An adaptive control method for multiple inverters in parallel and a system with multiple inverters in parallel. The method average distribute the active power of each inverter unit by means of acquiring state information of inverter units, adjusting a reference voltage output by each of the inverter units based on a deviation between the output active power and the average active power, which is calculated by the state information, re-acquiring the state information and calculating a voltage component difference and a current component difference between the inverter units based on the adjusted reference voltage, and then adaptively adjusting the virtual impedance of the slave inverter unit according to the voltage component difference and the current component difference so that the output impedance of the slave inverter unit and master inverter unit is matched.
