Outdoor VFD options

I have an application for an outdoor VFD.

We typically provide an outdoor rated VFD (Lenze SMVector or Allen Bradley Powerflex 40) but both show operating ranges of -10 to 50 deg C.

In doing some research, nearly all VFDs I've researched so far operate in this range. I'm guessing it has something to do with the capacitors in the drives.

Does anyone know of an outdoor rated VFD that would operate below -10 deg C?

Thanks.

Nord has some -25°C outdoor inverters.

We use Schneider Drives out in the OILFIELD very harsh environment HOT/COLD without any problems.

Cold Weather VFD

Friend of mine told me about Eaton PowerXL series vfds that have a cold weather function that can get them to -20 to -30 C. No idea how good they are but it's an option.
