Pylontech launches PyOcean 6.4 MWh energy storage system at Intersolar Europe

Pylontech unveiled PyOcean, a new utility-scale battery energy storage platform, at Intersolar Europe in Munich on June 26, 2026. The platform includes a 6.4 MWh system using Pylontech’s in-house 601 Ah LFP cells and a 6.26 MWh version equipped with 588 Ah cells, which the company said demonstrates its vertically integrated capabilities from battery cell development to system integration. The 6.4 MWh, 0.25P system is aimed at renewable co-location, energy shifting, capacity-value projects and evening or night peak delivery, while the 6.26 MWh, 0.5P system is designed for standalone BESS, grid-side flexibility, peak shaving and other high-frequency cycling applications. Pylontech said the 601 Ah cells reach energy density of up to 426 Wh/L, allowing more energy capacity within a standard 20-foot container while reducing land use, infrastructure needs and project costs. The company also said PyOcean features factory pre-assembly, multilayer safety protection and intelligent operation through a local energy management system. Pylontech cited a 400 MWh project in Ningxia and an 80 MWh project in Jiangsu over the past year, along with its inclusion on BloombergNEF’s Tier 1 energy storage system manufacturer list, as it expands further into large-scale storage.
