(1): Compare manufacturers' wind generators by swept area, or by electricity production (kwh/month) at the same average
wind speed (such as 5.4m/s = 12mph), or by power (watts) at a wind speed below furling such as 10m/s = 22mph. Peak
or maximum power rating is a poor indicator of electricity production because rated & cut-in wind speeds differ widely. (2):
Order H80hvlv, 80hvlv or 175hvlv which include EZ-WIRE & transformer for long wire runs. Otherwise identical to lv mod-
els. Order Controller EZ230B for unregulated 64-240vdc battery charging. Order Controller EZ230H for electric water/
space heating. (3): Order H80hvp for direct electric water pumping includes pump motor controller EZ230P. See Price
List for all pumps. (4): Except Whisper H80hvp wind generator is shipped at nominal 120 volt setting for 230vac motor
variable speed operation. (5): Wind Generator Mounts to Inside of pipe or tube. Mounting insert can often be modified to
fit a smaller inside diameter. (6): PP30 is injection molded, fiberglass filled, custom polymer. CRF is carbon reinforced
fiberglass with foam core. All specifications subject to change or correction without notice.
