Swedish Industrial Park Enhances Energy Resilience with Advanced Power Conversion System Deployment

Strategic procurement of scalable PCS solution supports hybrid solar-storage project in Nordic climate

STOCKHOLM, SWEDEN – March 2024 – In a decisive move to bolster energy security and integrate renewable sources, a major industrial park operator in Västerås, Sweden, has successfully commissioned a state-of-the-art Power Conversion System (PCS). The project, led by veteran energy solutions manager Lars Johansson, aimed to create a robust, flexible link between a newly installed solar array, a large-scale battery energy storage system (BESS), and the facility's critical manufacturing load.

Faced with grid capacity constraints and a commitment to reduce carbon footprint, the project team initiated a detailed international tender in Q4 2023. The key requirements were clear: high efficiency, proven reliability in cold climates, seamless transition between on-grid and off-grid operation, and compliance with stringent European standards.

"Our operational reality demands uninterrupted power for precision manufacturing," explained Johansson. "We needed a PCS that wasn't just an inverter, but the intelligent heart of a microgrid. It had to manage diverse inputs—from our PV panels and lithium-ion batteries—and output perfectly synchronized, clean power to our machinery, regardless of grid conditions."

After a rigorous evaluation process, the procurement team selected a high-power, three-phase PCS solution matching the specifications of the Monet-1000 model from the considered product series. This selection was driven by its impressive 1000kW rated AC power, a wide operating voltage range compatible with modern battery strings, and its explicit certification for key European (EN) and International (IEC) standards.

The Procured Power Conversion System & Complete Suite of Components:

The purchased system represents a fully integrated solution. The core hardware and ancillary components supplied include:

1. Main PCS Unit: The primary conversion cabinet, housing power electronics, cooling systems, and control boards.

2. DC Disconnect Switches & Fuses: Isolators and over-current protection for both the photovoltaic input and battery DC links.

3. AC Circuit Breakers: Protection devices for the connection to the facility's 400V AC distribution board.

4. Communication & Monitoring Hub: Includes modules for RS485, CAN, and Ethernet interfaces, enabling integration with the site's energy management system (EMS) and remote monitoring platforms.

5. Step-up Transformer (if applicable): For grid interconnection at a required voltage level.

6. Low-Voltage Auxiliary Power Supply: Powers the internal controls and cooling fans.

7. Harmonic Filtering Components: Ensures output Total Harmonic Distortion (THDi) remains below 3% for linear loads, protecting sensitive equipment.

8. Environmental Sensors: Monitors ambient conditions within the enclosure.

9. Mounting Kit & Cable Management System: Includes rails, brackets, and cable trays for secure installation in the designated utility room.

10. Detailed Documentation Pack: Installation manuals, wiring diagrams, commissioning guides, and full certification dossiers for EN 61000-6 series, IEC 62477-1, and IEC 62116.

The system's specifications were particularly appealing for the Swedish context. Its operational ambient temperature range of -25°C to +60°C guarantees performance through harsh Scandinavian winters. The intelligent air-cooled design ensures efficiency without liquid coolant complexities, while the altitude rating accommodates various European locales.

Commissioning was completed in early March 2024. The PCS now dynamically manages energy flow, performing peak shaving, providing backup power during grid outages with its off-grid capability, and exporting surplus solar energy. The PF adjustable range allows the facility to provide reactive power support to the local grid when requested.

"This installation is a cornerstone of our energy strategy," concluded Johansson. "It provides us with the operational flexibility we need today and the scalability for tomorrow. The decisive factors were technical prowess, climate resilience, and regulatory compliance—all clearly delineated in the product's proven capabilities."

The project stands as a benchmark for industrial energy modernization in Northern Europe, demonstrating how carefully specified and procured power conversion technology can catalyze a more sustainable and resilient energy infrastructure.
