Product Description

Our Heavy Duty Mallard SP73 is built very similar to our Economy Mallard SP73 but with the addition of very strong heavy duty bearings and thicker metal used in the frame.

Our Mallard SP wind generators produce maximum power for charging your off grid power system. The Mallard SP is built with axial flux technology for maximum charging power.

The Mallard SP 73 has a 7 foot 3″ blade span.

The SP is built without any metal behind the coils which means that it starts up much easier because the magnets are not fighting against steel. This allows the SP to start producing power in breezy condition before smaller low wind generators will even start spinning.

Mechanical Tilt Option:
For areas that get winds higher than 55MPH we do have an optional high wind attachment available. With this attachment, the SP will tilt up out of the most forceful part of the winds. It will continue to produce power while staying safe from the force of the storm.

Our wind generators are built with strong magnets and a strong frame built to last.  They are tested every step of production and built to order.  We ensure that everything is working properly and to full capacity before shipping them.

If you need to run the power for longer distances from the wind generator to the storage batteries use the 24 volt wind generator with a 12 volt battery system. By doing this you will have less voltage drop.
