum dc voltage in a PV system, calculated in accordance with 690.7, shall be provided by the installer at one of the three locations.
Where should a photovoltaic circuit label be located?
Covers or enclosures of pull boxes and junction boxes Conduit bodies in which any of the available conduit openings are unused The labels or markings shall be visible after installation. Photovoltaic power circuit labels shall appear on every section of the wiring system that is separated by enclosures, walls, partitions, ceilings or oors.
How do I know if a PV system has a high DC voltage?
A permanent readily visible label indicating the highest maximum dc voltage in a PV system, calculated in accordance with 690.7, shall be provided by the installer at one of the three locations. Buildings with More Than One Rapid Shutdown Type.
Why is safety labeling important for solar installation?
Proper safety labeling is a critical aspect of solar installation safety, helping to prevent accidents and injuries by clearly communicating potential hazards. By adhering to established standards such as ANSI Z535, NFPA 70E, OSHA’s HCS, and NEC 690, solar installers and operators can ensure their systems are safe for everyone involved.
