XW experience? [RE-wrenches]

[Mark Edmunds]

Doug, Wrenches - thought I should chime in here to help clarify what has 
been going on with the XW product series.

* we shipped over 30 units back in Sept 2006 for field trial deployment 
(just prior to Solar Power 2006)
* at Solar Power 2006 we did not launch XW, however we did show it as we 
were getting close...having just dispatched field trial units.  (Launch 
means that it is available from our distributors.)
* while field trial hardware has worked flawlessly, we did uncover 
software bugs (particularly around grid tie and parallel operation) that 
needed to be solved prior to commercial shipments (they are solved now 
with lots of bug-free run time).  As the XW uses all digital controls 
this proved to be a more difficult undertaking than we 
thought...BUT...we will not release this product without it being ready. 
 We do apologize for the delay.
* we began commercial shipments in July of this year once we got our 
final regulatory approval in June.  Quantities have been very small (~ 
20 XW Inverters with BOS and MPPT) as we work through the production 
ramp up phase.
* prior to Solar Power 2007 we will fulfill many distributor orders so 
we can truly launch XW in our booth...and indicate to dealers that it is 
available from distribution.

As far as the XW MPPT being "me too"...(sarcasm noted (-: ), there are 
some differences like; no internal cooling fan (passive cooling via 
large heat-sink), dynamic MPPT (like a grid tie inverter) not 10 minute 
sweeps, integrated ground fault detection, 5 year (vs 2) standard 
warranty, fully networked with XW so config can be done off a single 
display (without requiring a "hub").  

Doug, stop by the booth at Solar Power for more details...


Cheers,

Mark
