[RE-wrenches] Inverter temp spec for cold regions

[Tump]

Here in Maine I guess we've got the stupid Caps cause they don't know enough
to blow up when cold! My SMA inverter shouldn't work cause its been outside
now for 3 years! &  I guess that my SW4048s don't work anymore too. they
lived outside since 1998.We DO have some low temps & the only thing I have
seen is the LCD displays are not reliable.

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,
