Solar cells & insulation tester
Elma
Solar cells & insulation tester
Art. no.: 4202800
HT PV-Isotest is the perfect instrument if you need to commission and troubleshoot photovoltaic systems up to 1500VDC, which is the standard on many new systems. An ordinary isolation tester only works on the DC circuit at night. As soon as the sun shines on the panels, there is voltage on the circuit and a standard insulation tester gives up. PV-Isotest also works on a string with DC voltage up to 1500V. PV-Isotest can also measure continuity in PE conductors with 200mA. With the unique GFL (Ground fault locator) function, the earth fault location on a string can also be placed. With a memory of 999 measurements and the included software, the results are easily saved and documented on a PC. High safety is ensured when the instrument complies with CAT III 1500VDC / 1000VAC. The instrument is delivered ready for use with test leads, crocodile clips, MC4 to the track, PC cable, software and batteries in a sturdy bag.
Solar cell tester Eurotest MI3109PV
Metrel
Solar cell tester Eurotest MI3109PV
Art. no.: 4203585
The MI3109 Eurotest PV Lite is a solar installation tester for all necessary tests on a solar installation. Everything you need to do Category 1 tests (Equivalent to the commissioning check on solar cells). This includes all tests in accordance with EN 62446, but also covers the measurement of the solar panels I-V characteristic, recalculation to STC values described in EN 61829, and power measurements on the DC and AC side of the inverter (single-phase only).The MI3109 can be used for initial inspection in connection with the commissioning of solar installations, periodic maintenance, evaluation tests or troubleshooting. With the Autotest function, a complete test, necessary for the verification of PV installations in accordance with EN 62446, can be performed with the push of a button.

Test Features:
• continuity test
• insulation test
• open-circuit voltage (Voc)
• short circuit current (Isc)
• solar radiation (requires A1427 PV Reference Cell)
• temperature (requires A1400 PV Temperature Probe)
• DC power and efficiency (requires current clamp, eg A1391)
• I-V characteristic
• AC power and efficiency (requires current clamp, eg A1391)

The MI3109 is supplied ready to use in a case including test leads, test sticks, alligator clips, MC3/4 adapters, AC adapter and batteries, as well as all necessary cables for connection to a PC. Measurement data can be saved in the instrument and processed via the Eurolink PRO PC software (compatible with Metrel ES Manager) and the Eurolink PV android app (requires an A1436 BT dongle).
