The Metrel MI 3109 EurotestPV Lite is a photovoltaic (PV) tester. It performs all necessary tests required on photovoltaic installations.

This device is optimized for PV tests and therefore the Autotest operation mode is implemented which is intended to perform a complete set of test needed for verification of PV installations according to EN 62446 with the press of a single button.

Measuring Functions:

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

Electrical Installations:

• Insulation resistance
