What inverter is appropriate for a 10kW high-leg delta solar application?

Hello,

I'm working on a 9.2kW project with a MecaSolar tracker. I have concerns as to the appropriate inverter for the application and I was wondering if you could point me in the right direction. The application's power pole/utility intertie is a Delta, 2 hv, 2 pot, three phase/4 wire system. So, across the legs, 240/240/240 with a high/red leg. Here's the link to show an example... http://en.wikipedia.org/wiki/File:High_leg_delta.svg.

Since the SMA 10kW is designed for three-phase delta 208V applications, I'm not sure that this inverter would be appropriate. Seems as though this would be an unbalanced load across the legs.

The SMA 5-8kW units have the ability to set all three phase legs separately. The grid is an open/stinger/red leg Delta three phase for an irrigation pump.  Basically across the hot legs the voltage is 240, but testing legs to neutral, one leg measures 277.  It would be an unbalanced load. Instead of the 10kW, probably use two SB5000 units?

Thanks!
