Power system and method for earth detection and calibration of power meter

Abstract

A power system and a method are for earth detection and calibration of a power meter. A power system includes an energy supply module, an inverter module, a sensing module, a control module, and an input module. The control module enters into a earth detection and calibration setting mode when the earth detection light of the power meter lights up, and stores a calibration setting value input by the input module according to one of the working conditions, so that the control module adjusts the inverter module accordingly based on the stored calibration settings, forcing the earth detection light of the power meter to go out.
