The Sofar Solar 50KTLX-G3 is a transformerless three-phase on-grid inverter designed for residential, small industrial, and commercial solar installations. It converts energy from solar arrays with a maximum efficiency of 98.8%, ensuring that very little power is lost during the process. To maximize energy harvest from panels on different roof orientations, it utilizes 4 independent MPPT trackers with an operating voltage range of 140-1000V and a start-up voltage of 160V. Built to withstand demanding environments, the unit features an IP65 protection rating and can operate in temperatures ranging from -30°C to +60°C. Its design includes Type II surge protection devices for both DC and AC sides, along with a prolonged AC overload capability of 110% for added system stability. The hardware is managed via an integrated cooling fan to maintain performance, while the user can monitor the system through an LCD display or a dedicated software application. Connectivity is handled through RS485, USB, and Bluetooth interfaces, with optional support for WiFi, GPRS, and 4G. The device weighs 18 kg and measures 430 x 385 x 182 mm, making it a compact solution for managing large commercial arrays. It is particularly suited for users who need a reliable grid-tied system without battery storage, offering a quiet operation with noise levels below 40dB.
