With the launch of the latest 1500 V PV string inverter SG350HX, Sungrow offers a new market-leading solution that features a maximum output power of 352 kW. Thus, compared to Sungrow’s last generation inverter, the new inverter offers a significant increase in output power of about 40 per cent. The inverter comes with products from Infineon Technologies AG contributing to this performance increase: the customized EasyPACK™ power modules equipped with the newly released CoolSiC™ MOSFET, the latest generation CoolSiC diode along with the latest TRENCHSTOP™ chip technologies.
“Sungrow is dedicated to paving the way for global carbon neutrality with growing technical innovations. We are accelerating our steps to fulfil the corporate mission of ‘Clean power for all’,” said James Wu, Vice President of Sungrow. “To make this possible, the new SG350HX redefines the super-high power string inverter and helps Sungrow’s customers to reduce the cost of energy.”
“We are very pleased to continue our successful collaboration with Sungrow and leverage our technology expertise in the area of renewable energy,” said Dr. Peter Wawer, President of the Industrial Power Control Division of Infineon. “Leveraging our expertise on technology and production allows us to tailor solutions based on customer needs while giving full support during ramp-up.”
The inverter supports a DC/AC ratio of up to 1.8 and is highly compatible with 182 mm and 210 mm large-sized high-efficiency modules with a maximum input current of 20 A. This allows to use solar modules with power ratings of 600 W and higher. The device can operate stably in extremely weak grid conditions.
Weighing only 110 kg, the inverter features twelve MPPTs (Maximum Power Point Tracking) at 40 A. With two strings connecting to one MPPT, there is no threat of a string reverse connection. Each one helps to increase the power density by approximately 28 per cent compared to the previous generation. Thanks to smart-forced air-cooling technology and IP66 protection, the solution can be installed in harsh conditions.
