The invention relates to an inverter decoupling method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring at least one candidate switch state of a decoupling switch included in a decoupling circuit of a target inverter; in different candidate switch states, predicting voltage and current parameters of an energy storage element in the decoupling circuit to obtain predicted parameter values; selecting a target switching state corresponding to the target inverter from different candidate switching states according to each prediction parameter value; and performing on-off control on a decoupling switch in the decoupling circuit according to the target switch state. When the decoupling switch in the decoupling circuit is controlled to be opened and closed according to the target switch state, the target inverter can achieve the purpose of balancing instantaneous power, the service life of a power generation system corresponding to the target inverter is prolong
