ENR-1022-ESS 1.02MWh liquid-cooled battery energy storage system

The ENR-1022-ESS is a high-capacity liquid-cooled lithium iron phosphate (LFP) battery energy storage enclosure designed for large-scale commercial and industrial energy storage, modular battery installations, and DC-coupled energy storage projects. With a nominal energy capacity of 1,022.72kWh, it combines high-capacity 1175Ah LFP cells, active liquid cooling, integrated battery management, and a high-voltage DC architecture in a compact enclosure.

High-Capacity LFP Battery System

Built around advanced 1175Ah LFP battery cells, the ENR-1022-ESS provides 1.02MWh of nominal energy capacity per enclosure. Its configuration consists of eight battery modules connected in series, each rated at 127.84kWh. The high-capacity cell design helps reduce the number of individual cells and electrical connection points required for a given energy capacity, simplifying system architecture and supporting streamlined integration.

Active Liquid Cooling and Thermal Management

The active liquid-cooling system helps regulate battery operating temperatures and supports stable operation across a wide ambient temperature range. The enclosure is specified for operation from -30°C to 55°C, with power derating above 45°C. This thermal management approach is suitable for demanding energy storage projects where temperature control, operational consistency, and battery lifecycle management are important.

High-Voltage DC Architecture

The system features a nominal DC voltage of 870.4V and an operating voltage range of 707.2–992.8V. This high-voltage architecture supports integration with compatible power conversion systems (PCS) and other DC-side equipment. Final system compatibility depends on the PCS voltage window, current limits, protection design, and project-specific electrical requirements.

Compact Footprint and Modular Expansion

With dimensions of 1,750 × 1,950 × 2,400mm, the ENR-1022-ESS occupies approximately 3.41m² of ground area per enclosure. Its compact form factor helps improve site utilization in large-scale battery installations. The modular architecture is designed to support DC-side multi-enclosure parallel expansion, subject to the selected PCS, battery controls, protection architecture, and system design.

Safety Monitoring and System Integration

The battery system incorporates a battery management system (BMS) with high-precision monitoring and passive balancing. Segmented physical barriers and integrated thermal isolation are intended to support battery safety management. CAN, RS485, and Ethernet communication interfaces facilitate integration with compatible supervisory controls, PCS equipment, and energy management systems.

The enclosure is specified with IP55 protection and corrosion-resistance options or ratings identified as C3H/C5M in the supplied technical information. Project-specific environmental suitability should be confirmed against the manufacturer’s test reports and the applicable installation conditions.

Lifecycle Cost Optimization

The use of high-capacity cells and pre-wired DC connections can help reduce installation complexity and on-site labor. The supplied product data specifies a cycle-life target exceeding 8,000 cycles, with remaining state of health (SOH) of at least 70%. Actual cycle life and levelized cost of storage (LCOS) depend on operating temperature, depth of discharge, charge/discharge rate, operating strategy, auxiliary consumption, and maintenance requirements.

Typical Applications

The ENR-1022-ESS is designed for integration into:

Commercial and industrial battery energy storage projects
Modular multi-enclosure battery storage installations
DC-coupled solar-plus-storage systems
Peak shaving and energy time-shifting projects
Renewable energy integration and large-scale battery storage systems

The ENR-1022-ESS provides a compact, high-capacity battery platform for energy storage system integrators seeking liquid-cooled LFP technology, high-voltage DC integration, and modular system expansion.

System configuration note: This product is a battery energy storage enclosure. PCS, EMS, transformers, grid connection equipment, and other balance-of-system components should be selected according to the project design unless explicitly included in the supply scope.
