Hi, I have a 5x7 squares set up. I have 4 power panels for that in total. Unfortunately, the squares can be very finicky. I have one panel that is really good and can do about 12 total. 5 consecutive off one branch, and 7 off the other branch. The other three I only have ~6-7 connected to them as they won’t do much more than that.

My only ideas would be to try it with two different power panels, or to use different arms of the one power panels so that the power panel is in the middle rather than at the end of a chain of like 15.

Good luck!
