. . . I just looked at this Xantrex: https://www.donrowe.com/Xantrex-806-1220-PROwatt-SW-2000-p/806-1220.htm
More expensive, for sure but the specs say:
1800 watts continuous power output
2000 watts for 5 minutes
3000 watts surge (peak power)
Pure sine wave output (< 5% THD )
5 minutes @ 2000 watts? Am I reading that right - that's differerent from peak power, I assume? I'm thinking that would easily run my MW
Lol!! We used to own the Xantrex ProWatt SW2000. The above specs are correct. It's an 1800w, not a 2000w inverter. Primary reason we purchased it was for the very low .5 - .6a parasitic current. Ran our microwave fine for about a year using 2, GC2 6v leadcell batteries. The microwave has a 1050w line input power rating; however, in reality it uses almost 1300w (why, I don't know; very little DC or AC voltage sag).
After we upgraded our TC with a DIY 200ah lifepo4 battery pack and 40a dc to dc charger, we wanted to run our a/c, too. The ProWatt SW2000 was a no-go, even with a Micro Air Easy Start installed on the a/c. Not surprising because the 1800w ProWatt SW2000 has very low inrush current (only 3000w *peak* power vs. 4000w *peak* power for most lower tier 2000w inverters).
Sold the ProWatt and upgraded to an Aims 2000 watt ?PWRI200012120S inverter. After a year and a half and 30,000 mi., the Aims continues to run the a/c unit (1400w), microwave, hair dryer (1800w), vacuum cleaner, etc. flawlessly---lots of very, very hard use in temps as high as 110 deg. Huge kudos to our dc to dc charger for keeping our lifepo4 charged while we're on the road. Without it, we'd only get a fraction of the use out of the inverter (and a/c unit) that we do.
