Anyone know about these inverters at all? For the price, they look damn impressive, if the claimed numbers hold up.  I'm looking for a LF inverter who's sole purpose is to run a ⅓hp submersible pump when the tank calls for it to. And to run power tools occasionally as well.  My plan was to set up a closed circuit (pressure switch-inverter-bank) with a couple time delay relays for on and off, so that the inverter never starts under load, and powers down when the pressure switch is satisfied, thus avoiding idle loses unnecessarily.  A high efficiency, lower wattage Samlex 600sa powers everything else on the main circuit, operating from the same bank.   As there seems to be a lack of stand alone high power LF inverters that aren't of dubious Chinese origin, this one here looks like a winner. Any thoughts?

I didn't see anything about ETL certification, if that's an issue for code/insurance purposes.

Other than that, it looks like a lot for the $ if it works as advertised.

Looks a lot like a Magnum.

What makes you think this is not of dubious Chinese origin itself?

Based in the US, according to every vendor, and there website.

I contacted them requesting location of manufacture and the emailed reply I got was that they were designed in the US, and produced in a mainland Chinese plant.  FWIW I order stuff from China occasionally via Alibaba, but I only order from plants that have a track record or that a friend has inspected and ordered from.  It really boils down to the plant that makes it, and the level of QC that is going on at that plant.
