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 global solar energy landscape is undergoing a massive shift from 1000V DC to 1500V DC architectures. This transition is driven by the need for higher efficiency, reduced balance-of-system (BOS) costs, and improved power density in utility-scale solar farms. However, higher voltages bring greater risks of electrical surges and insulation failure.
As a leading 1500V DC Surge Protector Supplier, we recognize that industrial and commercial solar installations now require robust protection that can handle intense thermal stress and high-discharge currents. Our 1500V SPDs are engineered to prevent catastrophic damage from lightning strikes and switching transients in these high-voltage environments.
The integration of IoT and remote signaling in SPDs allows plant operators to monitor the health status of surge protectors in real-time, ensuring zero downtime.
Modern 1500V DC Surge Protectors now feature advanced Thermal Disconnection technology to prevent fire hazards during end-of-life scenarios.
With the rise of BESS (Battery Energy Storage Systems), surge protection must now cover bidirectional DC flows and ultra-fast response times.
Global buyers—ranging from EPC contractors to solar wholesalers—are no longer just looking for "low price." The modern procurement demand centers on Reliability, Certification, and Lifespan.
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.
For international projects, having a supplier that understands localized standards (like the IEC 61643-31 for DC applications) is critical for passing grid inspections and ensuring long-term insurance compliance.
Our 1500V DC Surge Protectors are designed for versatility across various geographic and industrial landscapes:
Protecting centralized and string inverters in desert or high-altitude regions where lightning frequency is high and maintenance is costly.
Providing DC side protection for ultra-fast charging stations that utilize 1000V-1500V DC busbars to charge commercial fleets.
Ensuring the safety of large-scale manufacturing facilities that integrate solar power to reduce carbon footprints without risking electrical fires.
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.
