Metrel MI 3109 EurotestPV Solar PV Tester
This photovoltaic (PV) tester performs all necessary tests required for photovoltaic installations.
MI 3109 carries out the tests required by EN 62446, plus 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).
MI 3109 EurotestPV Lite is optimised 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.
The Metrel MI 3109 is perfect for first inspection of PV systems as well as periodic maintenance tests and evaluation tests or troubleshooting tests.
Metrel MI 3109 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
