The world's first all-inclusive solar PV specific installation electrical safety testing kit from Seaward. In order to fulfil the requirements of the Microgeneration Certification Scheme, a number of electrical tests must be performed on a Solar PV Installation. The required tests are now defined in detail in a recently published standard, IEC 62446, and include earth continuity between any exposed metal parts and the protective earth in the building, the insulation resistance between the DC conductors and exposed metal parts, the open circuit voltage of each PV string, short circuit current of each string and an operational test. Ordinarily, this requires the use of three separate test instruments: a continuity/insulation resistance tester, a digital multimeter and a DC current clamp. The test leads supplied with these instruments are not designed for direct connection to the interconnections commonlyfound on PV systems, resulting in the installer using makeshift test adaptors to connect to the PV system and to short circuit the PV strings for short circuit current measurement. This poses the risk of accidental contact with live DC conductors or damage to the PV panels.
