500kW 1MWh Container Battery Storage System
These container battery storage systems are designed for commercial and industrial peak shaving, solar energy storage, and microgrid applications. They are usually designed in a 20-foot container that combines 1.045MWh of LFP battery capacity with a 500kW power conversion system (PCS), which allows the batteries to work with solar power, the utility grid, and other energy sources while switching smoothly between grid-connected and off-grid operation. They use liquid cooling to maintain cell temperature differences within 3°C and support operation from -30°C to 50°C. Our ESS containers are equipped with five-in-one safety detection, aerosol fire suppression, and IP54 protection. They are structurally engineered to comply with Eurocode 8 (EN 1998-1-1:2024) standards, ensuring exceptional seismic resistance for reliable outdoor operation in diverse environments.
-
Integrated Container Design
- Batteries, power conversion system (PCS), cooling, fire protection, and control systems are installed inside the 20-foot containers before delivery.
- We carry out factory testing before delivery to reduce on-site wiring and make installation and commissioning faster and easier.
-
Flexible Multi-Energy Operation
- ESS containers can coordinate power from solar PV, wind turbines, diesel generators, and the utility grid.
- Automatic PQ/VF switching supports grid-connected, off-grid, and backup operation without disrupting power supply.
-
Efficient Liquid Cooling
- The energy storage systems use liquid cooling to keep cell temperature differences within 3°C and can improve battery cycle life by 20%.
- Thanks to their smart temperature control auxiliary power use is reduced by 30%, while single-cycle AC-side efficiency reaches at least 94%.
-
Multi-Level Safety Protection
- Five-in-one detection, smoke and heat sensors, and aerosol fire suppression provide three levels of fire protection.
- IP54 enclosure protection, C4 corrosion resistance, and seismic resistance up to intensity level 7 support reliable operation in demanding environments.
-
Multi-Energy Coordination
Supports automatic control of solar PV, wind power, and diesel generators, including generator start and stop
-
Flexible Operating Modes
Switches automatically between PQ and VF control for grid-connected, off-grid, and hybrid operation
-
Intelligent Temperature Control
Automatically switches between PQ control for grid-connected operation and VF control for off-grid power supply, while also supporting hybrid operation
-
Fire Protection
Five-in-one detection, aerosol fire suppression, audible and visual alarms, and remote emergency shutdown provide layered protection
-
Communication and Cloud Access
Modbus TCP, CAN, and RS-485 interfaces support connection to cloud platforms and energy management system
-
Remote Maintenance Support
Remote monitoring, fault alerts, data analysis, and over-the-air (OTA) updates simplify system maintenance

- Battery System:
These containerized energy storage systems use 3.2V/314Ah LFP cells arranged in five 1P208S battery strings. They operate at 665.6V, supports charging and discharging up to 0.5C, and are designed for a service life of up to 20 years.
- Power Conversion System (PCS):
The integrated 500kW bidirectional PCS manages charging and discharging with system efficiency of at least 94%. It automatically switches between PQ control for grid-connected operation and VF control for off-grid supply, while also coordinating solar PV, wind power, and diesel generators.
- Temperature Control System:
Liquid cooling keeps cell temperature differences within 3°C, which helps extend battery cycle life by 20%. Intelligent temperature control also reduces auxiliary power use by 30% and supports operation from -30°C to 50°C.
- Intelligent Monitoring and Remote Control:
Five-in-one detection, aerosol fire suppression, audible and visual alarms, and remote emergency shutdown help protect the battery containers during operation. Modbus TCP, CAN, and RS-485 connections also allow remote monitoring and control through cloud platforms and energy management systems.
- Community Microgrids
Used as the main storage and control unit for local energy distribution and coordinated grid services
- EV Fast Charging Hubs
Suitable for sites that combine 280kW fast charging with 1MWh battery storage to reduce grid demand, prevent transformer overload, and support integrated solar, storage, and charging operation
- Grid Support Services
Ideal for primary control reserve (PCR), peak shaving, and other grid service programs that can generate additional revenue from available battery capacity
