I had the 9 panels and my wifi module was not working. So I decided to purchase a new wifi module and it worked perfectly. It was a bit pricey, but I guess you gotta do what you gotta do for such a premium product.
Really fits optically to the light panels
This not a casual power brick, it's the heart of those light panels. You can connect up to 30 panels onto just one power brick. The temperature level is really good. I used 21 panels on one brick for about 8 hours on max brightness and it was only warm. The best thing ist, that the cable is soo Long. I think it's about 4m and has a power and a button to select the different modes.
First one failed which was a tad disappointing however they sent me a new one and we were back up and running in a few days. No complaints new one works without issues.
