High-precision protection components engineered for North American utility standards.
The United States solar market has entered a golden era of expansion, fueled by the Inflation Reduction Act (IRA) and a nationwide transition toward decarbonization. As utility-scale projects in states like Texas, California, and Florida push the boundaries of capacity, the demand for high-reliability circuit protection—specifically Solar PV Fuses—has never been higher.
In the US industrial sector, modern solar installations are shifting from 1000V DC to 1500V DC architectures to improve efficiency and reduce BOS (Balance of System) costs. This technological leap requires fuses that can handle higher interrupt ratings and offer superior thermal management. Our factory focuses on exporting these specialized components to meet the rigorous safety demands of American EPC (Engineering, Procurement, and Construction) firms.
Protecting centralized and string inverters from overcurrent in harsh American climates.
All products are designed with UL 248-19 compliance in mind for seamless US grid integration.
Foshan SDEV Charger Co., Ltd. is a trusted manufacturer of protective components for photovoltaic systems across the globe. 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 to the United States and North American markets.
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.
Large-scale solar farms in the Arizona desert require fuses with extreme temperature stability. Our ceramic fuses provide 1500VDC protection specifically for these industrial-grade environments.
The US is leading the world in Solar + Storage. Our PV fuses serve as the critical first line of defense in battery string protection, preventing catastrophic failures during DC faults.
As smart grids become the standard in states like New York, our fuse holders are integrated into intelligent combiner boxes to facilitate real-time system health diagnostics.
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 and cutting-edge PV protective products. We aim to create a long-term partnership with many US renewables companies.
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.
Our solar PV fuses undergo rigorous cycle testing to ensure they can withstand the diurnal temperature swings common in the Midwest and Southwestern United States, ensuring a 25-year service life matching the PV panels themselves.
