NEC 706 Energy Storage Systems
NEC Article 706 covers Energy Storage Systems (ESS), including batteries used with solar PV systems, and details the requirements for labeling to identify stored energy and electrical hazards. Required labels communicate system presence, voltages, and disconnecting means.
The article requires permanent labels at ESS units, disconnects, and interconnection points with PV and utility sources. Please reference our ESS install type where labeling is broken out by battery unit, disconnect type and PSC controller.
