4 FAQs about How to measure the resistance value of a solar container communication station

How do you measure the insulation resistance of a PV inverter?

One method is to measure the insulation resistance of each panel with respect to ground. This indirectly also measures the leakage current. The measurement is usually done before the turning on of the PV inverter or at least once or twice per day. For a 1000 Vdc system, normal practice requires insulation resistance to be more than 1 MΩ.

Do PV systems pass IEC standards for insulation resistance testing?

To pass International Electrotechnical Commission (IEC) standards for insulation resistance testing, PV systems with an open circuit voltage rating greater than 120 Vdc must have an insulation resistance greater than 1 MΩ. The term “Megger” is often used in the field to describe the insulation resistance test.

Do PV systems need insulation resistance tests?

To pass International Electrotechnical Commission (IEC) standards for insulation resistance testing, PV systems with an open circuit voltage rating greater than 120 V DC must have an insulation resistance greater than 1 MΩ. How are insulation resistance tests performed? Insulation resistance tests place a high voltage on the components under test.

When do I need an IR test for a PV array?

During commissioning and maintenance checks, running many insulation resistance tests with your IR tester on source-circuit conductors in a PV array is common. A test fails when insulation resistance is below 1 MΩ per IEC standards for grid-tied PV systems.
