Metrel MI3108ST Eurotest Solar PV Tester
Includes: MI 3108 Eurotest PV, Soft carrying bag, Tip commander, Test lead, 3 x 1.5 m, Test probe x3, Crocodile clip x3, PV Safety Probe, PV MC3/4 male/female adapters, AC/DC current clamp, PV reference cell + cable adapter, Temperature probe + cable adapter, Power supply adapter + 6 NiMH AA batteries, USB and RS232 - PS/2 cable, PC SW EuroLink PRO, Carrying straps, Instruction manual and handbook on CD, Calibration certificate.
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.
