[RE-wrenches] High altitude off-grid systems

[Ray]

We've had some systems at 11,000 ft plus, for almost 20 years. We have 
mixtures of Outback, Midnite, Blue Sky, and old Trace equipment.  Never 
any issues with electronics related to altitude.  Actually the altitude 
related system issues are generator derating, and array output exceeding 
STC ratings on really clear cold days due to the thin atmosphere.  The 
third issue would be installers not being able to catch our breath after 
jogging back to the truck.
