Positive: Good accessibility. Quick and useful answers to technical queries. Clear website. Good quality and good packaging of the components used.
Negative on the Balkony: The sliding nuts on the Balkony should have bent up corners or a spring band on all 4 corners. The aim is that the sliding nuts hook in the mounting groove and not align again longitudinally to the mounting groove when tightening, or slip completely out of it.
P.S. There are such sliding nuts.
The lower module clamp on the Balkony is open at the bottom.
If this lower module clamp is/is not properly tightened, the module could slip down out of the mount.
It would be nice if the spring, summer, fall and winter elevation to the sun was not only possible in the fixed steps, but variable. This could be realized by two parallel running aluminum rails, each with a longitudinal groove, which can be pushed further apart or more together and then fixed with a wing screw variable. This could then be offered as an optional accessory.
The dummy plug of the inverter must always be included in the accessory pack for the inverter and not be included in other places.
I had ordered a set of 600 watts for flat roof installation.
The delivery was fast, but the Panells were poorly packaged.
(A few more adhesive strips would have helped).
The set was cpl. suitable for assembly and complete, so I could start immediately.
The instructions were good.
I would buy it again.
The written contact about an inquiry was answered quickly and to my satisfaction.
The processing of the purchase was problem-free. The delivery by the shipping company was already 1 day after the shipping information. The installation instructions are exemplary, the system is easy to install on a flat roof and has already been working for 1 week to my complete satisfaction.
Unfortunately, the Schuko connection cable of my system was defective, which is why it did not work after installation. Soon, after consultation with the service, I sent the inverter for testing. It came back a few days later with a test report and was OK. The Schuko cable was the cause. Now the plant is running. The technical service has always responded quickly and answered. It would have been nice to have a proactive support from Yuma, after it was clear that the inverter is ok. But now the system is running and it is good. I will also recommend Yuma to others.
Order went well in the context of the current situation. Payment and delivery flawless. The plant is built at my place and pleases me with electricity production in your possibilities. The price for such a plant is of course outrageous. But the political and economic situation promotes such a thing.
I am satisfied. Keep up the good work Yumateam.
The user should definitely order a current/power meter. Preferably the one from Fritz!DECT210, but at least a current/power meter from the DIY store. Since this is not possible with Wieland energy box, one should provide this in the house system behind it. Otherwise you can only speculate about function and yield.
Payment processing with the payment service provider turned out to be complicated. The commissioned bank did not execute the payment for security reasons. The angle of the panels cannot be changed. An angle of 20 degrees is fine in the summer when the sun is high, but in the darker season 30 - 40 degrees would make more sense. A suitably variable frame can not be a technical problem.
Easy assembly, All documents, descriptions and registrations available.
Super simple and fast.
Plant works great. We are highly satisfied and make our own small contribution to renewable energy. NEIGHBORHOOD!
The technical information and the installation instructions as well as the complete delivery has convinced me. I have shown my installed plant known All were convinced of their plant and processing.
With kind regards Horst Meyer
