Photovoltaic and electrical installation tester The MI 3116 PV AnalyserXA 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. MEASURING FUNCTIONS • Maximum system voltage up to 1500 VDC; • Maximum harness Sub Array current up to • 1500 V insulation resistance of strings; • Support for bifacial modules; • Polarity test; • Acquisition of irradiation and PV module temperature. • Measurement of high efficiency PV modules. • Capacitive measurement method. • Wireless (Wi-Fi) remote unit for measuring and logging irradiation and cell temperature of PV modules. • Auto test for Category 1 tests. • Calculation of STC values and comparison with nominal data. • Correction of previously incorrectly entered parameters on already executed measurement or a group of measurements. • The instrument is controlled via a colour touch screen display through which the user can prepare and start the selected test or measurement, store results, and review them in a numerical and graphical form. • Memory organizer, operations on a single or a group of measurements, search functionality. • PV modules database handler. • The SW 1201 Metrel Electrical Safety Manager (MESM) is a powerful software solution designed to streamline electrical safety testing. It allows users to predefine measurement structures, upload or download test data, and efficiently review results. With advanced features such as I/U curve analysis, a PV module database explorer, and professional report generation, MESM enhances workflow efficiency and ensures precise data management. • Testing of large 1500 V PV plants • First inspection testing • Periodic testing • Maintenance testing • Report generation Electromagnetic compatibility
