Finland Solar Energy Project: 3,000 DC Circuit Breakers Supplied for Photovoltaic Systems

Project Background: Rapid Growth of Solar Energy in Finland

With the continuous expansion of renewable energy across Europe, Finland has been actively investing in solar power infrastructure to improve energy sustainability and reduce carbon emissions. Solar photovoltaic systems are increasingly deployed in commercial, industrial, and distributed energy applications. As a result, the demand for reliable DC circuit breakers and photovoltaic protection components has grown significantly.

DC circuit breakers play a critical role in solar systems by protecting electrical circuits from overload, short circuits, and reverse current, ensuring system safety and operational stability.

Customer Requirements: Reliable DC Protection for Solar Systems

In June 2024, we established cooperation with a professional solar panel energy company in Finland. The customer required high-quality photovoltaic DC circuit breakers for use in solar energy systems, including inverter protection, battery storage systems, and DC distribution cabinets.

The key requirements included stable performance under high DC voltage, long service life, compliance with international standards, and compatibility with various photovoltaic system configurations.

Product Solution: High-Performance Photovoltaic DC Circuit Breakers

To meet the project needs, we supplied 3,000 units of DC molded case circuit breakers specifically designed for solar applications. As an experienced molded case circuit breaker manufacturer and factory with over 8 years of expertise, we provided reliable and cost-effective solutions tailored to the European market.

Our DC circuit breakers support multiple voltage levels such as DC1000V and DC1500V, making them suitable for modern photovoltaic systems. The products feature high breaking capacity, strong arc extinguishing capability, and excellent insulation performance, ensuring safe operation in demanding environments.

These photovoltaic circuit breakers are widely used in solar combiner boxes, inverter systems, battery energy storage systems (BESS), and DC distribution panels.

Production & Delivery: Stable Supply with On-Time Shipment

With our advanced production lines and strict quality control system, we completed the production of 3,000 units within the agreed schedule. Each product underwent rigorous testing, including electrical performance testing, durability checks, and safety verification.

Our efficient logistics coordination ensured timely delivery to Finland, supporting the customer’s project timeline without delays.

After-Sales Support: Long-Term Technical Partnership

Beyond product supply, we provided continuous technical support, including installation guidance, system compatibility advice, and application optimization. Our responsive service team ensured smooth project implementation and long-term system reliability.

Thanks to our consistent product quality and professional support, the customer expressed high satisfaction and has established a long-term cooperation with us. They continue to place repeat orders on a quarterly basis, further strengthening our partnership.

Project Results: Reliable Protection for Solar Energy Systems

The DC circuit breakers have been successfully applied across multiple solar energy projects in Finland. The products demonstrated stable performance, improving system safety, reducing failure risks, and enhancing overall efficiency.

This project highlights our capability to support renewable energy applications with high-quality electrical protection solutions.
