Defect junction boxes: solutions for installers

Together we enhance safety for your end customer:

Neue Lösung SF ENHave you set up a large number of PV installations in recent years and have now been informed by Solar-Fabrik AG about a risk of fire to the junction boxes?

The certified socket cover, developed in accordance with the highest quality standards by KOSTAL Industrie Electric GmbH, is substituted for the faulty cover right on site by the experts from ADLER Solar and Europe Solar Concept. The allotment of these junction box covers is limited, since they are being produced exclusively for this replacement action.

Ideally, it is no longer necessary to dismantle the modules. The repair can be performed right on site, thus eliminating transport risk and packing costs. In other case, working together with you, we will come up with a concept in which you function as the installer responsible for dismantling and reassembling the photovoltaic modules and ADLER Solar repairs them. Depending on the possibilities on site, the repair can be performed right in your region. Each repair is subsequently verified by a functional test.

Thanks to the quick solution, your customer also avoids losses in earnings, and safety is soon restored.

Profit from our experience:

ADLER Solar specializes in repair solutions for junction boxes. In the past seven years, we have worked on more than 300,000 PV modules with problem junction boxes. The repair procedures have been performed and further developed in collaborative partnership with the manufacturers of the modules.

„We are glad to be able to offer an optimized solution in the interest of our customers. With this solution, we would like to get the cause of the problem under control and thus provide long-term safety and optimum installation performance.“
Gerhard Cunze, Managing partner ADLER Solar

 

Which PV modules are affected?

According to information from Solar-Fabrik AG, these are products with the designation Premium L, M, XM and S. The junction box has only one connecting cable and an LC-4 plug. We will be glad to help you identify them.

A typical repair could run as follows:

  • Using a checklist, we inquire about the outline data, such as serial numbers, number of installations and modules affected, locations and local conditions
  • We agree on a joint solution concept at short notice and set a date for the work after hearing from your end customers
  • The modules are dismantled only if necessary at the agreed repair frequency
  • Repair work is performed
  • A possible reassembly and commissioning
