The D400 'StealthGen'

The StealthGen Wind Generator is a new direct-drive wind generator, designed for a variety of microgeneration applications. It is exceptionally quiet and vibration-free in operation, qualities that are of paramount importance for any wind generator operating in close proximity to people. The StealthGen features a powerful 3-phase alternator, and computer-designed rotor blades optimised for low speed, user-friendly operation.
This innovative machine is extremely efficient in low wind speeds, yet is capable of sustained power outputs of over 500 watts in higher winds.
It is small and light enough to be easily attached to most building structures. Given average wind speeds at the site of around 12 mph, one D400 StealthGen could realistically provide 15 - 20% of the average home’s annual electricity requirement.
Inexpensive to purchase and virtually silent in operation, once installed the StealthGen is no more conspicuous than a satellite dish.
Distinctive and elegant in design, the StealthGen is superbly engineered for long, trouble-free service, and is available in 12, 24 or 150 volt grid-connect variant.
Due to the StealthGen’s low cost, it is perfectly feasible to install several machines.

Regulation :
We generally recommend that the D400 is installed together with a regulator to prevent battery damage through overcharging.
A stop switch can also be incorporated as part of the installation.

2. Generating interest in wind power


Small wind turbines sited within the urban environment have the potential to make a significant contribution to the attainment of fuel poverty and carbon abatement targets.
Eclectic Energy Limited has worked closely with INREB Faraday, the NGO tasked with the development of these technologies.
Conventional wisdom has largely precluded the mounting of wind generators on buildings due to the unacceptable noise and vibration associated with such installations. Eclectic and its research partners have overcome these problems in the development of the D400 and StealthGen technology.

The power produced can be used for:
Grid connect – G83 inverter technology
Battery inverter AC systems
DC direct supply to fluorescent lighting
DC supply water heating
Battery charging (transport)
Hybrid ground source heat pump systems
Hybrid micro wind/ photovoltaic systems

The turbines can be installed singly or in multiples.
Each micro wind installation will produce between 0 and 10 kW hours per day, depending on the prevailing wind speed. A realistic annual yield would equate to 1.8 kW hours per day.
An average family house uses some 10 kW hours of electricity per day.
