The supplier was inflexible, that's why the devaluation. Why at a distance of the warehouse of approx.
5 Km a delivery time window of 5 hours is necessary and on the day of delivery no more detailed information
could be given was not comprehensible.

The system is expensive, but everything is transparent and complete.

Thank you for the delivery

I bought the balcony power plant YUMA Front on recommendation and am very satisfied with the high quality components, which were delivered perfectly packaged by freight forwarding . The information on the website is very good. Ordering, payment and delivery were uncomplicated. The simple assembly described in the handout is not so simple, just because the pictures in it are not really strong statement. Larger slotted holes in the frame would be helpful. But with patience and spit you get that with a few friends already bin. Clear purchase recommendation !

The service for telephone queries is good. The enclosed installation instructions are clear and well structured. However, as a layman, two mounting points for on-roof installation on sheet metal or bitumen roofs were not quite clear to me. Once they write in the instructions the edge distance should be 15 cm. Measured from where? Here a specification in the corresponding sketch would be helpful. Then, when mounting the inverter, there should be an indication whether the inverter should be mounted on or under the top-hat rail. If mounted on the rail, the screws are too high in my opinion and could damage the solar modules. It would also be advisable to specify a minimum distance between the roof and the solar module. With the inverter, it would be very welcome if in the future the LED display was attached so that it could be seen even when mounted. Also, a tidier arrangement could be chosen for the cable tangle under the modules. However, this only concerns the optics and not the functionality.
The specification of the operation with Schuko plug is very general and unfortunately not yet conclusively regulated by law.
All in all, we are proud owners of a balcony system and hope we can make a small contribution to the energy transition.

Very fast delivery (within a week). Unfortunately, a holder set was delivered incorrectly, but was exchanged very quickly and unbüroratisch. Unfortunately, the network operator make the TWS Netz GmbH problems and insists on an energy socket according to current DIN VDE V 0628-1 for registration and does not accept a Schuko plug. Therefore, my advice before ordering the plug with the network operator clarify.

Ordered and delivered super fast. Today mounted on the roof. Everything no problem with the complete set.
2 hours of work - Everything worked immediately and I am happy about my 600W in the peak.
Registration was also easy through the forms.
Next time I would order 2 double packs, but that is not allowed to do anything officially in Germany.

Fast delivery,
good instructions and information for assembly,
material and accessories to the last detail,
great, easily accessible customer service.
The only point that I did not find so good was the unannounced delivery by the shipping company.
Nevertheless, a clear recommendation.

I was thrilled with the fast uncomplicated delivery. A great complete package.
Of course I have recommended you immediately, with success.
The WiFiSwitch plug I have seen cheaper elsewhere. But since with you the service is convincing, everything is there, just the complete package, I think that's not bad. Quality has its price. Thank you very much.
