Model:ST255CS-2H, battery capacity 257kWh, rated AC power 125kW

Product Features

Safe and reliable

1. AI-based cell health pre-diagnosis gives early warning of cell anomalies, avoiding thermal runaway risks

2. Three-level overcurrent protection at pack, cluster and PCS level with precise short-circuit current analysis, reducing losses

3. IP55 enclosure protection and IP66 for the PCS, C5 anti-corrosion supported, adaptable to harsh outdoor environments

4. Millisecond-level response to grid fluctuations; supports off-grid operation of critical loads and grid inertia compensation for a more stable power supply

Intelligent and efficient

1. AI bionic thermal balance reduces cooling losses by 33%; overall system efficiency of 88% or higher

2. PCS maximum efficiency 98.5%, three-phase four-wire direct output, adapting to various power consumption scenarios

3. EMS intelligent algorithm model automatically generates energy dispatch strategies to improve project returns

Worry-free and convenient

1. Pre-installed and pre-commissioned at the factory, plug-and-play for fast grid connection and simple deployment

2. Operating noise of 65dB or less, environmentally friendly; supports cloud OTA remote upgrade for fast fault response

3. Visualized O&M management with centralized multi-site monitoring, real-time view of device status and returns
