215kW 418kWh Battery Energy Storage System

215kW 418kWh Battery Energy Storage System (AIO ESS Cabinet)

Video

DC liquid-cooled battery energy storage systems are designed for commercial and industrial facilities such as industrial parks and data centers. They use a DC-coupled design to link photovoltaic generation, battery storage, and the power grid, which allows energy to move efficiently between production, storage, and consumption. These AIO ESS cabinets are rated at 215kW power output and 418kWh energy capacity and support daily load shifting by storing excess solar energy and releasing it during peak demand periods to improve self-consumption and reduce electricity costs.

Components

Battery Storage System:
LFP (lithium iron phosphate) battery cells are the core of our AIO energy storage systems, which provides a total capacity of 418kWh and supports up to 2 hours of full-load discharge. Their cell arrangement uses a 1P416S configuration, designed for up to 1500V DC operation, with overall efficiency reaching ≥94%.
Power Conversion System (PCS):
The integrated 215kW bi-directional inverter manages both grid-connected and off-grid operation. Four-quadrant control enables fast switching between charging and discharging, improving response to load variations.
Temperature Control System:
ESS cabinets use liquid cooling with Envicool units to maintain stable operating temperatures across the battery cells. Multi-level liquid cooling loop improves thermal control, supports easier maintenance access, and reduces the risk of leakage.
Safety Monitoring and Remote Control:
ESBMM, ESBCM, and ESMU provide control from cell level to full energy storage cabinet level, which keeps operation balanced and consistent across the entire battery system. The BMS and EMS inside the cabinet support Modbus RTU/TCP communication and cloud-based remote access for real-time monitoring and data management.
