BESSecure closes the sampling gap in conventional FAT

Advanced FAT that eliminates sampling-based risk, BESSecure puts every rack through rigorous analysis at the factory, before it leaves. Every defect that sampling would have missed is caught at source, not discovered in the field on a commissioned asset worth millions.

  • Discharge capacity and round-trip efficiency measured per rack to isolate underperforming units
  • Temperature-based indicators that flag early-stage degradation risk
  • Voltage deviation analysis to assess BMS performance and calibration accuracy

Evaluate 200-300 datapoints per container, including:

  • Discharging capacity & RTE per battery rack to identify bad apples
  • Temperature-related KPIs that anticipate accelerated degradation
  • Voltage-related deviations that assess BMS performance and calibration


Performing a BESS test, such as our BESSecure - BESS Quality Analysis, is therefore important and plays a crucial role in protecting your investment by enhancing the performance and safety of your assets. By identifying and replacing high-risk cells, modules and battery racks, we reduce the likelihood of failures, thus ensuring predictable performance and reliable grid interaction. This not only protects the physical asset but also secures your return on investment, making it a valuable tool for asset operators and asset owners alike. The reduced risk of fires and electrical shorts directly translates into lower maintenance costs, improved operational efficiency, and greater trust from your investors.



With BESSecure service, Sinovoltaics continues to be synonymous with innovation and the advancement of quality standards for battery energy storage systems (BESS).

BESSential White Paper

BESSential: Modernizing Traditional BESS Factory Acceptance Testing with Advanced Battery Diagnostics

As demand for Battery Energy Storage Systems (BESS) rises, deploying the most reliable BESS is essential for maintaining uptime and project revenue. Sinovoltaics and volytica diagnostics present BESSential—a new comprehensive QA solution that combines Factory and Site Acceptance Testing with advanced diagnostics. Read our white paper and learn how our BESSential FAT prevented over $600,000 in lost revenue and ensured early failure detection while improving the overall performance and reliability of a client’s 50 MWh BESS asset.

Inside the White Paper:

  • An in-depth case study demonstrating how BESSential’s testing can save you from major financial losses.
  • Insights on optimizing system performance for BESS projects.
  • The estimated industry cost for maintaining traditional FAT and SAT methods.
