GR261L — Industrial Battery
Energy Storage System The GR261L is a 261kWh all-in-one liquid-cooled battery storage system built for industrial and commercial applications. Using LFP chemistry with optional semi-solid batteries for 80% lower thermal risk, it offers plug-and-play deployment, AI-driven EMS, and multi-scene flexibility — from peak shaving to off-grid backup.
Description
The GR261L is Gooree's 261kWh all-in-one liquid-cooled battery energy storage system, built for industrial and commercial sites that need reliable, intelligent, and scalable energy storage. Based on proven LFP chemistry — with an optional semi-solid battery configuration that reduces thermal risk by up to 80% — the GR261L is engineered to handle the full range of commercial storage use cases: peak demand shaving, energy arbitrage, backup power, and self-consumption optimization from solar or other generation sources. Its plug-and-play all-in-one design cuts deployment time by up to 50% compared to component-based installations, and its AI-integrated EMS continuously optimizes charge and discharge strategy based on real-time grid and load conditions. Kuon offers the GR261L as part of its clean energy infrastructure portfolio, providing customers with a proven, certified system that can be deployed as a standalone unit or expanded through parallel configurations to meet larger site demands.
Technical Specifications
Battery & DC Side The GR261L uses LFP cells at 314Ah per cell, with an optional semi-solid chemistry upgrade available. The system configuration is 52S1P across five strings, giving a rated DC voltage of 832V and a DC voltage range of 702 to 949V. Battery capacity at beginning of life (BOL) is 261.24 kWh, with a charge/discharge rate capped at ≤0.5P to preserve long-term cell health. Thermal management is handled by a smart liquid cooling system for consistent performance across operating conditions.
AC Side Rated AC power is available in multiple configurations — 130kW, 125kW, 124.9kW, 100kW, or 99.9kW — selectable to match local grid connection agreements. The system connects to a 400V three-phase grid (3P+N+PE) at 50 or 60Hz, making it compatible with standard European commercial grid connections.
Performance & Longevity The GR261L is rated for a minimum of 6,000 full charge/discharge cycles at 25°C and 0.5P, maintaining a state of health (SOH) of ≥80% — equivalent to well over a decade of daily cycling under normal conditions. Overall system efficiency is ≥89%, inclusive of auxiliary and subsidiary power consumption.
Safety & Fire Suppression Multi-level fire protection is built in as standard, combining aerosol, NOVEC1230, or FM200 suppression agents at the pack level with flammable gas detection, active exhaust ventilation, and a water sprinkler system. The enclosure is rated IP55 and C4H anti-corrosion, suitable for outdoor industrial environments.
Monitoring & Communication The GR261L connects to Gooree's Cloud EMS platform and a dedicated mobile app for real-time monitoring, fault diagnosis, and remote control. Communication protocols include Modbus, IEC60870-5-104, and 4G via MQTT. The self-developed BMS and EMS support project-level customization and integrate AI algorithms for adaptive energy management.
Physical & Environmental The unit measures 1100 × 2519 × 1500mm (W×H×D) and weighs up to 2,500kg. It operates across an ambient temperature range of -30°C to +55°C (with integrated heater for operation down to -20°C without derating), and is rated for altitudes up to 4,000m with derating above 2,000m. Certifications include UN38.3, IEC62619, IEC62477, IEC61000, and EN50549.
