250kW Vestwoods PowerHelp Pro Series Energy Storage System

• Power Conversion & STS: 250 kW continuous (500 kW peak) bidirectional output; 3-phase 220/380 V (230/400 V) with built-in static transfer switching. Fast sub-10ms transfer ensures seamless backup or islanding operation. The integrated 275 kVA transformer provides galvanic isolation and compatibility with TN/IT/TT grid systems.
• Battery Modules: Scalable stack of 215 kWh LiFePO₄ cabinets (768 V nominal) – a standard 2-cabinet setup yields ~430 kWh (24×17.92 kWh cells). Additional cabinets can be added to expand storage. LiFePO₄ batteries offer very long life (~6000 cycles at 80% depth-of-discharge) with minimal capacity fade, enabling a design life of 10+ years.
• Safety & Thermal Control: Comprehensive protection with automatic fire suppression (aerosol or perfluoro options) and precision cooling. Onboard BMS/IMS continuously monitors cell voltage, current, and temperature, providing early fault detection. The enclosures meet IP55 (electronics) / IP54 (batteries) for dust/water resistance. The system also includes anti-islanding, surge protection, and redundant grounding to ensure high reliability.
• Smart EMS & Communications: Integrated Energy Management System (with intuitive 3D touchscreen HMI) enables configurable modes (peak shaving, time-of-use arbitrage, UPS, etc.) and monitors multi-unit parallel operation. Supports standard protocols (Modbus/RS485, CAN, Ethernet) for SCADA or building management integration. Bi-directional energy flow allows self-consumption of solar/wind generation, with up to 6 MPPT inputs (as per typical C&I inverter array) and grid-forming/grid-following flexibility.
• Additional Information: The system is designed to work with 110kW Deye string inverters, which are not included in the package and must be purchased separately. All battery cables are not included in the battery containers and must be sourced independently.
