HEFEI, China – Speaking at the 2026 Global Renewable Energy Summit, Sungrow introduced its full-scenario commercial and industrial (C&I) energy storage ecosystem. The newly launched PowerKeeper series — a modular C&I ESS — is designed to achieve “0 waste” in investment and green power utilization, “0 outage” for C&I electricity consumption, and a streamlined experience across seven lifecycle upgrades (7Ups). According to the company, these features maximize long-term returns for business customers.

As an industry breakthrough, PowerKeeper is the first modular C&I ESS to successfully pass seven extreme challenge tests, a milestone that Sungrow says embodies its “007” value proposition — effectively redefining reliability standards in the C&I storage segment.

Seven extreme challenges: making safety invisible yet fundamental

Energy storage systems are built for a 20+ year service life, during which exposure to extreme weather, physical impacts, and unexpected incidents is nearly inevitable. True reliability, Sungrow argues, lies in proactively validating performance under the most punishing conditions. PowerKeeper inherits Sungrow's full-lifecycle safety system, undergoing over 700 pre-delivery tests per unit to guarantee durability and resilience. The seven extreme tests cover the entire lifecycle and a wide range of real-world scenarios, structured across three critical dimensions.
