About BESS Manufacturers
BESS Manufacturers is a directory of battery energy storage system equipment manufacturers. We built it because procurement teams, developers, and engineers in the energy storage industry deserve a single, reliable place to compare suppliers.
What we do
We maintain detailed profiles for 76 manufacturers covering battery cells, DC blocks, PCS, AC blocks, and plant controls. Each profile includes technical specifications, product datasheets, certifications, financial data, and ESG reports — all sourced from public filings and official documentation.
We also publish in-depth analysis comparing manufacturers and tracking industry developments, and maintain a technical glossary for energy storage terminology.
The team
BESS Manufacturers is built and maintained by a small team of energy storage professionals based in Europe. We work in the BESS industry and created this directory to solve a problem we faced ourselves: fragmented, outdated, and hard-to-find manufacturer information.
Our editorial content is written by the team — manufacturer profiles are based on public filings and official documentation, not paid submissions.
Our principles
Facts only
Every data point comes from public filings, official datasheets, or company disclosures. We don't editorialize or rank manufacturers.
Free to use
The full directory is free to use. No login required, no gated content.
Built by industry professionals
We work in the BESS industry ourselves. The directory exists because we needed it — and so does the rest of the market.
