FAQ

What are the core specifications of the 125kW + 241kWh BESS outdoor cabinet?

This BESS outdoor cabinet is an integrated outdoor energy storage system, integrating a 125kW high-efficiency PCS (Power Conversion System), 241kWh lithium iron phosphate (LiFePO₄) battery pack, intelligent BMS (Battery Management System), and outdoor protection components in one integrated enclosure. Its nominal continuous discharge power is 125kW, rated energy is 241kWh, and it adopts a high-voltage DC design (300V-800V) to match large-scale commercial and industrial power demand. It is specially designed for outdoor use with enhanced protection level, supporting grid-connected, off-grid, peak-shaving/valley-filling, and renewable energy supporting modes.

What battery chemistry is used in the 241kWh energy storage part, and what safety guarantees does it provide for outdoor industrial scenarios?

The 241kWh energy storage module adopts high-quality lithium iron phosphate (LiFePO₄) battery cells, which are the preferred choice for outdoor BESS due to their excellent safety, high temperature resistance, and low temperature adaptability. It has passed strict international safety certifications (IEC 62619, UL 9540, GB/T 36276), with no risk of thermal runaway, fire, or explosion even under extreme outdoor conditions (high temperature, heavy rain, frost, or impact). The outdoor cabinet is also equipped with a professional fire suppression system, smoke/temperature detection, and waterproof and dustproof structures to fully adapt to harsh outdoor working environments.

What are the core application scenarios of this 125kW + 241kWh BESS outdoor cabinet?

It is mainly used in outdoor commercial and industrial energy storage scenarios, including: large factories and industrial parks (peak-shaving and valley-filling to reduce electricity costs, ensuring uninterrupted power supply for production lines); outdoor renewable energy supporting (matching large-scale rooftop solar, ground-mounted solar, or small wind power systems to store surplus power and stabilize grid connection); commercial plazas and outdoor markets (backup power for lighting, air conditioning, and business equipment during grid outages); remote industrial sites (mines, construction sites, rural industrial parks) off-grid power supply; and grid auxiliary services (frequency regulation, peak load shifting) for power grid companies.
