State-Of-The-Art Design
The E48 is based on the latest technology, with full blade pitch control and our exclusive ASC (Active Stall
Control). ASC offers both the advantages of pitch-controlled blades and the stall effect, used by classic stall-
regulated wind turbines. Due to the pitch-controlled blades, the rated power level can be tuned precisely,
eliminating effects of differences in air density, blade-surface contamination etc. This way, the uncertainties in
the rated power level can be avoided.
This guarantees maximum power output for all environmental conditions without overloading the drive train of
the turbine. Besides providing power control, the blade pitch system is also used to accelerate the blades from
idling to operational speed and bring the rotor back to a safe idling situation in case of a grid loss or any other
functional error.
In addition, the E48 has a double speed generator. In wind speeds up to 7 m/s, a 120kw generator is in
operation, assuring better performance in lighter winds, and with higher efficiency. Above 7 m/s, the 600kw
generator is employed. The result is optimum performance and increased production throughout the wind
speed range.
FEATURES
* Sized Right For Smaller Projects
* Installs where larger MW turbines can’t go
* Lower installation costs than MW machines
* Modular Strategy: Spread downtime risks
with multiple units
* Large rotor for high kwh production
* Available for projects under 30MW
Design
* ASC - Active Stall Control; combines
aerodynamic stall with blade feathering for
full control and increased production
* Designed and engineered by professionals
* All components designed for a service life
of at least 20—25 years
Safety
* Fail-safe blade feathering in the event of grid
loss
* Independent over speed safety systems
Electrical
* Utility-standard electrical system
* Specially designed soft start for smooth startup
* "Double speed" generator for more efficient operation in low wind speeds, resulting in increased kw/hour
production
Control
* Special designed microprocessor controls
* Optional remote control and monitoring via modem link
Field Proven
* In operation since 1998
* Over 70 units in successful operation
* Fully certified by various international organizations

The new Enertech® E48 is the ideal wind turbine for smaller wind projects
across North America. With a large 48m rotor, just two E48’s can rival the
production of larger MW-class turbines.
The Right Size
The E48 is ideal for smaller projects for many reasons. First, it can be
installed on crowded sites where MW machines often times can’t. Second,
installation costs are generally lower because transport trucks, foundation
requirements and installation cranes are smaller. A third advantage is
modularity. A 1.2 MW project could be filled by one MW-sized turbine, or two
E48’s. With a MW machine, you lose 100% production when the turbine is
down for repairs or maintenance, but only 50% by shutting down one E48.
And don’t let the E48’s 600kw rating fool you. It has an oversized rotor
compared to 600kw turbines of the past. This enables the E48 to produce
more kw/hours per year than similar rated models. And kw/hours are what
you are paid for.
