Sungrow says its new SG150CX inverter, which was launched this week at the World Future Energy Summit in Abu Dhabi, achieves an efficiency of 98.8% and a European efficiency of 98.2%. It is designed for commercial and industrial (C&I) applications.
Chinese inverter manufacturer Sungrow has launched a new inverter for 1,000 V C&I applications at the World Future Energy Summit (WFES) exhibition in Abu Dhabi, United Arab Emirates.
“The SG150CX inverter is designed for exceptional performance, safety and reliability,” a company spokesperson said pv magazine. “It is equipped with Arc Fault Circuit Interrupter (AFCI) 3.0 technology and offers an extended cable detection range of up to 450 meters, increasing operational safety.”
The system measures 1,025 mm x 795 mm x 360 mm and weighs 100 kg. It delivers 210 kW PV input power, with a maximum input voltage of 1,100 V and a nominal input voltage of 600 V. The MPPT voltage range extends from 180 to 1,000 V, while the maximum PV input current reaches 336 A.
The new product includes seven independent MPPT (Maximum Power Point Tracking) inputs and three PV strings per MPPT. It delivers a rated AC output power of 150 kW and supports a rated AC voltage range of 320 V to 480 V.
Sungrow said the transformerless inverter offers 98.8% efficiency and 98.2% European efficiency. It features IP66-rated protection, operates in temperatures from -30 C to 60 C, and includes integrated surge protection for both DC and AC.
“With a maximum Power Point Tracking (MPPT) input current of 48 A, the SG150CX ensures compatibility with high-current PV modules, significantly increasing system efficiency,” the spokesperson said. “It is also equipped with smart switches, allowing faulty strings under the same switch to be disconnected while other strings remain operational, drastically reducing power generation losses.”
The system is also equipped with grid monitoring, DC reverse polarity protection, leakage current protection, earth fault monitoring, DC switch, PV current monitoring, DC arc interrupter and PID recovery function.
