A grid-connected energy storage system capable of increasing the efficiency of a converter and a method of controlling the system are disclosed. In one aspect, the system includes a plurality of converters for converting power generated by each of the plurality of power generation modules into DC power at a voltage level, a plurality of series switches connected to the plurality of power generation modules, and a plurality of parallel switches configured to selectively connect each of the power generation modules to each and every other of the power generation modules. The system also includes a controller configured to control the switches in order to selectively connect each of the power generation modules to at least one selected converter. |
