Proper Grounding is Critical for Battery Energy Storage Systems
For grid-scale battery energy storage systems (BESS), grounding and bonding is essential for safety and performance. The goal of grounding and bonding is to achieve customer-targeted resistance levels. These low resistance levels allow fault currents to easily discharge into the ground, protecting people, equipment and the BESS itself.

System Neutral Grounding Considerations for Inverter-Interfaced
Distributed energy resources, DER generation and electrical storage, are commonly interfaced to the grid using power electronic inverters. Inverter interfaced sources differ fundamentally from synchronous generators. Synchronous generators are well represented in power system analysis by a constant ac voltage source in series with a reactance.
Energy storage systems–NEC Article 706 – IAEI Magazine
The scope of Article 706 informs Code users that this information applies to all permanently installed energy storage systems. This applies to ESSs operating at more than 50 volts AC or 60 volts DC. These may be stand-alone or interactive with other electric power production sources. Photo 1.
