Metrel MI 3108 EurotestPV Electrcal and PV Installation Tester

MI 3108 EurotestPV is a combined photovoltaic tester and electrical installations safety tester. It enables complete testing of electrical installations according to EN 61557 standards and in addition performs all necessary tests required on single-phase photovoltaic (PV) installations. This includes all of the tests as required by EN 62446, but also includes I - U characteristic, Calculation of STC values and power measurements on Inverter’s DC and AC sides. The unit is designed for the demanding working conditions (up to 1000 V, with 15 A DC). To greatly improve user safety the MI 3108 EurotestPV comes with the PV Safety Probe which ensures safe disconnection every time.

Measuring functions

Photovoltaic installations:
Measurements on DC side of PV installation:

• Voltage, current, power;
• Uoc (Open Circuit Voltage) and Isc (Short Circuit Current);
• I - U curve of PV modules and strings;
• Irradiance;
• Module temperature.

Measurements on AC side of PV installation (power quality):

• Voltage, current, frequency, power, PF, energy, harmonics;
• Efficiency of PV module, inverter, PV system calculation.

Electrical installations:

• Insulation resistance;
• Continuity of PE conductors;
• Line impedance;
• Loop impedance (sub-functions with high current and without RCD tripping);
• RCD testing (type AC, A and B);
• Earth resistance;
• AC current (load and leakage);
• TRMS voltage, frequency, phase sequence;
• Power, energy, harmonics.
