Abstract: A battery free off-grid solar inverter system includes an inverter and a controller. The inverter is used for converting a direct current voltage provided by a solar panel into an alternating current voltage. The inverter has an input terminal, an output terminal, and a control terminal. The input terminal is used for coupling to the solar panel for receiving the direct current voltage, and the output terminal is used for coupling to a load for coupling the alternating current voltage. The controller is coupled to the control terminal for gradually increasing the alternating current voltage to make the direct current voltage be gradually decreased when the battery free off-grid solar inverter system is turned on. The controller stops increasing the alternating current voltage when the direct current voltage is lower than a predetermined direct current voltage value.

The switch is connected with the first antenna and the second antenna, respectively, and it controls a conducting state between the first antenna and the second antenna.
