An inverter for converting electrical power from a DC voltage generator is disclosed. The inverter includes a moisture sensor inside a housing of the inverter, and a control unit for controlling the inverter connected to the moisture sensor for receiving a moisture value from the moisture sensor. The inverter also includes a heating element connected to the control unit. The control unit is configured to control the inverter based on the moisture value such that, in the case where a limit value for the moisture is exceeded, the voltage at an input of the converter unit lies below an arc-avoiding voltage value and electrical power is fed to the heating element. Furthermore, a method for operating an inverter of this type is disclosed.
