Gilana,
This info is from the Air Wind Module/ Air Marine. Version 1.9 owners manual Spec Page.
Rotor Dia. 45 in. (1.14 meters)
Shere of Operation 48 in. (1.22 m)
Weight 13 lb. (6kg)
Length 26.5 in. (0.67 m )
Start up wind speed 7 kts. (3.0 m/s)
Rated Power 300 watts
Peak Power 450 watts
Regulator Set Range 12 volt model 13.8 to 17.8
24 volt model 26.0 to 36.0
Fuse
Current 12 volt model 40 amps
24 volt model 20 amps
The graph for the Air Marine power curve shows start up @ 7 kts
10 kts = 15 - 20 Watts
15 kts = 75 Watts
20 kts = 150 Watts ( here is where the curve takes off)
25 kts = 320 Watts
30 kts = 385 -380 Watts
35 kts + = 375 Watts (graph flat lines there)
You will need to do the conversion from watts to amps, if you are seeking that info. All this is taked directly from the manual verbatem, except for power curve info which I pulled off the graph. I only included the info for the Air Marine, but the Air has the same spec's with a slightly lower power curve.
Are you aware that these units have internal regulators that are field adjustable and can be used stand alone, or with an external
regulator.
I run mine thru a Flexcharge NC 25 charge controller totally isolated from my
solar system which has it's own charge controller ( BZ Products 250 )
Let me know if you need any more info or want a PDF of the manual.
Hope this helps
