First, a rough overview of the volume of my order to Enerix Oberfranken. The order, which was signed at the end of August 2022 and completed in April 2023, included the design, delivery, installation and commissioning of a PV system with battery storage (Fenecon Home), inverter (Fenecon Home) and 31 solar modules of Qcells 410Wp (12 on the garage roof and 19 on the house roof) as well as a completely new house distribution system with all circuit breakers, FI switches, etc. and an automatic consumer switchover AVU from Fenecon. So a turnkey system, except for earthworks in the outdoor area, without personal contribution by me.
Unfortunately, I cannot give this company a good rating. In the familiar format of five stars, I can unfortunately only give a maximum of one star.
The negative evaluation refers on the one hand to Enerix Oberfranken as contractor itself, and on the other hand to the company Modern Ishtar subcontracted by Enerix Oberfranken, which carried out all the work in, on and on our house, from installation to commissioning.
It started already in November 2022 with the fact that contrary to all agreements, the solar modules were not stored by Enerix itself until the start of installation, but suddenly the shipping company stood without notice in front of the front door. I made my garage available as a storage location, but then I could no longer use it myself for my car until the start of installation, which was at the end of January 2023.
Now to the company Modern Ishtar subcontracted by Enerix Oberfranken.
I would like to list just a few points that lead to this poor rating:
- crooked components (inverters, cable ducts, surge arresters, new house sub-distribution).
- Life-threatening electrical installation. These include:
- open cable extensions by means of terminals. Junction boxes were only installed after I had criticized the work and referred to the valid standards of DIN VDE.
- Solar power cables lying flat on the roof tiles. They were neither tied up nor mostly not provided with a protective sheathing to protect them from UV influences. This was also only carried out due to my complaint based on DIN VDE 100-712.
- The yellow/green equipotential bonding cable of the house roof unit was simply attached to the remains of the lightning conductor, which had been taken out of service years ago, and the cable from the garage unit was then correctly attached to the common equipotential bonding rail of the house itself.
- Loosely laid 400V cable (5x16 mm2) without strain relief.
I could enumerate some more things concerning the deficient electrotechnical installation, but I want to limit myself here.
Actually, such elementary things should be known to an electrician and the work should be carried out accordingly. It cannot be demanded of every customer that he himself has expertise in this subject and can point out defects. A layman would have lost hopelessly in this case and would probably have to live with a life-threatening installation. It was completely incomprehensible to me that Enerix Oberfranken, namely Mr. Buchmann, was always fully behind this company subcontracted by him and its poor quality of work.
I can only warn against this unprofessional work carried out by the company Modern Ishtar from Ansbach, which of course in consequence also throws an extremely bad light on the main contractor Enerix Oberfranken.
I could leave out annoying side effects, but I would like to mention them anyway.
These included the fact that the construction site was left neither tidied up nor cleaned after work, which was often not until around 6:30 to 7:00 pm. Tools and materials were simply left lying around somewhere, whether outside or inside, just where they were last used. Only after being asked to do so did they pick up a broom to clean up the leftovers.
I also very often had to help out with household ladders and even tools and materials. Each individual item by itself seems negligible in its mention. The sum of such occurrences, however, is grueling and incomprehensible. A so-called "specialized company" has everything with it and does not have to ask for it in order to be able to do its work.
There would be other points to list, but I would like to limit myself to what has been written about the company Modern Ishtar.
As far as Enerix Oberfranken is concerned, I can say that not everything went according to plan here either. From the already mentioned unannounced delivery of materials, to unjustified demands for money that deviated from the contractual payment schedule, to non-binding appointments, because there was no access to Modern Ishtar, to no reaction when it came to more unpleasant issues such as "why is the plant not registered with the power company, although it is put into operation?
All these experiences strengthen me in the decision, Enerix Upper Franconia in no case to recommend, even to warn against this company, at least as far as the manual work is concerned.
I will not place any more orders with this company.
