How to measure ground current of photovoltaic panels

Best Practices in PV System Ground Fault Testing — Mayfield

Using a digital multimeter (DMM), technicians should measure voltage from positive to negative, positive to ground, and negative to ground. The readings will return different values, which

How to test and troubleshoot solar PV systems

For reference, you typically measure these values close to standard test conditions (STC) in the field and then compare them to the solar panel manufacturer''s test results.
