This application discloses an inverter, an inverter system, and a method. The inverter includes an inverter circuit and a controller. When at least one of the following preset conditions is met, the controller adjusts at least one of parameters including an operating frequency, an operating voltage, and an operating current of the inverter, to increase a loss of the inverter, where the at least one preset condition is as follows: An output power of the inverter circuit is lower than a preset power, an output current of the inverter circuit is lower than a preset current, an operating temperature of the inverter is lower than a preset temperature, or an operating humidity of the inverter is higher than a preset humidity. When any one of the foregoing conditions is met, the inverter may increase the operating temperature of the inverter or reduce the operating humidity of the inverter by increasing the loss of the inverter, thereby ensuring that the inverter can operate safely and reliably. In addition, no additional heating apparatus needs to be added, which not only reduces costs of the inverter, but also does not need to change an original structure design of the inverter.
