500kW Vestwoods PowerHelp Pro Series Energy Storage System

• Power Conversion & Transformer: 500 kW continuous (3-phase 220/380 V) output, 550 kVA dry transformer. The built-in STS and transformer enable robust parallel operation (grid-forming or grid-following) and meet strict harmonic and safety regulations. Rated AC current is ~720 A (380 V), allowing connection to large loads or paralleling with generators.
• Battery Capacity: Five 215 kWh LiFePO₄ cabinets provide ~1075 kWh of storage (60×17.92 kWh cells). Modular stacking means capacity can be scaled by adding more cabinets – up to 10 (each with its own cooling and monitoring). These high-voltage battery modules deliver long service life – over 6000 cycles at 80% DoD.
• Environmental Controls: Tiered safety includes integrated fire suppression (sprinkler or gaseous), compartmentalized thermal management, and multi-layer battery isolation. The system is designed for full life performance in –30 °C to +60 °C ambient, with IP55 ingress protection (electronics) and IP54 for battery racks. All enclosures are weatherproof and EMC-compliant. Hardware interlocks and leak detection enhance safety in demanding installations.
• Intelligent Management & Integration: Onboard EMS/EMS software (with HMI or remote interface) supports advanced functions like multi-unit parallel operation, black start, and smooth off-grid transition. The 500kW system can coordinate with multiple PV inverters and generators – energy flows bidirectionally for grid support (frequency regulation, peak shaving) or self-consumption. It interfaces via standard protocols (Modbus/RS485, Ethernet, etc.) for plant-wide energy management.
• Additional Information: The system is designed to work with 110kW Deye string inverters, which are not included in the package and need to be purchased separately. Additionally, all battery cables are not included in the battery containers and must be sourced independently.
