I picked up the plant myself, which was feasible without any problems. All components were present and of the best quality. It is very advantageous to receive a complete plant with all the individual parts without having to assemble and procure them individually.
The installation of the tile roof beams is a bit of a challenge at first because of the 0.5 - 1 cm gap to the roof panel below. Also, to pre-drill for the huge screws still had to get a special long wood drill and for relining appropriate wood. From the second hook, this then already goes briskly, also the necessary Abflexen of the tile plates. The presence of a drill, cordless screwdriver and flex are, of course, a prerequisite. Who does not install on the roof, has of course here less problems and work, but perhaps also less yield.
Since in the beginning the data logger passed on its values via W-Lan, but always (correctly) reported only 0 watts yield, a troubleshooting resulted. Here the friendly and competent exchange with Mr. Krause was very helpful. Finally, a defective contact of the properly plugged together cables of the converter and the connection at the socket was found. After this was rewired, the PV system started up without complaint and has been doing its job ever since.
All in all, a very successful and good investment, for which I can fully recommend the company SonnStrom.
