Metrel MI 3114 PV Analyser
- A tester perfect for photovoltaic (PV) and electrical installation testing
The Metrel MI 3114 PV Analyser is a powerful tool for testing photovoltaic (PV) systems. It can handle a maximum voltage of 1500 V and a short circuit current of 40 A.
The analyser supports IEC 62446-1 compliance and covers all Category 1 tests, including insulation resistance of PV strings, Isc and Uoc measurements, and STC value calculations. Real-time irradiation and cell temperature readings are obtained via a wireless remote unit. All Category 1 tests are executed with a single touch using the auto test function.
The Metrel MI 3114 PV Analyser features a large colour touch-screen for intuitive operation, allowing users to set up tests, store results, and review data. Incorrectly entered parameters can be corrected even after execution.

Metrel MI 3114 Measuring Functions:
- 1500 V insulation resistance of PV strings
- Continuity of PE conductors
- Polarity test
- Isc and Uoc test
Metrel MI 3114 Key Features:
- Auto test for Category 1 tests
- STC value calculation and comparison with nominal data
- Correction of previously entered parameters
- Memory organiser with search and PV modules database
- Wireless (Wi-Fi) remote unit for irradiation and temperature measurement
- AUTOSEQUENCE
For advanced data management, the analyser integrates with Metrel ES Manager PC software, enabling:
- PC SW Metrel ES Manager to prepare measurement structure and measurements in advance, upload or download that structure and then reviews the results, PV modules DB explorer and as final act, the generation of professional report.
Metrel MI 3114 Applications:
- Testing of large 1500 V PV plants
- First inspection testing
- Periodic and maintenance testing
- Evaluation and troubleshooting
- Professional report generation
