BESS for Construction Power Solutions
Complete Sustainable, Reliable Low-Carbon Power Solution for Construction Sites
Power is the lifeline of every construction site. While diesel generators have long been the go-to option for temporary power, their high fuel costs, noise, and carbon emissions are no longer sustainable.
Our Energy Storage Power Amplification Cabinet is a purpose-built construction battery solution and a mobile BESS for construction sites. It provides zero-emission, low-noise, and high-reliability power — reducing operational costs while enabling contractors to meet green building and ESG goals.
Key Features
- High Output: Up to 500 kW output to power cranes, piling rigs, and concrete plants
- Flexible Integration: Works with both grid and diesel generators, seamless on/off-grid switching
- Green & Low-Carbon: Zero emissions, low noise, fully compliant with sustainable construction standards
- Safety First: IP55 protection, full electrical safeguards, FK-5-1-12 fire suppression system
- Smart Operation: Remote monitoring, proactive alerts, preventive maintenance
- Global Compliance: Certified with UL1973, UL9540A, IEC62619 for worldwide use
How It Works & Applications
- Construction Sites: Tower cranes, piling machines, batching plants, site offices & camps
- Diesel Generator Replacement: Reduce diesel runtime by over 50%
- Mobile BESS Deployment: Plug-and-play, fast installation, ideal for temporary power
