A new solar-powered battery system may offer construction and infrastructure sites a practical alternative to traditional diesel generators. Designed for high-demand and off-grid applications, the ProCharge Battery Energy Storage System (BESS) delivers 120 kWh of energy storage and aims to support the growing push toward cleaner, quieter, and more efficient operations.
The system integrates a lithium-ion battery pack with 12 solar panels and a three-phase power output of up to 45 kVA. Developed for large site compounds, ProCharge can operate as a standalone energy source or in a hybrid configuration with HVO or diesel generators. This allows construction teams to reduce generator use significantly while maintaining energy reliability.
According to Interesting Engineering, unlike many conventional systems, ProCharge is built with full off-grid functionality. Its integrated solar array enables self-charging during the day, minimizing fuel consumption and emissions. It is particularly well-suited to projects aiming to reduce their carbon footprint, especially in remote or environmentally sensitive areas.
In early trials, a prototype version of the system was deployed on the A417 Missing Link Project in the UK. Even with a smaller 8-panel configuration, the system demonstrated considerable fuel and emissions savings. The upgraded version now includes 12 panels, enhancing power output and efficiency.
One of the system’s key features is its quiet operation, making it suitable for use in noise-sensitive environments such as residential areas or during night shifts. Additionally, its energy output can support a range of electric machinery—such as telehandlers, mini diggers, small EVs, and all-terrain vehicles—enabling more widespread adoption of zero-emission equipment on site.
The unit is mounted on a skid for easy transport and is compatible with standard UK 3-phase distribution boards. Remote monitoring and data insights are accessible via a built-in telematics system, offering real-time oversight of performance and usage.
By reducing the daily runtime of diesel generators and supplementing them only when necessary, the system offers a hybrid energy model that aligns with the construction industry’s shift toward lower emissions and greater energy efficiency.
