If you are referring to 240V AC, then in the US we do use 240V, altho it's split phase. Most large electric appliances use 240V (dryer, water heater, oven, etc). But I'm going to assume you already know that and was wondering about 240V on a single line.
Most of the inverters that are discussed here on the forums are 240V AC single line version. And unfortunately, the large ones that have decent prices don't support 240V split phase (2 x 120V legs). There are a few, though. So that's good.
If you did get the single phase 240V inverter and needed the split phase, the only way to really do it, with that inverter, is to use a 1:1 transformer with a center tap (this provides Neutral). There was someone on here who got a transformer, but I don't remember who it was. But I think the price they got it at was about how much it'd cost if you were to build one (tho, the unit was bought off eBay, if I remember correctly). Maybe someone else can chime in and say who it was with the transformer.
