Abstract
A power supply system includes a power conditioning apparatus, a transformer, and a controller. The power conditioning apparatus includes an inverter circuit, at least one grid-connected switch, a voltage-to-ground detector. The inverter circuit is configured to connect to the inverter circuit is configured to connect to the transformer through the at least one grid-connected switch, and the transformer is configured to connect to a power grid. When one grid-connected switch is turned off and turned on, the voltage-to-ground detector detects voltage to grounds of the power conditioning apparatus to obtain a first voltage value and a second voltage value respectively. The controller outputs alarm information for grounding of a neutral wire of the transformer or controls the power conditioning apparatus to stop working when a difference between the second voltage value and the first voltage value falls within a preset voltage range.
