MrWizard,
The 600 watt MSW one that I had, worked fine. This pure sine is 1000 watt. No matter how I figure it, It should be enough to start it. I got it to start it this AM and it is still cycling on and off as it should. If it works sometimes, I don't know why it doesn't other times. If anything, the input voltage is lower now than when I started it.
The other thing I have not mentioned is the fact that it states 2000 surge wattage. In my opinion, that should be enough for a 75 watt load.
glad its working .. right now..
but it not the 75w running thats is a problem
its the 900w or more spike on the compressor startup
and OH BTW FYI that 2000w surge might be divided across the outlets
on dual output and NOT all available on one device plugged into one outlet
it could be 500w run 1000w surge per outlet
this has come up before in other posts
and those surge ratings are typically 5~10 Micro-seconds
not the 5 Seconds or more it sometimes takes the compressor to get running up to speed
my Tripp-lite inverter will carry 50% overload for 60min
100% overload AKA 200% rating for 10 seconds
it weighs 23# , it has a nice big heavy transformer in it
thats a universe apart from the average light weight 5# inverter
all that power is available at ONE outlet when needed
