MI 3108 EurotestPV is a high-quality photovoltaic tester and electrical installation safety tester in one. The Metrel PV string tester is capable of testing low voltage photovoltaic systems. In addition, the MI 3108 EurotestPV tester can perform all the necessary tests, such as insulation resistance current, voltage, power, insulation and continuity, module temperature, and more.
With Eurolink software, you can produce professional reports, which include measuring the performance of different PV modules, inverters, and more.
Metrel PV tester enables electrical installations to be completely tested according to EN 61557, as well as to carry out all the required tests for 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 as required by EN 61829 and power measurements on Inverter’s DC and AC sides.
MI 3108 EurotestPV is designed for working under demanding conditions (up to 1000 V, 15A DC). In order to enhance user safety, the MI 3108 EurotestPV comes with a PV Safety Probe that ensures safe disconnection every time.
Key features
Photovoltaic installations:
- Calculation of STC values: the measured current and voltage values are, according to environment conditions, recalculated to Standard Test Condition values which makes possible, to compare the results even if they were taken under different test conditions.
- Graphical representation: the I-V characteristic of PV module or string is graphically represented on LCD display.
- Power and efficiency measurements: 2 voltage & 2 current channels for simultaneous AC & DC parameters measurements.
- PV Remote Unit: Optional unit for simultaneous measurements of solar irradiation and temperature of PV module.
Electrical installations:
- RCD Auto: Automated RCD testing procedure significantly reduces test time.
- Trip Lock function: Loop impedance test are performed without tripping the RCD.
