[RE-wrenches] Inverter temp spec for cold regions

[Allan Sindelar]

Wrenches,
Inverter manufacturers have an ambient temperature range with a lowest
temperature spec. For example, SMA has a spec of -13 to +113 degrees F.  In
our area of New Mexico, we have a record cold temperature well below the -13
degrees F. If we mounted the inverter on an outside wall or on a pole, this
would expose the inverter.  
 
I called SMA and asked about this.  They told me that the capacitor blows up
if it goes below the coldest temperature. 
 
My question is does anybody have experience with this issue in the cold
regions of the US like Colorado or Montana?  Do you always mount the
inverter inside in those cold regions?  
 
Thanks,
Randy Sadewic
