looks good with me.. seems it has a remote on / off switch . wonder if the voltage display is the battery or output voltage. Did not see a switch to display power?

I need to know more than what the seller is lying about. I've looked and can't find any for sale at $1799, so that to me is a fictitious number like most "Suggested Retail Value" that the item is never sold for.
There is an optional wired remote switch sold separately for $25. I did buy this one, $211 shipped.

That looks like a generic Chinese no-name inverter such as are sold under a myriad of names by everyone and their uncle. It's a complete crapshoot buying something like that - at the very least, derate it by 50% to get a real-world usability and some semblance of reliability. In other words, if your actual electrical needs are for a 2000W inverter, buy a "4000W" Chinese one, then still start praying! The FETs are usually the first things to go, but if you're handy with a soldering iron they can be replaced.

Caveat emptor.

Yes, price out say an equivalent Magnum, top-notch trusted brand.

Also Vanner, Victron, MasterVolt, Sterling, Outback, ProMariner.

Xantrex is good but terrible CS attitude.

Samlex and Tripplite solid middle ground. I've also heard Morningstar is good.

These generic Chinese units, hey, you might get lucky. Cheap enough to buy a spare. . .

Some say AIMS is good enough?

GoPower gets some kudos, decent CS rep.

The inverters made by Cotek in Taiwan are pretty good - Samlex, Go Power and others are mostly made by Cotek*, so just buy the least-expensive version and not pay too much attention to the name on it! Obviously they're more expensive than the mainland Chinese stuff, but they're cheaper than USA-made ones such as Magnum or Exeltech. However, a used Magnum can be a better deal than a brand-new Asian one - Magnums are fully field-serviceable and can be rebuilt to factory standards whenever needed, which shouldn't be too often.

Ya pays yer money and ya makes yer choice. What's cheap initially may sometimes end up costing you more in the long run.

* Just don't go bragging to your friends that you prefer to use Coteks . . .

Moral of the story is that price is a bad measure of quality for inverters

I'm still happily rolling with my cheap 1000 watt Bestek. MSW inverter, they make a 2000W unit as well. Mostly I use it to run corded power tools, but I used it to run my freezer for over a year.

My Xantrex 2000 has been running almost non-stop for 4 years. Powers fridge and sometimes Mary's hair curler thing.
