 The MI 3109 EurotestPV Lite is a high-quality photovoltaic tester that can perform all the necessary tests, such as current, voltage, power, insulation and continuity, insulation resistance, module temperature, and more.
A series of professional reports based on the Eurolink software included measure the performance of different PV modules, inverters, and more.
This includes all of the tests as required by EN 62446, but also includes I – U characteristic measurements, calculation of STC values as required by EN 61829 and power measurements on Inverter’s DC and AC sides (single-phase only).
Metrel PV string tester is optimized for PV tests therefore the Autotest operation mode is implemented which is intended to perform a complete set of test needed for verification of PV installations according to EN 62446 with pressing off only one button.
With Metrel solar PV instrument, the tests for the first inspection of PV systems as well as periodic maintenance tests, evaluation tests or troubleshooting tests are possible. With optional accessories the same PV test functionality as with MI 3108 EurotestPV is available.
Key features
- Insulation and I-U curve measurements in one instrument: with MI 3109 only one instrument is needed to perform insulation measurements with up to 1000V for proofing the PV installation safety and I-U curve measurements needed for evaluation and troubleshooting of PV modules or strings.
- Autotest: This function is intended to perform a complete set of tests according to EN 62446 on PV modules or strings with pressing only one button:
- insulation resistance between positive output and earth;
- insulation resistance between negative output and earth;
- open circuit voltage;
- short circuit current.
- Calculation to 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 of different measurements even if they were taken under different test conditions.
- Efficiency calculations: 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.
- Graphical representation of module’s I – U curve: the I-V characteristic of PV module or string is graphically represented on LCD display.
- Memory: Up to 1800 test results or up to 500 graphical results with timestamp can be stored in internal memory.
- BT connectivity: it enables BT communication with Android tablets and smart phones via optional BT dongle.
- Android application: enables advanced data management APP EuroLink PV.
- PC SW EuroLink PRO enables downloading, uploading, review, analyses and printing of test results.
