As the world pivots toward renewable energy and electrification, the role of DC Circuit Protection Devices has transitioned from a niche component to a critical industrial backbone. Unlike AC circuits, DC currents are notoriously difficult to interrupt due to the lack of a "zero-crossing" point, requiring advanced arc-extinguishing technologies found only in specialized DC circuit protection factories.
From massive utility-scale solar farms to residential Electric Vehicle (EV) chargers, the demand for reliable 1500V DC protection is skyrocketing. Global industries are moving toward smarter, connected protection devices that not only trip during faults but also monitor health and energy performance in real-time.
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.
With the inheritance of decades in the research and production of DC protection products, we are continuously dedicated to the EV charging field. Through our focus on solar DC protection design, production, and marketing, we bring brand-building PV protection solutions to international partners.

To reduce system losses and BOS costs, the global solar industry is shifting from 1000V to 1500V. Our factory specializes in high-voltage DC breakers and isolators designed for this harsh environment.
Modern protection requires multi-circuit monitoring. As seen in our Acrel series, smart combiner boxes now integrate remote monitoring to predict failures before they happen.
EV charging stations require specialized RCD and RCBO components to handle both AC leakage and DC residual currents (Type B RCDs), ensuring total user safety.
Procuring from a Chinese leader like SDEV offers more than just competitive pricing. Our ecosystem provides:
Protecting home energy systems with miniature circuit breakers and residual current devices that fit standard DIN-rail consumer units.
Industrial-grade RCBOs and DC Isolators for high-power DC fast-charging stations, ensuring uptime and electrical safety for heavy-duty use.
DC protection for 5G base stations and remote data centers where reliable power distribution is non-negotiable.
Achieving our goals comes from formulating new products based on market demands through our in-house R&D team. With our cutting-edge PV protective products and EV chargers, we aim to create long-term partnerships with renewable companies worldwide.
