All-in-one 50kW/100kWh ESS cabinet for solar storage, backup, and peak shaving. 50kW and 125kW energy storage power modules, support on or off grid mode, air-cooled battery or liquid-cooled battery optional, has transformer, has STS module to achieve 10ms seamless switching. This series is specially designed to achieve PV & energy storage combination and backup power supply. What's included inside the integrated cabinet? The integrated cabinet includes LFP batteries, 50kW PCS, EMS, fire protection, AC/DC distribution, air cooling. The system uses cobalt-free LiFePO₄ (Lithium Iron Phosphate) battery technology, fundamentally eliminating the thermal runaway risks associated with cobalt-based lithium batteries. LiFePO₄ chemistry offers higher safety, longer lifespan, higher efficiency, and higher power density, supported by an. The Sunway 50kW/100kWh Outdoor Energy Storage System integrates high-performance lithium iron phosphate batteries, modular PCS, intelligent energy management, and a robust power distribution system—all within a weatherproof, front-maintenance cabinet. When the power generated by photovoltaic power generation iDesigned to support grid-tied and off-grid scenarios, the Hybrid ESS cabinet offers seamless integration and maximized space utilization, making it an ideal choice for growing energy demands. With support for 200% PV oversizing and a maximum 40A DC input current, the Hybrid ESS Cabinet ensures high.
