<p>Disclosed is a data sharing system between a master inverter and a slave inverter, in which input/output ports between the master inverter and the slave inverter are selectively shared through background communication through Controller Area Network communication. In a data sharing system in which input/output devices between a mater inverter and a slave Inverter are shared, the master inverter determines the presence of outputting output data through the slave inverter, based on information on the presence of sharing a slave input/output device included in the slave inverter.
