Under normal circumstances, the absolute value of the voltage to ground at the positive or negative terminals should be between 100 ~ 1000 V, gradually dropping within 20V of the measurement.. Under normal circumstances, the absolute value of the voltage to ground at the positive or negative terminals should be between 100 ~ 1000 V, gradually dropping within 20V of the measurement.. Once in the AIO and charging in sunlight, it shows that it drops to about 290-300VDC when I use the app to see input voltages. I assume that's normal. So now I measured PV+ at the terminal block against the ground lug in the same box, and there was 30VDC present. I got nervous and disconnected. . Electrical systems in the U.S. (including PV systems) are generally solidly grounded to limit the voltage with reference to ground during normal operation, and to prevent excessive voltages due to surges from lightning or unintentional cross connections with higher voltage lines. In PV systems, the. . Measure the voltage between the positive terminal and the ground potential (PE). Measure the voltage between the positive and negative terminals. All measured voltages are stable. The sum of the two voltages to ground. . may increase the risk of fire hazards.
