Abstract: A standalone and grid-tie power inverter includes a DC-to-AC converter, an output circuit electrically connected to the DC-to-AC converter, and a control unit electrically connected to the DC-to-AC converter and the output circuit. The DC-to-AC converter converts a DC power source into an AC power output. The output circuit includes a grid-tie switch for connecting the AC power output to a grid or isolating the AC power output from the grid. The control unit instructs the DC-to-AC converter to provide the AC power output based on a command signal and a feedback signal from the DC-to-AC converter. The control unit controls the grid-tie switch to switch the standalone and grid-tie power inverter between a standalone mode and a grid-tie mode.
