Surge Protection for Energy Storage Systems (ESS)

Energy Storage Systems1

OVERVIEW

Today's increased reliance on very sensitive electronics makes surge protection an important topic for Energy Storage Systems or ESS. 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 Energy Storage System and all the associates components like Inverters, Power Conversion Modules, Power Panels, Battery Chargers, Solar Tracking Modules, Sensors and other alternative energy sources.

Selecting SPD for Energy Storage System (ESS)

NEC/NFPA 70 require that Surge Protective Devices (SPDs) shall be UL1449 Listed. This means selecting a surge protector is easier than it has ever been. There are only a few choices available for SPDs that are UL Listed for any of the most commonly used surge standards including UL1449 5th Edition, UL497B, and UL497E.
