Small AC motors and Inverters
Disappointed that my ancient Mod Sine Wave inverter (140W cont, 200W surge) shuts down with a 120W coffee grinder. Works ok with the 400W (cont) MSW inverter built-into the truck, though a little ...

The Vector 2000w (4000w surge) manual seems to say that the surge ability also comes from the specified ANL slow blowing fuse that goes on the positive input wire.
They do specify the ANL fuse size to be for the 4000w surge amount, not a smaller size fuse that would be for the 2000w rating
That makes sense to me. The fuse as protection of the last resort.
The old MSW I was trying to use has a small blade fuse, but it was the internal electronics that shut it down when overloaded. Don't recall ever having blown a fuse with it. But the internal overload protection is very fussy.
Which is probably just as well, as I previously destroyed a smaller inverter that would actually run the grinder slowly for awhile then cut-off. Wait awhile, repeat, eventually get ground coffee, and eventually it died. Hmmm, sounds like what you were doing with the Uwave and the Cantire/Xantrex. Hopefully I've learned my lesson.
