Houston, Texas, traditionally recognized as the "Energy Capital of the World," is undergoing a massive transformation. As a leading Solar Array Protection Relays Factory & Exporter, we recognize Houston's pivotal role in the global energy transition. The city is not only a hub for oil and gas but has become a central point for renewable energy investment, with major corporate headquarters in the Energy Corridor increasingly adopting utility-scale solar arrays.
The industrial climate of Houston—characterized by its massive port facilities, chemical processing plants, and expansive logistics centers—requires heavy-duty, reliable PV safety switches. With the Texas sun providing abundant solar potential, the demand for high-voltage DC protection (up to 1500V) has skyrocketed. Our products are engineered to withstand the unique environmental challenges of the Gulf Coast, including high humidity and extreme thermal cycles.
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.
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.
In the Houston market, the trend is moving rapidly toward Module Level Power Electronics (MLPE) and advanced rapid shutdown devices. As the NEC (National Electrical Code) 2020 and 2023 standards are adopted throughout Texas, the necessity for reliable array-level protection has never been higher.
Modern protection relays in Houston’s industrial zones now feature AI-driven monitoring to detect arc faults before they lead to fire hazards.
Transitioning from 1000V to 1500V systems to reduce balance-of-system (BOS) costs in large-scale solar farms across the Texas plains.
Automatic rapid shutdown triggers are critical for urban Houston installations, ensuring first responders can safely manage building emergencies.
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. 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 Houston-based renewable energy contractors.
Optimizing safety for retail and office complexes with compact, IEC-approved DC isolators that fit seamlessly into existing electrical infrastructure.
