Photovoltaic and electrical installation tester Test 1500 V photovoltaic systems in style. The Ml 3115 PV Analyser offers testing in accordance with the IEC 62446 standard and supports all categoryl and category 2 tests and measurements. Like insulation resistance measurements of PV strings, l/U characteristic measurements, and the conversion of measured values to STC values and comparison with nominal values given by the PV modules manufacturers. The irradiation and cell temperature are measured in real time with the wireless remote unit. Additionally, categoryl tests are collected in one auto test, which enables the user to perform all the desired tests with a single touch of the start button. MEASURING FUNCTIONS • 1500 V insulation resistance of strings; • Continuity of PE conductors; • Polarity test; • Isc and Uoc test; • I/U characteristics; • Wireless acquisition of irradiation and temperature of PV modules. KEY FEATURES • Insulation and I/U measurement of 1500 V PV systems in one instrument. • Capacitive measurement method. • Wireless (Wi-Fi) remote unit for measuring and logging of irradiation and cell temperature of PV modules. • Auto test for Category1 tests. • Calculation of STC values and comparison with nominal data. • Correction of previously wrong entered parameters on already executed measurement or group of measurements. • The instrument is controlled via a large colour touch screen display from which the user can prepare and start the selected test or measurement, store results, and review them in numerical and graphical form. • Memory organizer, operations on single or group of measurements, search functionality. • PV modules database handler. • AUTOSEQUENCE. • PC SW Metrel ES Manager enables prepreparation of measurement structure and measurements, upload or download that structure and then reviews the results, enables advanced analysis of the I/U curve, PV modules DB explorer and generation of professional report. APPLICATION • Testing of big 1500 V PV plants • First inspection testing • Periodic testing • Maintenance testing • Evaluation and troubleshooting • Report generation
