[RE-wrenches] wire management on Qcell AC module

[Jay]

These modules are designed for  racking w/o MLPE and the rest of the world that doesn’t use MLPE. 

And code in both 300.11 and 330 ish say that wires need to be supported between 6” and 12” ( I’m not sure which is the correct one to use, I’ve always been told to use 12”) from any box or termination. Which means to me that wire extensions are required. 
Adapters might be needed anyway If the modules and MLPE don’t have same ends to meet both OEM, UL, and NEC requirements. 



Just the way it is, but boy did I wish they made those Junction boxes with wire mounting clips on them so we could easily go across the module in the middle and be supported.

The module is the half cut cell type with the DC leads coming from either side of the middle of the module. The modules come with the wires taped to the back of the module. If you remove that tape, there appears to be almost no way to properly manage those wires. Is that tape meant to just keep the wire on the back of the module forever? Would that even last more than a year? I am curious what other people have done for these if they have used them or something similar. Maybe if you get the rail in the right spot, the wires will just sit on the rail...
