Abstract
An inverter, a method for controlling an operation mode, and an inverter system are provided. The inverter includes a detection circuit and a controller. The detection circuit is configured to detect a state of an auxiliary switch in a junction box, and send the state of the auxiliary switch to the controller. The controller is configured to determine an operation mode of the inverter based on the state of the auxiliary switch. The state of the auxiliary switch is synchronized with a state of a power switch in a first switch assembly. The state of the power switch in the first switch assembly is used to indicate a state of a power grid.
