Claim 0:
1. A system for feeding AC power to a power grid, the system comprising:
a DC/AC inverter;
a plurality of DC/DC converters, each DC/DC converter being directly coupled between an energy source and said DC/AC inverter;
a control system for controlling said DC/AC inverter and for controlling at least one of said plurality of DC/DC converters;, wherein
said DC/AC inverter is coupled between said power grid and said plurality of DC/DC converters;
said energy source is either a renewable energy source or an energy storage device;
for each of said plurality of DC/DC converters controlled by said control system, said control system automatically detects whether said DC/DC converter is coupled to a renewable energy source or to an energy storage device;
for each of said plurality of DC/DC converters controlled by said control system, when said DC/DC converter is coupled to a renewable energy source, said control system operates to maximize power received from said renewable energy source;
for each of said plurality of DC/DC converters controlled by said control system, when said DC/DC converter is coupled to an energy storage device, said control system controls a charge and discharge of said energy storage device.
