[RE-wrenches] Inverters and cold temps?

[Jesse Dahl]

The post by Dan from Exeltech got my mind on this.  

The warranty is what always makes me stay away from inverters outside.  It sure would make some of my installs easier if I could mount the  inverter outside. 

Any other inverter brands outside with no problems?
