Thailand has emerged as a leader in Southeast Asia's renewable energy transition. With the implementation of the Power Development Plan (PDP 2018-2037), the nation aims for 30% renewable energy consumption. This surge has created a massive demand for robust PV Junction Boxes and DC Residual Current Devices (RCDs) capable of withstanding the tropical humidity and high-temperature environments of regions like Rayong and Samut Prakan.
Within the Eastern Economic Corridor (EEC), smart factories are integrating high-voltage DC systems. As an experienced PV Junction Box exporter to Thailand, we recognize that Thai industrial standards (TIS) are increasingly aligning with International Electrotechnical Commission (IEC) standards, specifically requiring Type B RCDs for EV charging and solar installations to ensure protection against smooth DC residual currents.
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 Bangkok and surrounding provinces, the "Solar Rooftop" subsidy has led to thousands of home installations. Our DC RCDs and PV Junction Boxes are designed for "Plug & Play" reliability, ensuring Thai homeowners are protected from leakage currents even during the heavy monsoon seasons. High-quality RCDs are not just a component; they are a safety necessity in the high-humidity Thai climate.
Thailand's push to become the "Detroit of Asia" for EVs means charging stations are appearing at malls, offices, and highways. DC RCDs (Type B) are critical here. Unlike standard AC breakers, our devices detect high-frequency DC leakages that occur during EV battery charging, preventing electrical fires and ensuring public safety at PTT and PEA charging hubs.
Thailand’s innovative floating solar farms (like those at Sirindhorn Dam) require junction boxes with extreme IP ratings and UV resistance. Our products are engineered for these harsh environments, where moisture ingress is a constant threat. The salt-mist resistance of our PV components makes them ideal for Thailand’s coastal solar projects.
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.
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 renewables companies.
As an leading exporter to the Thai market, we have observed a significant shift in technical requirements. Standard RCDs (Type AC or A) are often insufficient for modern solar inverters and EV chargers. The move towards Type B Residual Current Devices is driven by the need to detect smooth DC leakages. In Thailand's industrial zones, where power quality can fluctuate, Type B devices provide the only reliable protection against blind tripping and equipment damage.
Ultra-fast Trip Time
Thai Climate Ready
High Voltage Capacity
Local Standards
As a specialized factory and exporter focusing on the Southeast Asian market, we understand the unique challenges faced by Thai EPC contractors and solar installers. The high ambient temperature in provinces like Kanchanaburi or the humidity in Phuket can significantly degrade electrical components. Our PV Junction Boxes are manufactured using premium-grade PPO/PC materials that are both UV stabilized and flame retardant, ensuring a lifespan exceeding 25 years.
Furthermore, our DC RCD solutions solve the "blindness" problem inherent in standard AC breakers. In an EV-focused economy like Thailand's, where companies like BYD and Great Wall Motor are establishing manufacturing hubs, the electrical infrastructure must be future-proofed. Our Type B RCDs ensure that even the smallest DC leakage is detected, preventing damage to expensive vehicle electronics and ensuring the safety of personnel.
We provide full documentation and compliance certificates required for project approval by the MEA (Metropolitan Electricity Authority) and PEA (Provincial Electricity Authority). By partnering with us, you gain access to 30 years of manufacturing excellence combined with localized insights into Thailand's energy sector. Whether you are building a solar farm in Korat or a residential complex in Bangkok, our protection devices offer the reliability you need.
