You can stack three OutBack FX series inverters into a three phase 
configuration for 120/208 VAC "WYE" output (4 wire) with a HUB4 or 
HUB10.  The two slave inverters can even go into search mode when no 
three phase loads are operating.  

You can charge from either a single phase or three phase generator or 
grid. The two phases not connected to the single phase AC source 
continue to invert while the other phase charges - this allows single 
phase power to be made into three phase power (although is a round about 
manner).  

Phase "C" can also have additional inverters connected in parallel for 
higher output if a mixture of single and three phase loads are expected. 
We will in the not so distant future be able to have more than one 
inverter on phase A and B as well.
