Warning: PV String Disconnection Point #___

This label marks a numbered PV String Disconnection Point, giving each individual string on a solar array its own distinct isolation marker rather than a single catch-all warning sign. The number field lets installers and maintenance crews match a specific physical disconnect to its documented string during commissioning, testing or fault-finding, cutting out guesswork on site. It's built for arrays with multiple string disconnects requiring individual identification, such as larger commercial installations where combiner boxes or array enclosures house several isolation points side by side.

Made from yellow Traffolyte measuring 145mm x 25mm, the wording is laser engraved rather than printed, so the number and warning text stay legible rather than wearing away over time. The yellow face gives clear visual contrast for a warning marking, and the larger format suits switchboards and combiner boxes where a numbered string identifier needs to stand out clearly among other panel labelling.
