Metrel MI3108ST Eurotest Solar PV Tester

The Metrel MI 3108 EurotestPV is a combined photovoltaic tester and electrical installations safety tester. It enables complete testing of electrical installations according to EN 61557 standards and in addition performs all necessary tests required on single-phase photovoltaic (PV) installations. This includes all of the tests as required by EN 62446, but also includes I - U characteristic, Calculation of STC values as required by EN 61829 and power measurements on Inverter’s DC and AC sides. The unit is designed for the demanding working conditions (up to 1000 V, with 15 A DC). To greatly improve user safety the MI 3108 EurotestPV comes with the PV Safety Probe which ensures safe disconnection every time. MEASURING FUNCTIONS Photovoltaic installations. Measurements on DC side of PV installation. Voltage, current, power. Uoc (Open Circuit Voltage) and Isc (Short Circuit Current). I - U curve of PV modules and strings. Irradiance. Module temperature. Measurements on AC side of PV installation. Voltage, current, power. Efficiency of PV module, inverter, PV system calculation.
