Do I need a label for a solar PV system?

Solar PV labeling has been simplified for the 2017 code version. Here are the labels required by the NEC and/or NFPA 1 for the typical solar installation. NEC 690.13 (B) label is required at each PV system disconnecting means. This will include combiner boxes, AC/DC switches & AC Disconnects.

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.

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.

Are solar warning labels UV printed?

How do I know if my solar system is safe?

Voltage Rating Labels: Labels must indicate the nominal voltage of the solar installation. These should be placed at the main service disconnect, junction boxes, combiner boxes, and inverters. Warning Signs: Labels with warnings such as "DANGER: HIGH VOLTAGE" should be clearly visible at all points where electrical equipment is present.
