Esteemed Wrenches,

Is there any possibility at all I can install a 230/400 50 Hz Sunny 
Island Micro-grid in the U.S. or Canada and have it meet code?  Is it 
the neutral and grounding that's going to prohibitive?  Or is there a 
way around that?  Anybody ever done it and gotten it through an inspector?

I'm working on an island mico-grid and the European standard would bring 
us higher voltage - larger multi-cluster boxes from SMA (the US version 
only goes to 60 KW whereas the European version goes to 300 KW) perhaps 
better SI support from Germany, and access to a wider variety of energy 
efficienty appliances.

One can only ask!

Jeff
