Surge Protection for Photovoltaic Lighting

Photovoltaic-Solar-Multiple
Photovoltaic Lighting

OVERVIEW

Today's increased reliance on very sensitive electronics makes surge protection an important topic for Photovoltaic Lighting, LED Street Lights and Smart Lighting Poles. The Insurance Institute for Business & Home Safety study found that $26 billion dollars was lost due to non-lightning power surges. In addition, there are about 25 million lightning strikes in the US each year that cause between $650M to $1B in losses according to the Insurance Information Institute, State Farm©. This page discusses how to best protect your Photovoltaic powered lighting system, LED Luminaire, Wireless Transmitters, IoT devices and other smart electronics with a Surge Protective Device (SPD) or multiple SPD’s.

Selecting the appropriate SPD

UL8801 requires surge suppression, whether individual or in combination with some other component(s), shall comply with the requirements of the applicable UL standard(s) that cover devices that provide those functions. This means selecting a surge protector from the following UL standards including UL1449 5th Edition, UL497B, and UL497E.
