Since we are currently receiving an increasing number of inquiries from customers who are having problems registering their balcony power plants with their supplier due to the lack of VDE certifications for the cheaply purchased balcony power plants from eBay and other cheap suppliers, please pay URGENT attention to all the necessary certifications when purchasing your new balcony power plant. The VDE4105 certification is particularly important here. ALL balcony power plants offered by SolX have the necessary certifications for smooth registration and safe operation of the plants.
