1500 V Photovoltaic systems with style test. The MI 3115 PV analyzer offers tests in accordance with the standard IEC 62446 / VDE 0126-23 and supports all tests and measurements of category 1 and 2. This includes measuring the insulation resistance of the PV strings, measuring the I/U characteristic curve, converting the measurement results into STC values and comparing them with the nominal values issued by the PV module manufacturers. Treatment and cell temperature are measured in real time using the wireless remote unit. In addition, the Category 1 tests can be recorded in an Auto-Test, which allows the user to carry out all desired tests with a single touch of the Start button. Correcting previously incorrectly entered parameters to measurements already performed or groups of measurements. The unit is controlled by a large color touchscreen display that allows the user to work out and start the selected test or measurement, and to save and verify results in numeric and graphical form. Memory Organizer, actions on individual or group measurements, search function. PC SW Metrel ES MANAGER enables the preparation of a measurement structure and measurements, downloads this structure up or down and checks the results, enables advanced analysis of the I/U curve, the DB Explorer of PV modules and the creation of a professional test report.This text is machine translated.
