Maybe the easiest and simplest thing to do is grab an el cheapo Chinese inverter in an European configuration of 240? volts 50 Hz for your battery bank.

I tend to go for lowest price, figuring everybody else is just ripping me off.
But that's not always the case.  Here's an inverter story that should scare you good:

Lots of other interesting stuff on that website if you are into electronics.

I've used a bunch of PowerBright and Wagan modified square wave inverters (I refuse to call them modified sine wave) with reasonably good luck.   Keep all such gear away from any moisture (such as a puff of powdered snow).  Expect fireworks when you eventually hook them up backwards to you car battery some dark night.  Mostly work well enough, but there are reasons for building inspectors to insist on UL 1741 certified gear.
