Project Brief

In the heart of the Swiss Alps, a premier marble processing facility has achieved energy independence by deploying a high-performance 400kWh DC-coupled Energy Storage System (ESS). This industrial-grade solution, featuring an integrated Power Conversion System (PCS), is designed to stabilize the facility’s heavy power demands, providing a sustainable and cost-effective energy framework for high-precision stone masonry.

Marble processing involves heavy machinery for cutting, grinding, and polishing, which creates significant peak demand charges and puts stress on the local grid.

• The Challenge: High electricity costs during peak production hours and the risk of voltage instability affecting sensitive CNC stone-cutting equipment.

• The Objective: To implement a robust peak-shaving strategy and integrate renewable energy for a lower carbon footprint in line with Swiss environmental regulations.

Project Highlights

• 400kWh High-Capacity Storage: Optimized for industrial duty cycles, the LiFePO4 battery array provides consistent, long-duration power to sustain heavy manufacturing processes.

• DC-Sided Efficiency: By utilizing a DC-coupled architecture, the system minimizes conversion losses between the solar array and the battery storage, ensuring maximum energy harvest and system efficiency.

• Advanced PCS Integration: The integrated Power Conversion System manages complex bi-directional energy flows, offering millisecond-level response times for Peak Shaving and Load Shifting.

• Grid Stability & Power Quality: The system acts as a buffer, filtering grid harmonics and protecting expensive marble-cutting machinery from voltage drops or surges.

• Swiss-Ready Reliability: Engineered for durability and high safety standards, the system features advanced thermal management suitable for year-round industrial environments.
