Abstract
A system includes a controller programmed to control an inverter to supply a power grid with a maximum amount AC electrical power while operating within an operating area that is pre-defined based on hardware limitations of the inverter. The system allows the inverter to operate with a variable low-DC voltage input into the inverter as opposed to a preset threshold DC voltage, thereby maximizing the amount of power the inverter supplies to a power grid. The inverter controller operates by prioritizing the reactive power output by the inverter over the active power output by the inverter so that the inverter is able to generate an output that meets the reactive power command from a utility and supplies the maximum amount of active power.
