I have a number of these Magnum sine wave inverters (various models)
out in locations where the inverter undoubtedly gets very cold at
times. I do not know if this matters, but all of my Magnum inverters
have a "remote" as part of the installation, even if it is usually
right there. Last week, for an absentee owner, I went out on-site
where AC electricians worked on the AC distribution. The Magnum MS AE
240V in an unheated power shed, as well as myself, were very cold by
the time they were done. It restarted from the remote with no problem.<br>
Until reading John's question I had forgotten that one time I tried to
start my own Magnum in my workshop (which is only sometimes heated by
wood) from the little button, and it did not start. I had the remote
unhooked for some reason. I plugged it in, and the inverter started
from the remote. I never gave it another thought.<br>
I also would be curious about similar serial number and manufactures
dates as Warren has pointed out, hope this helps. These have been very
good inverters for us in many applications. My home system has a pair
of OutBack FXs.<br>

with those inverters, though not unheard of with electronics in
general. From my experience it is usually due to an electrolytic
capacitor being out of spec (or wrong one)., but can also be from some
solid state component, or even the main processor or ROM being out of
spec for temperature.</font></div>
