6 FAQs about [Photovoltaic inverter safety marking drawing]

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.

Do PV systems need labels and warning signs?

Installers should consult the National Electricians Code (NEC) regarding PV systems and any local regulations from cities and municipalities. The basic parts of a PV system that need labels and warning signs include the following: Now that we know what needs labeling, we’ll explore the PV labeling requirements that installers need to know.

Do I need a warning label on my PV inverter?

Section 690.5 covers the ground fault detection/interruption for the PV system and requires a warning label on the utility-interactive inverter or near the ground-fault indicator at a visible location. Most often, these labels are applied on the inverter by the manufacturer. See Figure 1. Figure 2.

Why are labeling requirements important for PV systems?

Before we get into the labeling requirements for PV systems, it’s worth noting why these labels are important for installers and owners of PV systems. There’s always the danger of short circuits, arc flashes, and fires to installers and anyone nearby if they’re not careful.

Where can I find a label for a PV inverter?

Section 690.54 requires a label at the point where the PV system interconnects to other sources such as the premises wiring system. The label must have the rated ac output current and the nominal operating ac voltage. This rated ac output current can be found on the inverter nameplate. See Figure 6.

How do I know if my solar installation is safe?

Proper labeling is crucial to warn personnel of these dangers. Key requirements include: 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.
