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.
These low resistance levels allow fault currents to easily discharge into the ground, protecting people, equipment and the BESS itself. The consequences of a failed or insufficient grounding system can be severe – thermal runaway leading to fires, system downtime, component failures, reduced efficiency and other safety hazards.
A recent six-year audit by Clean Energy Associates found that over 25% of grid battery systems had manufacturing defects, putting them at high risk in these areas. The most common causes of defects were quality control issues from the assembly and installation of integrated systems, such as the grounding and bonding components.
A reliable suite of grounding products is essential to a turnkey grounding system, including ground rods, grounding connections (compression, mechanical, exothermic), theft-deterrent grounding conductors, ground enhancement material, and cutting and crimping tools.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
