Systems and methods for increasing output current quality, output power, and reliability of grid-interactive inverters

A grid-interactive inverter configured to receive direct current and to provide alternating current to a grid, comprising:

• input terminals configured to receive a direct current;
• output terminals configured to provide an alternating output current to the grid;
• a controller;
• at least one sensor capable of measuring alternating output current provided to the grid;
• a DC-AC inverter comprising a plurality of switches controlled by control signals generated by the controller;
• wherein the controller is capable of generating the control signals that cause the plurality of the switches in the DC-AC inverter to switch a direct current in a bidirectional manner across output terminals of the grid-interactive inverter to provide an alternating output current to the grid;
• wherein the controller is capable of dynamically generating the control signals that cause the plurality of the switches in the DC-AC inverter to switch current in a bidirectional manner across the output terminals in response to the measured alternating output current to provide reactive current to the grid.
