Xanbus Network with no XW inverter? [RE-wrenches]

[Mick Abraham]

Salutations~

I've sent a couple of XW MPPT charge controls to Africa for use by 
Christian missions. 

(The very first XW control that I shipped over was DOA. That's 
consistent with Abraham's Corollary to Murphy's Law: "The further a 
product is shipped, the greater the chance of failure." But I 
digress...)

After some major hassle with the swap, things are working OK and the 
client wants a third XW controller. The installer particularly likes how 
the Xantrex unit is passively cooled, so here's hoping these controls 
can survive the African heat long term. "Full output current up to 45 
degrees C without thermal derating" (per Xantrex literature)  sounds 
promising...

The client has now asked me about the Communications Gateway: 

http://www.xantrex.com/web/id/269/p/docs/pt/5/product.asp

The Gateway "can monitor a network consisting of up to 20 single phase 
GT inverters and up to 8 XW devices: inverter(s), Charge Controller(s), 
SCP, and AGS," says the spec sheet.

My customer doesn't have a Xanbus network running nor any XW inverters 
to provide power for the network. If we buy the System Control Panel 
plus the required external power supply (per page 2-3 of the SCP Owner's 
Guide), will the Gatework work even though there is no Xantrex inverter 
in this off-grid network?

Second question: How do I come up with an external power supply to run 
the network, since there is no XW inverter in the system? The SCP 
Owner's Guide says to "Contact Xantrex for more information,." I'm using 
the Wrench List to do that, in case other technicians would like to 
follow the answer from Xantrex.
