The world’s first all-inclusive solar PV specific installation electrical safety testing kit.
The recently published IEC 62446 international standard defines in detail the electrical test requirements of solar PV installations. These tests include ground continuity between any exposed metal parts and the protective ground 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 commonly found 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. An additional drawback is that three discrete test instruments means three annual calibration charges and hence a relatively high cost of ownership.
Seaward’s Solar Installation PV100 Test Kit includes all of the tools needed to fulfil the electrical test requirements of IEC 62446, including a world first Solar Installation PV100 handheld multifunction tester.
