PV inverter with micro/nano-grid integration capability

摘要

Systems, methods, and devices relating to inverters. A control system for use with photovoltaic panel coupled inverters controls the function and operation of the inverter based on the voltage at the point of common coupling. The inverter is operated in either current control mode or in voltage control mode based on whether or not the inverter is coupled to a grid or whether other energy sources are available to control the voltage at the point of common coupling.
