It is my current understanding that some manufacturers of metal roofing
will not warranty their products if clamps are used on the standing
seams. The reason given is that clamping the seams prevents the normal
movement of the roofing during expansion and contraction. I can't say
which company it is, but it's a big one.<br>

supports a higher input voltage than 150 V? We would like 175 V.

Hi Peter,

Apollo makes a high voltage 200VOC unit, 80 amps.

And the Classic from Midnight is almost ready to come out if I hear it  
right.

That will be the MidNite Classic, Peter. They aren't quite ready for 
production yet, but thaere are promising Beta units in the field. 200 
VDC I understand.
