Photovoltaic DC 2000V technology refers to the technology of transmitting and applying the DC power generated by photovoltaic modules at a voltage level of 2000V in photovoltaic power generation systems. Its working principle is based on the basic principle of photovoltaic power generation, that is, using the photovoltaic effect. When sunlight shines on photovoltaic modules, photons interact with electrons in semiconductor materials, allowing electrons to obtain enough energy to generate electrons and holes that move in a directional manner under the action of the electric field to form DC power. In the photovoltaic DC 2000V system, through special circuit design and component selection, the low-voltage DC power output by photovoltaic modules is boosted and transmitted in the form of 2000V high-voltage DC power. In photovoltaic systems, the improvement of voltage levels is an important direction of technological development. From the early lower voltage levels, it has gradually developed to the 1500V system that is now widely used. At present, photovoltaic DC 2000V technology is gradually emerging. Compared with the traditional 1000V and 1500V systems, photovoltaic DC 2000V has significant advantages. In theory, higher voltage can effectively reduce the current, thereby reducing the resistance loss during the transmission process and improving the overall efficiency of the system. From the perspective of voltage level, 2000V is significantly higher than 1500V and 1000V. In terms of power transmission, according to the power formula P = UI (where P is power, U is voltage, and I is current), under the same power transmission requirements, the higher the voltage, the smaller the current. According to Joule's law Q = I²Rt (where Q is heat, i.e., lost energy, I is current, R is resistance, and t is time), the reduction in current will greatly reduce the resistance loss in the line. Under the same line resistance and transmission time, the line loss of the 2000V system can be significantly reduced compared to the 1500V system. This can bring considerable economic benefits to large-scale photovoltaic power stations. In addition, the 2000V system also has certain advantages in equipment cost and floor space. Due to the reduction in current, thinner cables can be used, reducing the cost and weight of the cables, while also reducing the space required for cable laying and the difficulty of construction. At present, technologies such as artificial intelligence, digital twins, and cloud computing are constantly innovating, digital technology is deeply integrated with new energy system technology, and application scenarios are constantly enriched, achieving cost reduction and efficiency improvement throughout the photovoltaic life cycle. 2000Vplug-in SPDs used in combiner boxes,PCB type SPDs in inverters, line lightning arresters, and supporting monitoring terminals have emerged. Following the development trend of the industry,Anhui Jinli has m...
