Metrel's new product: MI 3116 PV Analyser XA

As 1500 V photovoltaic installations with high-efficiency and bifacial modules become more prevalent, the necessity for electrical safety testing grows, which is why Metrel created an advanced multifunctional electrical safety tester tailored for these installations.

The MI 3116 PV Analyser XA, which supports testing of high-efficiency and bifacial modules and PV strings in parallel with a 40 A current (50 % faster testing). Additionally, it offers testing in accordance with the IEC 62446 standard and supports all category 1 and category 2 tests and measurements. This includes insulation resistance measurements of PV strings, I/U characteristic measurements, and the conversion of measured values to STC values and comparison with nominal values given by the PV modules manufacturers.

The MI 3116 PV Analyser XA is an advanced photovoltaic and electrical installation tester designed for maximum efficiency and precision. It combines insulation and I/U measurements of 1500 V PV systems in a single device while ensuring accurate testing of high-efficiency PV modules. A wireless (Wi-Fi) remote unit enables real-time measurement and logging of irradiation and cell temperature, enhancing data collection. The Auto Test function for Category 1 tests streamlines operation, while the innovative correction feature allows users to adjust previously incorrect parameters on completed measurements or entire test groups, ensuring greater accuracy and reliability in PV system diagnostics.
