FAQs 6

Why do battery energy storage systems need grounding and bonding?

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.

Can a battery circuit operate with ungrounded conductors?

When installing or inspecting storage systems of more than 100 volts, the battery circuits for an energy storage system that exceed 100 volts between the conductors or to ground is permitted to operate with ungrounded conductors.

Can you put a battery in a cabinet?

This document provides guidance for top clearance of valve-regulated lead-acid (VRLA) batteries, which are the most commonly used battery in cabinets. It is also made clear in 706.34 (C) that gas piping is not permitted in dedicated battery rooms. Mixture of a volatile gas in a corrosive location is a recipe for trouble.

How many volts can a dwelling unit energy storage system handle?

For dwelling units, an ESS cannot exceed 100 volts between conductors or to ground. An exception dictates that where live parts are not accessible during routine ESS maintenance, voltage exceeding 100 volts is permitted at the dwelling unit energy storage system. This information can be found at 706.30 (A).

Can batteries be used as energy storage systems?

Another important consideration when using batteries as an energy storage system is the guarding of live parts. Direction is given that guarding of live parts needs to comply with 110.27 titled “Grounding of Live Parts.” This includes protection against accidental contact or physical damage to the storage system.

Can a battery shelf contact a wall?

Energy storage system modules, battery cabinets, racks, or trays are permitted to contact adjacent walls or structures, provided that the battery shelf has a free air space for not less than 90 percent of its length.
