Metrel MI 3108 EurotestPV Electrcal and PV Installation Tester

Model: Metrel MI 3108
   Installation Tester    Metrel


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.
