Wind query [RE-wrenches]

How about hooking a AWP 3.6 high voltage unit to the easy wire?

I have been asking for around 6 months and still no answer from SWWP on a
simple part for a 1500. A lot of their larger units they have seem to have
parts scattered all over the area.
(some of the smaller ones also, as I think about it)!!

Roy and I had this conversation about an AWP last night, strange.

Wrenches, some wind advice, please,
    In 1998 we designed and installed a PV/wind/diesel stand-alone system
for a rancher in the eastern plains of New Mexico. He brought to the design
a depression-era 32V "Wincharger" two-blade wind gennie with original
controller that he had bought at a ranch auction, I believe. This was not a
Jacobs, and early on Windy Dankoff advised me that it wasn't the Jake's
quality. So I designed the system around a World Power 12-1600 EZ-Wire
center for both wind and a small PV array. I did it this way because 1) the
controller and a governor adjustment allowed for operation on a 24V system;
2) it provided a dump load; 3) I got rectified DC out of 3-phase wild AC
from the bird; and 4) I didn't believe that the old bird would keep running
for long, and I wanted to give the client an easy way to replace the old
bird with a modern unit without redoing the rest of the system.

    All happened as expected. The unbalanced blades started coming apart in
a couple of years and eventually I heard that a part or two blew over to the
east 40. The client has asked for a quote on a new gennie. We had originally
specified the controller for a Whisper 1000, which is more or less the
Southwest Windpower H80. World Power sold the EZ-Wire center without the
bird, but SWWP doesn't want to sell the bird without the EZ-Wire II (wind
only) controller at a reasonable price. So, my questions:
1. Is the H80 the best choice for this particular application? (good
seasonal site, adequate ~50' 4-leg freestanding tower, a dozen 5-year-old
L16s showing signs of weakening) The client is on a pretty tight budget.
2. If so, should we try to buy just the bird, haggling for the best price we
can get for the client, or should we use the EZ-Wire II controller and a
separate charge controller for the PV? (In other words, is the newer wind
regulator a major improvement?)
3. Is there a better way?

Thanks in advance for the collective wisdom, as usual.
