A system and method are disclosed for controlling an inverter to provide an alternating inverter voltage to a load for a transition in which a change in active power (P) and/or reactive power (Q) within a transition time (Ttr) is carried out. The method includes converting a direct current voltage (Udc) into an alternating inverter voltage (Vinv) with a basic frequency (ω); and selecting a transition time Ttr for a change in active power (P) and/or reactive power (Q) within a load to be supplied the alternating inventor voltage. To address DC offsets, the transition time Ttr is chosen such that in an equation which is a function of the fundamental period of the basic frequency and the target phase angle after the transition between the inverter voltage Vinv and the load voltage Vn, a variable k is a small integer number between 1-8.
