Electrical safety tester for 1,500 V photovoltaic systems

11 April 2024

A new multifunctional electrical safety tester from Slovenia-based Metrel is engineered specifically for 1,500 V photovoltaic (PV) installations.

The system provides testing in accordance with the IEC 62446 standard and supports all category 1 and category 2 tests and measurements. Users can document insulation resistance measurements of PV strings the continuity of protective Earth conductors and current-voltage characteristic measurements. The MI 3115 PV analyzer remotely records and reports measurements using a Wi-Fi unit.

Equipped with a touchscreen and a 14.4 V/4400 mAh lithium-Ion battery, the device can also measure irradiation of 300 W/m2 to 1.75 kW/m2. For insulation measurements with a maximal operational voltage (Um) of 250 V DC, the range is 0.12 MΩ to 199.9 MΩ. With an Um of 500 V DC, 1,000 V DC, and 1,500 V DC, the insulation measurements range from 0.12 MΩ to 999 MΩ. For the continuity test with a current of 200 mA, the range is 0.00 Ω to 1,999 Ω.
