The Slovenian measuring equipment manufacturer Metrel has released a new multifunctional safety tester for electrical installations for PV systems. The MI 3114 PV tester can test systems with a maximum voltage of up to 1,500 V and a maximum short-circuit current of 40 A.
“It supports testing in accordance with the IEC 62446-1 standard and supports all measurement procedures, which include all Category 1 tests,” the company said. “This includes PV-specific measurements such as insulation resistance measurements of PV strings, Isc and Uoc measurements, as well as the calculation of measurement results to STC values and comparison with nominal values given by the PV module manufacturer.”
The product has various accessories and a “standard” or “pro” configuration. The latter includes an external Wi-Fi unit for measuring irradiation and cell temperature of PV modules. The MI 3114 is controlled locally via a color touch screen.
The safety tester measures 31 cm x 13 cm x 25 cm and weighs 4.4 kg. The optional remote control weighs 1 kg and measures 14 cm x 8 cm x 23 cm. Both operate at altitudes of up to 4,000 meters.
