250kW-522kWh Outdoor Liquid-Cooled Lithium Battery Energy Storage System

Compact Utility-Scale Power for Commercial & Industrial Sites

The 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system is engineered for businesses that demand high power output and long-duration capacity in a single, weatherproof enclosure. By pairing a 250 kW power conversion system with 522 kWh of usable lithium-ion storage, the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system delivers four hours of continuous discharge at rated power, making the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system ideal for peak-shaving, tariff arbitrage and micro-grid support. Unlike conventional air-cooled cabinets, the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system uses a non-conductive dielectric fluid that circulates through every battery module, keeping cell temperature deviation below 2 °C across the entire 522 kWh pack. This thermal precision extends cycle life beyond 8 000 cycles and allows the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system to operate safely in ambient conditions from –30 °C to +55 °C without derating.

Integrated Safety & Cyber-Secure Architecture  

Every 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system ships with a multi-layer protection scheme: cell-level fuses, module-level flame-retardant vents, rack-level aerosol fire suppression and a stainless-steel liquid loop that isolates thermal events within seconds. A UL 9540A tested, IP54-rated enclosure shields the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system from driving rain, dust and corrosive salts, while an embedded IEC 62443-compliant PCS controller encrypts all outbound data, ensuring the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system meets stringent utility cyber-security mandates. Operators can monitor the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system through a local 15-inch HMI or a cloud dashboard that displays real-time SOC, SOH, voltage imbalance and coolant pressure, reducing O&M visits by up to 70 % compared with air-cooled alternatives.

Fast Plug-and-Play Deployment  

Installation of the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system is completed in four hours: a single forklift positions the 3 400 kg skid on a standard concrete pad, two AC cables land in the bottom-entry gland plate, and an RJ45 connection links the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system to existing EMS or SCADA networks. Because the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system contains pre-filled coolant, no on-site liquid handling is required. Once energized, the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system self-commissions, automatically detecting CT ratios, phase rotation and tariff schedules, so the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system can begin revenue-grade metering within minutes of arrival.

Scalable Micro-Grid Building Block  

Up to sixteen 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage systems can be paralleled on a 1 500 V DC bus for 4 MWh capacity without additional transformers or switchgear. A built-in droop-control algorithm allows each 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system to share load proportionally, eliminating circulating currents. When paired with rooftop PV or small wind, the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system provides island-mode black-start capability, re-energizing critical loads within 150 ms of grid loss. Optional DC-coupled EV chargers can draw up to 250 kW directly from the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system, turning parking lots into profit centers during peak-price windows.

Proven ROI & Warranty  

Under a typical California PG&E B-20 tariff, a single 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system can generate USD 62 000 in annual demand-charge savings plus another USD 18 000 from energy arbitrage, delivering a sub-five-year payback without incentives. The 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system is backed by a 10-year performance warranty that guarantees 80 % retained capacity at year 10, supported by a global service network that maintains local spare-part hubs on three continents. Remote firmware updates continuously optimize the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system control curves, ensuring the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system keeps pace with changing tariffs and grid codes for the full asset lifetime.
