Unfortunately, we do not stock pre-assembled cables in various lengths. We are therefore unable to offer a cable as a spare part.
However, you can obtain a two-core cable with 1.0 mm² from a DIY store, for example, and insert this cable between the solar module and the plug (connection with screw or plug-in terminals). In this way, the plug of the cable from the solar module is retained.
The cable should not be extended too long, otherwise the voltage may drop and the light output may be reduced.
Note: Converting the product invalidates the guarantee and warranty. The conversion should be carried out by a qualified electrician. We accept no liability for incorrect conversion.
