The MI 3114 PV Tester is a powerful instrument for testing photovoltaic (PV) systems with a maximum system voltage of up to 1500 V and a maximum short circuit current of 40 A. It supports testing in compliance with the IEC 62446-1 standard and supports all measurement procedures, which cover all category 1 tests. This includes PV-specific measurements like insulation resistance measurement of PV strings, Isc and Uoc measurements, as well as the calculation of measured results to STC values and comparison with nominal values given by the PV module's manufacturer. The irradiation and cell temperature are measured in real time with the wireless remote unit. Additionally, all category 1 tests are collected in a single auto test, which enables the user to execute all the tests with a single touch of the start button. The instrument can be controlled via a large colour touch screen display from which the user can prepare and start selected tests or measurements, store results, and review them. It is also possible to change previously entered wrong parameters on an already executed measurement or a group of measurements.
