Solar Solutions Düsseldorf Openning! PROJOY Shines in Germany with Safety Products for PV Industry

On December 3rd–4th local time, Solar Solutions Düsseldorf 2025 kicked off grandly at the Düsseldorf Exhibition Centre in Germany. Projoy Electric made a strong appearance with its full range of star products, showcasing its leading technology and innovations in rapid shutdown, optimizers, isolators, and PV distribution boxes.

The PROJOY PEFS-EL series string-level firefighter safety switch is an innovative system solution developed to address safety issues in PV systems. It can quickly cut off power in emergencies, protecting the system from potential electrical risks. The PEFS-EL series offers multiple current ratings and optional 1–10 string configurations to meet diverse customer needs. Equipped with a high-precision temperature sensor, it automatically monitors ambient temperature and shuts down when temperatures exceed 70°C. The built-in DC isolator features a dedicated arc-extinguishing device capable of quenching arcs within 5ms. This product, with its rapid response and efficient management, has been widely adopted by global customers, providing solid protection for the safe operation of PV systems.

PROJOY's PEDS series isolator in enclosure uses flame-retardant and UV-resistant materials to create an integrated waterproof enclosure. The housing offers excellent UV resistance, effectively preventing brittleness and aging for lasting reliability. The unit achieves an IP66 protection rating. In addition to standard high-quality waterproof cable connectors or MC4 connectors, industrial-grade cable glands can be optionally configured, and components such as dust plugs are included. With comprehensive accessories, it effectively prevents the intrusion of rain and dust, avoiding safety hazards like short circuits and arcs caused by moisture. Its user-friendly design and reliable quality significantly enhance system maintenance convenience and safety, making it an ideal choice for professional installers and O&M teams.

In line with the trend toward integrated PV and energy storage systems, PROJOY has displayed PV-specific distribution boxes integrated with smart meters at the exhibition. These meters support bidirectional metering and 485 communication, featuring an LCD scrolling display that shows various electrical parameters such as active and reactive power. The distribution box is constructed with high flame-retardant materials, a compact layout, and a modular plug-and-play design. It integrates not only the smart meter but also key components like RCBOs (Residual Current Circuit Breakers with Overcurrent Protection) and surge protective devices, building a full-chain safety protection system from power generation and storage to consumption.

PROJOY is committed to providing safe and reliable protection devices and solutions for PV-storage-charging systems to global customers. This exhibition not only showcased the company's strong capabilities in product innovation but also further deepened exchanges with European partners.

PROJOY keeps concentrating on innovation, drive progress, strengthen product iteration and overseas market expansion, and provide global customers with safer, more reliable, and more efficient solutions for PV and energy storage systems. We actively participate in global green energy development, contributing professional expertise to the goal of carbon neutrality.
