Efficient inverters for stand alone power systems? [RE-wrenches]

[Jim Easton]

<x-flowed>

I recall that the old UPGs were internally quad inverters that had quite low 
quiescent currents.  On a larger scale, the OutBacks will fire up more 
inverters as needed in multi-inverter installations.

I am wondering if there might be a market for a transfer switch that would 
allow one to integrate a system with a small and a large inverter so that 
the large inverter came on-line only when needed.
