4 FAQs about Equipment grounding inside the energy storage cabinet

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.

Why is EMC grounding important?

Grounding is an essential part of cabinet assembly. ensures that installation is safe. That means protection and safety design according to short circuit capability. and improves immunity against electromagnetic interference. Note: EMC grounding reduces reactance for high frequency currents!

Should a cabinet be grounded if it is not painted?

If the cabinet is not painted, zinc coating treatment inside ensures that all mechanical joints conduct properly. If the cabinet is painted, all components and installation plates should be grounded via a cable to the grounding busbar. Body grounding does not replace a protective earth connection.

How long does a grounding system last?

High-quality, value-engineered grounding systems are key to meeting the desired BESS infrastructure service life of at least 25 years. Other solutions may meet these requirements initially but will degrade over time. nVent provides tested solutions that will deliver long-term consistent results.
