4.0 out of 5 stars Works and is (mostly) easy to set up
Reviewed in the United States on June 27, 2023
The actual solar panel was easy to set up and use, although, the wire from the solar panel you connect to the controller could be a bit longer. That, however, could be just a personal issue for the project I used it for. The charge controller works nicely, but I have no idea how to use it or what its functions are. The manual it came with for the charge controller is completely in German, and trying to google translate everything just doesn’t work. The box for the controller and the solar panel manual itself are both in English. Needless to say, just kind of confused why the operation manual for the charge controller is only in German. Other than that, nice build and easy to use.
