Abstract:
1. A battery free off-grid solar inverter system, the battery free off-grid solar inverter system comprising: an inverter for converting a direct current voltage provided by a solar panel into an alternating current voltage, the inverter having an input terminal, an output terminal, and a control terminal, wherein 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 outputting the alternating current voltage; and a controller 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, wherein the controller stops increasing the alternating current voltage when the direct current voltage is lower than a predetermined direct current voltage value.
