Ensuring system integrity with high-voltage certified protection gear.
The global energy transition is accelerating, with utility-scale photovoltaic (PV) systems rapidly shifting from 1000V to 1500V architectures. This transition is not merely a technical upgrade; it is a strategic move to reduce Balance of System (BOS) costs and improve overall energy yield. A 1500V DC system allows for longer strings, reducing the number of combiner boxes, cabling, and installation labor.
However, 1500V systems demand significantly higher performance from safety components. The DC Load Break Switch 1500V serves as the critical safety heart of these systems, capable of interrupting high-voltage DC arcs that are far more persistent and dangerous than AC arcs. As of 2024, the demand for these switches has surged in North America, Europe, and the Middle East, driven by massive solar farm deployments.

Our experience of working in the electrical industry for more than 30 years allows us to create solar DC components that comply with the latest DC standards. Through our focus on solar DC protection design, production, and marketing, we can bring brand-building PV protection solutions.
With the inheritance of 30+ years of experience in the research and production of DC protection products, we are continuously dedicated to the EV charging field. In recent years, SDEV has attentively invested resources in research on EV-related products, successively manufacturing other types of products, thus reaping wide market popularity across the world.
Stay ahead of the curve with insights into the DC switchgear market.
Global safety standards (like NEC 2020) are mandating array-level and module-level rapid shutdown. Modern DC load break switches are now integrating electronic triggers for emergency responders.
Engineers prefer modular "plug-and-play" DC disconnects that fit seamlessly into compact combiner boxes. Scalability is the key to reducing onsite installation time.
With solar farms expanding into deserts and high-altitude regions, switches must withstand UV exposure, salt mist, and temperatures from -40°C to +85°C.
Quality is the primary goal among each of our workshops since this leads to the best performance and safety for any Solar, Storage, and EV charging system. Our commitment to quality increased brand awareness for your company. To achieve our goal, our factory and products comply with UL, SAA, CB, CE, TUV, ISO, and RoHS standards.
Achieving our goals come from formulating new products based on the market demands through our in-house R&D team. Our efforts have led to our first UL508i listed patented DC switch within china and the DC-PV2 DC switch produced for the global market. With our cutting-edge PV protective products and EV chargers, we aim to create a long-term partnership with many renewables companies.
Understanding the needs of international EPCs and Wholesalers.
Compliance with UL508i and NEC 690 standards is non-negotiable. Procurement focuses on reliability for utility-scale solar farms in Texas, California, and Nevada.
High demand for IP66-rated enclosures for rooftop commercial systems and floating PV arrays in Germany, Netherlands, and Spain.
Emphasis on thermal stability and dust protection (IP67/IP68) for massive desert solar installations in the UAE, Saudi Arabia, and Australia.
