IF YOU COULD INSPECT IT ALL, IN THE SNAP OF A FINGER, WHY WOULDN’T YOU?

At Sinovoltaics, our work is not done until 100% of your equipment is held to the highest standards. BESSential is our flagship innovation offering 100% battery module review. With our software, thermal, electrical, and capacity disbalance is detected and corrected during your Factory Acceptance Testing (FAT) test.

During the factory acceptance testing on the manufacturer floor, extensive electrical and performance tests are conducted on the battery energy storage container. A vast amount of data is collected during these tests, which is then fed into our BESSential software for detailed analysis. We evaluate each and every module and can push our analysis to the cell level. In evaluating each battery pack, we identify volatility in individual cells, such as temperature shifts, voltage irregularities, capacity disbalance, and other factors predictive of earlier sign of battery pack/cells defects.



Performing a BESS test, such as our BESSential - 100% Battery Pack review, 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 BESSential service, Sinovoltaics continues to be synonymous with innovation and the advancement of quality standards for battery energy storage systems (BESS).
