Temperature wise, it’s probably fine if things have been running.

But loose power for a few hours in winter, and you’re now starting up from a cold-soaked condition.

If it merely “doesn’t perform well” when cold, letting it warm up is enough.

In theory one could have a power resistor and run that for a while before trying to start the concentrator if a temperature sensor reads on the chilly side.
