CSA C800-2025 — A New Standard for ESS Reliability and Quality Assurance

Manufacturers in the energy storage industry need to verify that their products address reliability, safety, and performance needs. To address a gap in existing energy storage systems (ESS) reliability assessments, CSA Group has introduced CSA C800-2025, a consensus standard designed to provide a rigorous testing protocol for energy storage systems reliability and quality assurance.

CSA C800-2025 goes beyond traditional safety and performance testing by incorporating large-scale fire testing and real-world extreme environmental stress conditions to assess durability and failure risks.

Why CSA C800-2025 Matters for ESS Manufacturers
