|
| Mount |
1.5 inch schedule 80 pipe / 1.9 inch OD approx 40 mm |
| Direct Grid Connect 240 V AC |
220/240 V AC 15 amp breaker recommended for
the AC connection |
| Rotor |
Diameter 6' 3" (75")
Swept Area: 30 Square Feet |
| Rotor Material |
Stainless steel hub with 1/8" thick Aluminum blades |
| Rated Output |
1800 watts at 30 mph "real world" |
| Instantaneous Wind-speed |
Max rated output by industry standard
5.0 kW - aka - I. L. S.
rating or B* S* |
| Start-up speed 7.5 mph |
Grid connection @ 7.5 and maintains to 5
mph, with usable power before other systems connect. (most are 12 mph) |
| Performance Range |
Provide maximum possible production in
common winds of 7.5 to 17 mph, Which increases monthly Kwh production. |
| Max Wind Speed |
Electronic braking applied at max power of
2100 Watts, (or) at 33 to 37 mph wind density dependant. |
| |
|
|
Safety |
Brake
can be applied and maintained for extended periods of time through input
controller. |
|
This
unit produces voltages up to 750 volts AC and care must be used if
exposed wires are present. |
|
Features |
Low start up speed due
to low cogging and resistive torque design. |
|
Gearless direct drive
low rpm generator |
|
High standard, quality
components for use in harsh and extreme environment for wind turbines. |
|
High efficiency
and tuned for max production in common wind speeds (not to be confused
with full output) |
|
Excellent heat
dissipation due to the winding running on the outside edge of the Aluminium alloy outer frame |
|
Low mechanical
resistance energy loss |
|
Generator is designed
using specially selected material and treated to resist corrosion and
oxidation. |
| Designed for
reliable long
operational lifetime under long-term full output. |
|
Designed with 15
to 20 years of
operation in mind. |
|
Brush-less Design (no more changing brushes every couple of years) |
|
Quieter than most other grid connect system
on the market. |
|
AC output from the unit connects to grid module in your home. (No
electronics in the head to fail.) |
|
Electronic braking and dump to load in event
of grid failure, high wind events, storms, etc. |
