Utility-scale solar PV pushes into higher AC voltages
By Allen Austin, ABB Inc. The evolution of high-efficiency solar photovoltaic (PV) string inverters is driving a shift toward higher AC voltages in utility-scale solar applications. Using string inverters in solar plants rated at 20 megawatts and below can be extremely beneficial. With output voltages now as high as 1000VAC, the same amperages will yield …
