Metrel MI3109 EurotestPV Lite Solar PV Tester and I-V Curve Tracer - PRO Kit

Metrel MI3109 EurotestPV Lite Solar PV Tester and I-V Curve Tracer - PRO Kit is a versatile photovoltaic multifunction tester (MFT), providng all required tests for PV Installations.

The focus of the EurotestPV Lite is on PV testing and this is demonstrated by its Autotest one-button setting, providing a complete set of tests needed for certification of PV installations according to EN62446 at the push of a single button.

The MI3109 has a variety of capabilities, providing voltage, current and power measurements on both sides of a PV installation, as well as installation resistance on electrical installations and the continuity of PE conductors.

The MI3109 also performs I-U characteristic measurements, single-phase power measurements on both Inverter sides (AC and DC) and calculation to STC values, in addition to efficiency calculations, making it the ideal tool for photovoltaic engineers.

Metrel EuroLink PRO software

To aid accessibility even further, the MI3109 comes complete with Metrel’s EuroLink PRO software, perfect for creating Visual Inspection Reports and Testing Result Reports.

Metrel A1378 EurotestPV Remote

The included Metrel A1378 allows for simultaneously measurements of solar irradiation and temperature of PV module. The unit comes with a backlight LCD display, offering users the ability to read results, Indications, measurement parameters and messages easily.

The Metrel MI3109 EurotestPV Lite Solar PV Tester and I-V Curve Tracer - PRO Kit comes packaged with a large assortment of practical accessories. The Pro Kit comes complete with the contents of the standard set, meaning you also receive a range of Universal PV and PV Continuity test leads, test probes, crocodile clips and PV MC3/4 male/female adapters, plus a carrying strap and soft carry case to look after the instruments in the field. The PRO kit also includes as well as both a PV Safety Probe A 1384 and Temperature Probes
