PHOTOVOLTAIC AND ELECTRICAL INSTALLATION TESTERSMI 3108 EurotestPV and MI 3109 EurotestPV LiteMI 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 photovoltaic (PV) installations. This includes all of the tests as required by EN 62446, but also includes I - U characteristic, Calculation of STC values 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.

MI 3109 EurotestPV Lite is optimized for PV tests only. The Auto function is intended to perform a complete set of test needed for verification of PV installations according to EN 62446. With optional accessories the same PV test functionality as with MI 3108 EurotestPV is available.

MEASURING FUNCTIONS Photovoltaic installations:Measurements on DC side of PV instal-lation:• 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 (power quality):• Voltage, current, frequency, power, PF,

energy, harmonics;• Efficiency of PV module, inverter, PV

system calculation.

Electrical installations (MI 3108 only):• Insulation resistance*;• Continuity of PE conductors*;• Line impedance;• Loop impedance (sub-functions with

high current and without RCD tripping);• RCD testing (type AC, A and B);• Earth resistance;• AC current (load and leakage);• TRMS voltage, frequency, phase sequence;• Power, energy, harmonics.* Valid also for MI 3109

KEY FEATURES Photovoltaic installations:• Automatic test procedure according to

EN 62446 (MI 3109 only);• Calculation of STC values;• Efficiency calculations;• Graphical representation of module’s

I - U curve;• 2 voltage & 2 current channels for

simultaneous AC & DC parameters measurements;

• Optional 3-phase measurements in com-bination with Metrel’s PQA instruments.

• Optional PV Remote Unit for simultaneous measurements of solar ir-radiation and temperature of PV module.

Electrical installations (MI 3108 only):• Automated RCD testing procedure;• Support for B type RCD;• Earth resistance measurement;• Built-in fuse tables for automatic evalua-

tion of the line / loop impedance results;• Online monitoring of all 3 voltages;• Scope function;• Loop impedance test without tripping

the RCD;• 1-phase power and energy measurements
