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.
Indonesia, the world's largest archipelagic state, is standing at a critical juncture in its energy transition. With the government's ambitious goal of reaching Net Zero Emissions by 2060, the demand for Solar Array Protection Relays has skyrocketed. From the massive floating solar farms in Cirata, West Java, to decentralized microgrids in the remote islands of Maluku and Papua, the reliability of DC overcurrent protection units is paramount.
As a leading exporter to the Southeast Asian market, we recognize that Indonesia's tropical climate presents unique challenges. High humidity, intense solar radiation, and frequent lightning strikes in regions like Bogor and Kalimantan require robust electrical components. Our Solar Array Protection Relays are specifically engineered to withstand these environmental stressors, ensuring that industrial solar arrays remain operational even under extreme Indonesian conditions.
The industrial landscape in Indonesia—ranging from the massive textile mills in Bandung to the mining operations in Sulawesi—is increasingly adopting on-grid and off-grid solar solutions. These systems require precise DC Overcurrent Protection Units to prevent catastrophic failures, equipment damage, and fire hazards. By integrating SDEV's advanced relay technology, Indonesian project developers can guarantee the longevity of their investments and the safety of their personnel.
Utilizing DC protection units designed for high-humidity aquatic environments, ideal for Indonesia's numerous reservoirs and lakes.
Protecting high-rise commercial buildings in the Sudirman Central Business District (SCBD) from DC surges in solar PV installations.
Ensuring stable power for off-grid communities in East Nusa Tenggara through reliable overcurrent protection and relay systems.
Providing heavy-duty DC circuit breakers and relays for manufacturing hubs in Batam and Cikarang.
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 the Indonesian market, we prioritize components that meet the SNI (Standar Nasional Indonesia) benchmarks for electrical safety, ensuring that every relay exported is ready for immediate integration into the local grid.
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.
In Indonesia, the trend is moving towards Smart Grids and Internet of Things (IoT) enabled protection devices. Our latest generation of solar array protection relays features real-time monitoring and remote diagnostics, allowing Indonesian plant managers to oversee their systems from a centralized location, reducing maintenance costs and downtime.

Send Inquiry NowWhen discussing Solar Array Protection Relays in the context of Indonesia, one must understand the technical nuances of DC (Direct Current) vs. AC (Alternating Current). In a typical solar installation in Surabaya or Medan, the solar panels generate DC power which is then converted by inverters. However, the segment between the panels and the inverter is the most vulnerable to overcurrent and short circuits. Unlike AC, DC arcs do not cross the zero point, making them much harder to extinguish. This is where high-quality DC Overcurrent Protection Units become non-negotiable.
Indonesia's Just Energy Transition Partnership (JETP) has paved the way for billions of dollars in renewable investment. However, this growth is often met with logistical and technical hurdles. For instance, the high thermal stress in regions near the equator can cause inferior protection relays to trip prematurely or, worse, fail to trip during an actual surge. SDEV's products are tested against high-temperature profiles to ensure that they provide consistent protection without "nuisance tripping."
The "Green Building" certification in Jakarta's skyscrapers is driving the adoption of solar glass and rooftop PV. For these urban applications, space-saving DC protection units are required. Our modular 12kv Indoor Vacuum Circuit Breakers and compact relay units are designed to fit into tight electrical cabinets without compromising on safety or performance. Furthermore, for the massive palm oil plantations and processing plants in Sumatra, our preheating control units and high-efficiency digital energy feedback units help in optimizing energy consumption and protecting heavy-duty machinery.
With the Indonesian government providing incentives for electric vehicle (EV) manufacturing and adoption, the infrastructure for EV charging is expanding rapidly. Every EV charging station requires robust DC protection to ensure the safety of both the vehicle's battery and the grid. SDEV has leveraged its 30 years of experience to develop specialized protection units that are now being exported to support Indonesia's "EV Battery Hub" ambitions.
Navigating international standards can be complex for Indonesian importers. SDEV simplifies this by ensuring all products meet UL (Underwriters Laboratories) and TUV certification, which are widely recognized by Indonesian state-owned utility PT PLN (Persero). Our focus on Solar Array Protection Relays Factory operations ensures that we maintain a rigorous supply chain, providing high-quality components that are both durable and affordable for the Indonesian market.
By choosing SDEV, you are not just buying a component; you are investing in a partnership backed by decades of engineering excellence. Whether you are a solar contractor in Bali, a plant manager in Bekasi, or a government developer in the New Capital (IKN) of Nusantara, our solutions are tailored to meet the rigorous demands of your projects.
