Seal underground drilling

Since I have mentioned several times, also in writing, to the photovoltaic provider how important the topic of proper house entry is to me, I will insist on rectification here. However, I am not sure how such a thing is properly executed according to the current state of the art. How should it have been done better?

About the free space in the multi-utility duct. There is usually always 1 out of 4 free.

Unfortunately, there are none. Energy suppliers and telecom have made their own house entries with their own components.

Ring seal from Doyma e.g. would be the right one.

Here are some pictures. On the left, house entry from the energy provider and on the right from the photovoltaic system.

I am not an expert, but as a client I would not accept that. Take a look for example at uga.eu, they have the type FHE Flexible Hauseinführung, that looks suitable to me. In case of doubt, I would get an expert/ construction supervisor. Any damage and trouble later on is more expensive...

I have also pointed out several times that this issue is important and that the house entry is carried out according to the current state of technology. A bit of silicone around it seems to me to be the wrong solution....
