Hello. Thanks for any help/suggestions anyone has. Location is a field in the middle of no where with temps from -20f to 120f, no grid, just needs to turn on and stay on without any interaction. I've currently got a well site ( off grid ) that has two 56vdc 5amp panels currently wired for 110v...

Looking for an OUTDOOR(-20f through 120f) 110vdc to 110vac invertor, needs to be able to handle around 20amp. doesnt need to do ANYTHING other than a dumb, ALWAYS ON invertor. Any help, new used, maybe questionable use of old microwaves, suggestions are welcome.
