That is $858 total and it is only 2000W 40 Amps. For $700 he can get a 4000W 60 Amp Hybrid with the features listed above.

Example: Hybrid Solar Inverter Pure Sine Wave

MakeSkyBlue is one of China's largest supplier of Solar equipment and a Government contractor. They are not some fly by night company.

That would be better, except the one you mention is 230v, and I'll bet a cookie it's 50hz, as well. The only 120v unit listed is
A: only 800w, and
B: out of stock.

There are probably others...

120/230V per the datasheet . How sure how to interpret, 2000w @ 120V , 4000W at 230V ....?

Hm that's a different set of data from the first link.  Which one is correct?

Re: 2000w @ 120v vs 4000w @ 230v... That's easy. The CURRENT is the same, and that's what determines the size of the components.  You see it in charge controllers all the time. they're rated in amps, so the wattage goes up with the voltage. 

So by going with a higher battery voltage you save money on controllers (and wiring).

My charge controller is rated at 50 amps, 600w at 12v, 1200w at 24v.  Sadly I'm stuck with 12v because of the engine.

I would trust the datasheet over the eBay seller. Too often the eBay sellers are just salesmen.
Also I think the eBay sellers say must be 230V so they can advertise the higher power and avoid saying 2000W @ 120V.
One thing I like about these Hybrids are, most are stackable. Later on if you need more capacity, you add a second unit, some can stack up to four units.

There are other besides MakeSkyBlue with better documentation. The Chinese are like the Japanese back in the 80s -90s. Good products but idiotic English documentation.

Reading a little bit further it may mean 120V/230V AC input, 230V output. Like you  said there is other fish in the Sea.

I'm baffled, what is there to be sorry about?

Out of curiosity, I sent this question to the seller in the eBay link:

"Is the AC output 230V single phase only. If so what is it doing on the US eBay site? In the US we use 240V split to get 120/240."

This is what I got for an answer:

"New message from: powerrme

It works for two 120V in US. But your load device should be 240V also. Thanks."

Duh! 🙄

Clear as mud...  I THINK he means 120/240 split, but without better documentation I wouldn't take the chance.

Or choose a Charge controller/Inverter with a Generator/Utility input.

I wondered how I could do this good to know
