NSG-1000NG Solar Inverters


This megawatt station has been specifically designed to meet the requirements of the Chinese market. With our latest compact station solution, which combines two of our latest 500kW inverters, as well as DC and AC power distribution, monitoring and protection systems, we kept its size as small as possible. It also allows most effective installation and low maintenance costs.
