Referring to fig. 2 and 3, the present embodiment provides a control method of a novel intelligent inverter, which is used for controlling the novel intelligent inverter.
Specifically, the control method comprises the following steps:
step S1, the novel intelligent inverter works normally;
step S2, detecting whether the novel intelligent inverter is in an idle state;
