Sunwoda Oasis L261 All-in-One Cabinet - No STS
The Sunwoda OASIS L261 is a liquid-cooled, all-in-one LFP battery energy storage cabinet for commercial and industrial projects. With 261 kWh rated energy capacity and 125 kW rated AC output power, it supports solar self-consumption, peak shaving, load shifting and wider C&I energy management applications.
Built with Sunwoda’s 314 Ah LFP cells, the cabinet integrates the battery packs, BMS, PCS, liquid cooling, monitoring and fire-protection systems within one outdoor-ready enclosure. Its modular design supports parallel expansion, subject to final system design and site requirements.
Sunwoda Energy is a BloombergNEF Tier 1 Energy Storage Manufacturer with in-house battery-cell production and decades of lithium-ion battery experience.
 This version does not include an integrated Static Transfer Switch (STS) module. If backup operation with grid/off-grid switching is required, the optional STS module must be specified separately according to the final system design.
