Photovoltaic Inverter As the core equipment of the photovoltaic power generation system, the inverter is to convert the variable DC voltage generated by the photovoltaic module into the mains frequency ALTERN, which is one of the important system balances in the photovoltaic array system. Oritron Solar Ltd. also can provide the photovoltaic inverters by cooperation with first-class inverter manufacturers such as SUNGROW. Centralized inverters are one of the main types of photovoltaic inverters which are generally used in large power generation systems such as large plants with uniform sunlight, desert power stations, and ground power stations, and the total power of the system is large, generally above megawatts. Centralized inverters have a variety of advantages including convenient management, high reliability, high quality of electricity power, and all kinds of functions of centralized inverter are complete leading to the high safety of power station and good grid regulation. Meanwhile, from the economic perspective, the centralized inverter has low cost because of high integration and density. SG3125HV-MV Product characteristics: ??Efficient power generation. Integrate connection design and low degradation, the efficiency is 98.55%, and the power generation is increased by more than 1%. Patented PID repair technology, component performance 100% recovery (invention patent: ZL201310232014.1). ??Intelligently friendly. Meets 30ms dynamic reactive response. Unified communication interface, debugging, operation and maintenance is more convenient ??Investment reduction. ??High reliability. 24h online AC insulation monitoring for safety, IP55 protection for harsh environments.
