I’ve got a 600kw project in the design phase, the roof is a 1 degree slope flat roof with a standing seam material that has 2” high seams every 40” on center.
I would really like to avoid rapid shutdown; however, all of the UL 3741 solutions out there are only for TPO and built up roofs (PanelClaw, Unirac, IronRidge, Sollega). PanelClaw would likely work since the seams are north south and the east west rails clear the 2” seam; however, they say it’s incompatible.
We were looking at MetalX railless; but that isn’t UL 3741 either.
I’d do just about anything to avoid 1200 rapid shutdown MLPE’s on this job.
Anyone know of a compatible product?
