Southwest Wind Power provides excellent service and support.
When my unit failed, I called on the telephone from Greece, and they talked me through some tests. When we determined that the regulator board had indeed failed, they sent me a replacement part, all the way from Arizona to Europe, at no cost. Excellent!
The phone number in Flagstaff Arizona is +1 928 779 9463.
Replacing the regulator board took quite a bit of skill and dexterity, even for an experienced technician like myself, but if you are careful, and follow the instructions, most anyone could do it.Howard [ Just Imagine ] 22-Jan-2008
