The utility model provides a system for restrain parallel inverter system disturbance, includes two at least parallelly connected contravariant modules that set up, the contravariant module includes power supply circuit, inverter main circuit and control circuit. All include an active disturbance rejection controller module in every contravariant module, inside with the outside comprehensive disturbance of observation system in real time of the active disturbance rejection controller module of setting gives corresponding compensation to make active disturbance rejection controller module can restrain the disturbance between disturbance that the error that exists because of maximum power point tracking control, phase -locked loop and dc -to -ac converter side inductive current brought and two the contravariant modules, thereby control contravariant module parallel system's disturbance be the zero. The utility model discloses simple structure, it is convenient to realize, has both remainoriginal parallel system's characteristics, has eliminated the parallel machine disturbance again, through inside with the outside comprehensive disturbance of observation system and give corresponding compensation to control inverter parallel system's disturbance is zero.
