Any motor will need both a voltage and current to operate properly, and they
tend to draw more and more current as the source (inverter) voltage drops.

I built in Alaska for a friend. He & his wife are gone most winters
and the temperature inside the unheated home probably gets down to -30.

The third world will leave us to drown in our own pollution in 50
years if we don't get to work.
Either this country takes up its roll as leader or we hand over the

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
On thing I have noticed in many of our discussions is we sometimes forget that many of us are from very different areas of the country and what you think works great for your area are not possible in other locations. Many good solar areas are also locations that are not too hot and not too cold.
Hi Ray,
In Arkansas we used whole-house fans or just a box fan in the open attic access
hole to exhaust hot air out of the attic vents, closed the curtains on the
south-facing windows and opened the lower sash on the north-facing windows to
let cool air in.

Hi Joel;
I made a list of strategies we use a couple of emails back in this
string. I'll reiterate:
Here in Northern New Mexico we use adobes (lots of thermal mass) and
open up to the cool night air.
When I lived through Texas summers, you either ponied up for AC, went
to your mountain home
Interesting discussion.
Wrenches can figure out how to do just about anything, but just because you can
do something doesn't mean you should do it. The transition from
holier-than-thou to hipper-than-thou is morphing into cleaner-than-thou. Yet
death by pollution hardly impacts world population
