Abstract
A system for providing power from a direct current (DC) source to the power grid. The system includes a first inverter with an input and an output. The input is adapted to connect to the DC source. A first switch disposed between the output and the power grid. A second inverter with a DC terminal and an AC terminal, the AC terminal is adapted to connect in parallel with the output of the first inverter. A battery adapted to connect to the DC terminal of the second inverter. A second switch connected between the DC terminal of the second inverter and the input of the first inverter. The second switch also operatively connects the DC source to the battery. The system may further include a charging circuit adapted to be disposed between the input and the DC terminal and a load adapted to connect to the output.
