105kW/215kWh All-in-One Energy Storage System

105kW 215kWh All-in-One Battery Storage System

All-in-One Liquid-Cooled Energy Storage System with Built-in PCS and Intelligent Temperature Control

All-in-one energy storage systems (105kW/215kWh) are designed with high energy density lithium iron phosphate batteries and liquid cooling technology. They integrate energy management, intelligent dispatch, and safety protection within a single energy storage cabinet, providing stable and cost-efficient storage solutions for industrial and commercial applications.

Our AIO energy storage systems combine a 105kW bi-directional PCS with 215kWh battery capacity to manage energy flow between charging and discharging. They support multiple operating modes such as peak shaving, demand charge management, solar self-consumption, and backup power supply. These 105kW/215kWh all-in-one ESS use liquid cooling technology to keep battery temperatures stable throughout the full lifecycle, improving cell consistency, extending service life, and maintaining safe operation under continuous high-load conditions.

Features

Integrated Design with Smaller Footprint
1. The battery, power conversion system (PCS), thermal management, and fire protection are integrated into a single ESS cabinet designed for outdoor installation, that reduces the need for additional construction work.
2. They have a compact structure that saves space during installation and it’s easier to deploy in sites with limited conditions.
Liquid Cooling for Stable Performance
1. Liquid cooling technology keeps battery cells within a tight temperature range (≤3°C difference), which helps maintain stable operation and improves long-term reliability.
2. The wide operating range from -20°C to 55°C allows these ESS cabinets to work reliably in both hot and cold environments.
Modular Design for Flexible Expansion
1. Our AIO ESS cabinets architecture supports connection of multiple energy storage units, which allows capacity to scale up to MWh-level systems with flexible expansion.
2. On-site installation and commissioning take only 3–5 days and enable fast commissioning while shortening the project timeline.
High-Efficiency Energy Management
1. AIO ESS cabinets’ efficiency reaches ≥88% under test conditions and enables four-quadrant operation for smooth switching between charging and discharging.
2. Their integrated power conversion system (PCS) supports coordination with solar, diesel generators, and other energy sources in hybrid applications.
Multi-Level Safety Protection
1. Lithium iron phosphate batteries support more than 6000 cycles (90% DoD, 25°C), ensuring stable long-term operation with reduced degradation.
2. An aerosol-based fire suppression system, combined with IP54/IP65 protection and IEC 62619 compliance, enhances overall operational safety.
Smart O&M and Remote Monitoring
1. Modbus and RS-485 communication connect the AIO energy storage system with external energy management platforms.
2. Mobile and PC monitoring provides real-time access to operating status, energy data, and fault alerts, thanks to which maintenance costs are reduced by more than 30%.

Components

Battery Storage System:
Lithium iron phosphate (LFP) batteries provide 215kWh rated capacity with a cycle life of over 6000 cycles (90% DoD, 25°C). The battery pack supports wide-temperature operation, with a charging range of 0–55°C and a discharging range of -20–55°C for stable performance in different environments.
Power Conversion System (PCS):
The 105kW bi-directional converter manages AC and DC power flow with system efficiency ≥88% under tested conditions. It supports four-quadrant operation for smooth switching between charging and discharging and enables coordination with solar PV and diesel generator systems in both grid-connected and off-grid modes.
Temperature Control System:
Liquid cooling combined with forced air cooling keeps battery temperature difference within 3°C, improving cycle life and system stability while supporting reliable operation across a wide temperature range from -20°C to 55°C under different climate conditions.
Safety Monitoring and Remote Control:
BMS and EMS manage system monitoring, energy control, and communication through Modbus/RS-485. Integration with energy management platforms supports real-time monitoring of operating status, battery data, and fault alarms across mobile and PC interfaces, while reducing O&M costs by over 30%.
