Portugal has emerged as a European leader in renewable energy, with over 60% of its electricity generated from green sources like solar and wind. This rapid transition has created a critical demand for high-performance DC Overcurrent Protection Units and DC Residual Current Devices (RCDs). Whether it is the vast solar farms in the Alentejo region or the burgeoning EV charging network in Lisbon and Porto, the safety of DC circuits is paramount.
Foshan SDEV Charger Co., Ltd., as a premier factory and exporter, provides specialized solutions tailored for the Portuguese market. Our Type B RCDs are specifically designed to detect smooth DC leakage currents, which are common in modern solar inverters and EV charging stations but cannot be detected by standard Type A devices.

"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 Portugal's aggressive expansion of the MOBI.E network, Type B RCDs have become mandatory. Our units provide the necessary 6mA DC leakage protection required by European standards (IEC 62955) to prevent electrical fires and equipment damage.
Portuguese homeowners are increasingly adopting "Autoconsumo" (self-consumption) solar systems. Our compact DC Overcurrent Protection Units ensure these residential systems remain safe during lightning surges or internal circuit faults.
Heavy industries in Portuguese industrial hubs require high-current DC temperature rise testing and precision monitoring. We export specialized DC current measuring devices to ensure industrial stability and safety.
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 increases brand awareness for your company in Portugal’s competitive energy sector.
To achieve our goal, our factory and products comply with UL, SAA, CB, CE, TUV, ISO, and RoHS standards. We understand the specific regulatory requirements of the DGEG (Direção-Geral de Energia e Geologia) and the Portuguese Electrical Installations Regulations (RTIEBT).
In the context of Portugal’s energy landscape, the integration of high-capacity DC systems is not just a trend but a foundational shift. As a factory and exporter, we have observed that Portuguese electrical contractors are moving away from traditional Type AC or Type A RCDs for solar and EV installations. Why? Because the modern electronic power conversion equipment—such as the high-frequency inverters used in Portugal’s large-scale solar plants in Beja or Évora—can generate "smooth" DC fault currents.
Standard RCDs fail to detect these DC currents because the DC leakage "blinds" or saturates the transformer core of the RCD, preventing it from tripping even when a dangerous AC fault occurs. This is where our Type B DC Residual Current Devices become indispensable. They are engineered with advanced sensor technology to monitor both AC and DC leakage simultaneously, providing total protection for human life and infrastructure.
Moreover, Portugal's geographical position makes it prone to atmospheric discharges. Our 1500V DC Surge Protective Devices (SPDs) are designed to handle the intense voltage spikes associated with these events, protecting the multi-million Euro investments in PV arrays. We provide tailored solutions for exporters in Portugal who distribute to the PALOP countries (Angola, Mozambique, etc.), leveraging Portugal’s strategic position as a logistical hub for Lusophone markets.
Our R&D team continuously monitors market trends, leading to our first UL508i listed patented DC switch 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 long-term partnerships with Portuguese renewables companies, EPC contractors, and electrical wholesalers. By combining our 30 years of manufacturing expertise with local market knowledge, we ensure that the "Green Transition" in the Iberian Peninsula is built on a foundation of safety and reliability.
From the high-current temperature rise testing of industrial transformers in Coimbra to the installation of residential wallboxes in Braga, SDEV Charger provides the critical "safety valve" for the DC ecosystem. We invite Portuguese distributors to explore our comprehensive range of ISO9001-certified overcurrent and residual current protection units, designed for the future of energy.
