FAQ

Who is Weidmüller? With their in-depth expertise, they support you and their partners worldwide by providing products, solutions, and services in the industrial sector for energy, signals, and data.

How do I protect my PV system from lightning strikes? - The surge protection device in the generator connection box (GAK) is an integral part of a building's lightning protection system and has been mandatory since 2019 in accordance with EN 51643-32. This protective mechanism aims to protect your photovoltaic system from surges that may occur near your building.

How can a long service life of the generator connection box be ensured? - To ensure the planned profitability of the photovoltaic system, it is important that all components, from the modules and inverters to the generator connection boxes (GAKs), have a service life of at least 20 years.

What are the special features of PV Next GAKs? A roof-mounted photovoltaic system requires a generator connection box (GAK) that is approved in accordance with IEC 61439-2 regulations and protects the system from overvoltage. The GAK PV Next offers additional functions such as string bundling to reduce cabling costs. Depending on the inverter of your photovoltaic system, a corresponding variant of the GAK is required.
