The invention discloses a control method of an independent and parallel dual-mode running invertor. When the invertor independently runs, the reference signal ur transmitted by a controller is taken as the voltage reference, and the stable voltage is output; when the invertor runs in parallel, the voltage of an electric network is taken as the voltage reference, the controller transmits a current reference command to the invertor, the current control is performed to the invertor through the command, the stable current is output, and the power is input to the electric network; and when the independent running of the invertor is transformed into parallel running, besides the capacitive current compensating link, the independent and parallel dual-mode smooth switching can be realized, so that the same inverter can run in the two modes.
