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.
The transition toward decentralized green energy has triggered unprecedented demand for robust solar installations worldwide. As utility-scale solar farms and commercial rooftops scale rapidly, the reliability of DC-side protection components dictates overall system ROI and safety compliance.
Driven by aggressive net-zero carbon pledges, North American, European, and Asia-Pacific markets demand ultra-reliable solar deployment infrastructure capable of withstanding extreme environmental stressors.
System voltages are ascending from 1000V to 1500V DC to curtail balance-of-system (BOS) costs. This engineering paradigm requires advanced insulation materials, fault arc detection, and high-amp DC disconnectors.
Modern installations seamlessly integrate photovoltaic generation with energy storage systems (ESS) and electric vehicle (EV) charging infrastructure, highlighting the need for unified, certified power management components.
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. Every batch undergoes stringent thermal cycling, mechanical endurance, and dielectric withstand testing prior to international shipment.
Different geographic and climate terrains pose distinct operational hazards to solar installations. Our components are architected with application-specific engineering adaptations.
High-capacity commercial installations require stringent fire safety protocols. Our IP66-rated DC disconnectors and smart combiner boxes prevent electrical arcing and secure continuous facility operations under peak irradiance loads.
Utility farms deployed in arid or high-temperature deserts demand robust UV-resistant connectors, corrosion-proof enclosures, and high-voltage fuse protection that withstand thermal drift and heavy wind loads.
Coastal and mountainous deployments face severe salt-fog corrosion and sub-zero freeze cycles. SDEV utilizes marine-grade stainless steel housings and specialized sealing compounds to ensure 25+ years of operational durability.
From portable camping power storage units to remote off-grid telecom stations, our compact DC protection modules and PoE power supply units provide dependable energy regulation in mobile configurations.
Achieving our goals comes 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. By combining continuous engineering feedback loops with advanced simulation software, we shorten time-to-market for tailored OEM/ODM solutions.

With over 30 years of electrical engineering heritage, SDEV combines specialized in-house R&D with strict international manufacturing compliance (UL, TUV, CE, ISO). We pioneered China's first UL508i listed patented DC switch, delivering uncompromised safety and reliability to global renewable energy developers.
Photovoltaic systems operate under high-voltage direct current (DC) which does not naturally quench arcs when interrupted. High-quality DC isolator switches, fuse holders, and SPD surge arresters protect equipment from lightning surges, prevent electrical fires, and ensure safe maintenance compliance.
Yes. Our latest generation of solar PV disconnector switches, smart combiner boxes, and waterproof connectors are specifically engineered for high-efficiency 1500V DC utility solar farms, helping lower balance-of-system (BOS) installation costs worldwide.
Every production batch undergoes rigorous automated optical inspection, thermal endurance testing, and dielectric withstand verification. Our facilities operate under strict ISO quality control protocols, holding valid UL, SAA, CB, CE, TUV, and RoHS certifications.
