How to measure the ground voltage value of photovoltaic panels
Disconnect the DC switch of each PV string connected to the inverter, and use a multi-meter to measure the voltage of the PV+ to ground and PV- to ground of each string.
Disconnect the DC switch of each PV string connected to the inverter, and use a multi-meter to measure the voltage of the PV+ to ground and PV- to ground of each string.
Using a digital multimeter (DMM), technicians should measure voltage from positive to negative, positive to ground, and negative to ground.
