Frame mounted ts4 rail contact
I have some panels that will be short side vertical mounted on rails. When test fitting the ts4-a-o to the frames, I notice that they hang just below the frame edge when tipped over such that a straight edge moved along the frame will contact the module underside as it sweeps over the module on my REC panels. With the mounting orientation, the ts4 will overlap with the rails.
Is there any concern with the ts4 body touching the rails (heat issues would be my main thought but I suppose that is likely to be a heat sink and not adding heat)? It is preferred to rail mount the ts4 if the would otherwise contact the rails?

Hi David, thank you for this question. Our TS4 mounting instructions call out module clearances but nothing about touching the frame. At no point should the TS4 touch the module since that will cause hotspots. The silver clips on the top of the TS4 can be removed, and the device can be directly bolted to the frame, so there shouldn't be an issue.

I don't think I was clear - the clearance I am asking about is not between the frame of the PV module and the optimizer, but between the optimizer and the support rails of the roof mounting structure below the PV module (in this case a set of IronRidge XR10 (https://www.ironridge.com/component/xr-rails/). It looks like the optimizer on its lower end will hang down just even with the PV module frame when clipped on, and since the PV module frame is clamped to the rails, when in short side vertical orientation (or long side sideways) the bottom of the optimizer appears that it will cross the supporting rail and therefore lay in contact with it. I am guessing that this is not an issue as I expect the installation manual would have called it out if it was but I wanted to confirm.
I could also upload a drawing if that would help (and I can reduce the quality to make it fit under the 2mb limit).
