In this video I will explain the example structure of a PV generator junction box (GAK) and show the system components (2-wire isolating terminals, fuse base, PV fuses, surge protection and equipotential bonding). The surge protection should be installed as far towards the generator as possible, so we recommend mounting it e.g. B. directly under the roof (also note a service access, alternatively the GAK can also be installed in the house connection room, for example. The structure of the GAK can of course also look different, depending on the overall situation of the PV system and what is the best technical and structural fit. ! Attention: Pay attention to the nominal voltages of the components depending on the project! I expressly point out that work on electrical systems may only be carried out by qualified electricians, as required by law. I accept no liability for the technical, legal and safety-related accuracy of the content in this video.
