What are the PV system marking and labeling requirements?

Here is a quick summary of PV system marking and labeling requirements. 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.

How do I install a solar photovoltaic system?

Installing solar photovoltaic systems requires specialized skills and knowledge. Installation should only be performed by qualified personnel. Before installing a solar photovoltaic system, installers should familiarize themselves with its mechanical and electrical requirements.

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.

What is a severe rating on a solar PV module?

The schematics in the Terminology section describe where each component is found on a common solar PV module. A Severity Rating is also defined to give users guidelines on how concerning a particular defect may be.

Is a Trina Solar PV module ul1703 compliant?

The fire rating of a Trina Solar PV module is valid only when mounted in the manner specified in the mechanical mounting instructions of this installation manual. The module is considered to be in compliance with UL1703 only when the module is mounted in the manner specified by the mounting instructions below.

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.
