The high-power 50kW grid tie solar inverter converts 200-820V DC to 3 phase 380 volt, 460 volt and feed the power into the grid, high reliability due to perfect protection function, powerful communication interfaces, easy operation and installation. In this article, I will detail the comprehensive design process of a 50KW three-phase grid-connected solar inverter, focusing on hardware circuit design, control strategies, and software implementation. The maximum input current of each MPPT is 40A, also compatible with 600W+ PV modules in the global markets. Combined with 6 string of DC input and precise algorithm, it's the ideal option for rooftop. S5-GC (25-50)K three-phase series string inverter adopt 3/4 MPPT design to provide a more flexible configuration scheme with a smaller environmental impact rate and higher generation efficiency. By integrating high-efficiency solar panels, commercial-grade grid-tied inverters, and optimized electrical and mounting components, the system. Pure sine wave three phase 50kW grid tie inverter without transformer for on grid solar system. 3 phase grid tie inverter has a wide input voltage range of 200-820V and wide output range of 280V-480V, max DC input voltage to 850V, multi-language LCD, 2 way MPPT, MPPT efficiency more than 99%.
