The Mobile EL 02 is a portable PV module tester. The Mobile EL 02 can carry out testing directly at the module installation or storage site. It is not necessary to remove the modules from their mounting structures when using the tester.

With the appropriate configuration, it can also carry out tests on uninstalled modules before they are activated.

With the Mobile EL 02 high-resolution portable device is used to carry out:

• • electroluminescence testing to detect possible problems such as microcracks or PID in the module cells
  • diode testing

The test is carried out without removing the modules from their mounting structures, in low sunlight conditions..

Alternatively, in the case of quality control of new, uninstalled modules, the test can be performed in a roofed area..

The Mobile EL 02 can test up to 400 modules every 8 hours.A test certificate is issued for each tested module which includes the full results of the electroluminescence test and labelling of cell defects.
