Measurements on DC side of PV installation
Insulation resistance
Continuity of PE conductors
Uoc (Open Circuit Voltage) and Isc (Short Circuit Current)
I - U curve of PV modules and strings
Voltage, current and power of strings and inverters
Irradiance
Module temperature
Measurements on AC side of PV installation
Voltage, current, power
Efficiency of PV module, inverter, PV system calculation
Insulation and I-U curve measurements in one instrument: with MI 3109 only one instrument is needed to perform insulation measurements with up to 1000V for proofing the PV installation safety and I-U curve measurements needed for evaluation and troubleshooting of PV modules or strings
Autotest: This function is intended to perform a complete set of tests according to EN 62446 on PV modules or strings with pressing only one button
insulation resistance between positive output and earth
insulation resistance between negative output and earth
open circuit voltage
short circuit current
Calculation to STC values: the measured current and voltage values are, according to environment conditions, recalculated to Standard Test Condition values which makes possible to compare the results of different measurements even if they were taken under different test conditions
Efficiency calculations: 2 voltage & 2 current channels for simultaneous AC & DC parameters measurements
PV Remote Unit: Optional unit for simultaneous measurements of solar irradiation and temperature of PV module
Graphical representation of module’s I - U curve: the I-V characteristic of PV module or string is graphically represented on LCD display
Memory: Up to 1800 test results or up to 500 graphical results with timestamp can be stored in internal memory
BT connectivity: it enables BT communication with Android tablets and smart phones via optional BT dongle
Android application: enables advanced data management APP EuroLink PV
PC SW EuroLink PRO enables downloading, uploading, review, analyses and printing of test results
