How to measure the insulation resistance of a solar PV system?

The IEC62446-1 standard describes two methods for measuring the insulation resistance of a solar PV system. 1. To short the positive and negative electrodes of the PV string, and measure the insulation resistance between the shorting point and earth. 2.

What is a DC test for a solar PV system?

What are the performance PV standards?

The performance PV standards described in this article, namely IEC 61215 (Ed. 2 – 2005) and IEC 61646 (Ed.2 – 2008), set specific test sequences, conditions and requirements for the design qualification of a PV module.

What is a PV continuity test?

In the standard, the test is classified into categories 1 and 2 according to the size of the PV system. Category 1 applies to all solar PV generation systems. Category 2 applies for larger or more complex systems such as mega solar power plant. If the DC side has earthing, such as a frame or equipotential bonding, a continuity test is required.
