large -48VDC inverter recommendation [RE-wrenches]

[Christopher Freitas --- OutBack Power]

The current draw of the inverter will be over 4000 amps at 48 vdc for a 
180 kWAC inverter system - impressive.  I know it is actually done in 
the telcom world - just thought the current levels involved sounded 
wild.

Technically, it is possible for us to do this with the OutBack FX series 
- and we do plan on doing it - we just need to make a master control 
unit out of an inverter control board and a AC board - we already have 
the redundancy working in the present product (except that we use one FX 
inverter as a master - all the slaves inverters can already be "hot 
swapped" or shutdown without any issues.  With a master control unit all 
the inverters will operate as just slaves. 

What is your the time frame required for the delivery? 

You might talk with RMS electric in Boulder, Co - Mark or Jan - I know 
they have sold some large telcom inverters in the past that were similar 
(www.rmse.com).
