ABB-PVS8001700-TB2-Centralized (String) Photovoltaic Inverter | PVS8001700-TB2-Zhangzhou Fengyun Electrical Equipment Co., Ltd.

The technology is based on ABB's wind power transmission platform (ACS800/ACS880 inverter technology), with decades of industry experience transferred to the photovoltaic field. The topology is a single converter (unlike the dual converter DC bus structure of industrial transmissions), and it is suitable for large-scale ground power plants, distributed, residential, and commercial applications.

　　The PVS8001700-TB2 belongs to the ABB PVS800 series of centralized photovoltaic inverters, with a rated power of 1,700 kW (1.7 MW), making it one of the high-power models in this series. ABB classifies it as a "Central Inverter," but some industry classifications also refer to it as a "string inverter"—here, "string inverter" refers to a topology where multiple MPPT strings are connected in a combined manner, rather than the currently mainstream low-power string inverters (such as the 25kW-class products of the Huawei SUN2000 series).
