In today's world, network technology has become an integral part of many home installations. However, this area, in particular, poses a significant risk of errors during the commissioning of modern systems. Even my-PV devices like the AC ELWA 2 or the AC•THOR 9s are typically connected to the network with the signal source. Unfortunately, sometimes unknown passwords, firewalls, or other issues can hinder the installation process. This unnecessarily costs time! As the manufacturer of such products, we always recommend our customers to have their own network router on the construction site. There are no special requirements for such routers. Often, a simple device from the discount store could avoid many delays at your construction site.
