The invention relates to the electronic test field, more specifically a power unit tandem type high-voltage inverter on-site test method which comprises the steps of: 1) setting an independent power supply interface on a control circuit board of a power unit, the independent power supply interface being isolated from an internal power supply interface; 2) setting a normal operation/on-site detection change-over switch on a power unit tandem type high-voltage inverter system, the normal operation/on-site detection change-over switch being installed on the power supply output of the power unit tandem type high-voltage inverter system; and 3) setting a power cabinet on the power unit tandem type high-voltage inverter system, wherein the power cabinet is provided with a ground power supply system for supplying power for each power unit in step 1). The power unit tandem type high-voltage inverter on-site test method employs the independently installed power supply interface, the normal operation/on-site detection
