Surge Protection for Energy Storage Systems (ESS)

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 associated components like Inverters, Power Conversion Modules, Power Panels, Battery Chargers, Solar Tracking Modules, Sensors and other alternative energy sources.
