Metrel MI 3115 PV Analyser
- A tester perfect for photovoltaic (PV) and electrical installation testing
The Metrel MI 3115 PV Analyser is a powerful tool for testing 1500 V photovoltaic (PV) systems, ensuring compliance with IEC 62446.
The analyser supports all Category 1 and Category 2 tests. This includes insulation resistance of PV strings and I/U characteristic measurements. It also automatically converts values to STC. This makes it easy to compare with manufacturer data.
A wireless remote unit enables real-time measurement of irradiation and cell temperature, while the auto test feature combines all Category 1 tests into a single operation, making testing faster and more efficient.
Metrel MI 3115 Measuring Functions:
- 1500 V insulation resistance testing
- PE conductor continuity testing
- Polarity verification
- Isc and Uoc testing
- I/U characteristic analysis
- Wireless irradiation and temperature measurement
Metrel MI 3115 Key Features:
- All-in-one testing - Insulation and I/U measurement for 1500 V PV systems in a single device
- Advanced measurement technology - Uses a capacitive measurement method for accuracy
- Wireless remote unit - Logs real-time irradiation and temperature via Wi-Fi
- Effortless auto testing - Runs all Category 1 tests with one touch
- STC value calculation - Automatically converts and compares data with manufacturer specifications
