The basics

Who is Semtive?
Semtive is an energy company that offers high quality, safe and affordable vertical axis wind turbine systems for urban, remote and humanitarian use. We’ve made great strides in technology and R&D in the clean energy industry during our years of operation.
What is the company’s vision?
Semtive’s vision is to be the global impact leader in decentralized energy generation through the democratized use of renewable power – an efficient and socially impactful clean energy solution that can be employed by anyone, anywhere in the world.
What is Semtive’s core product?
Our core product is the Nemoi S, a 600W wind turbine.
Why wind?
The wind is an abundant source of renewable energy with no carbon emissions or pollution. It is a clean, sustainable source, ensuring energy generation 24/7.
Are Nemoi turbines environmentally friendly?
Wind power is a safe, green renewable source of energy. More than 95% of the Nemoi turbine is made from aluminum, a highly resilient and recyclable metal that is resistant to corrosion. Nemoi turbines are also virtually silent, generating less than 38 dB of noise (less than a whisper) when operating at the highest rated wind speed. Nemoi turbines spin at very low rpms, making it safe for birds and other wildlife.
Where are Semtive products manufactured?
Currently, all our design and manufacturing is done in the USA. However, our manufacturing process allows us to produce the same high quality systems locally, in any market in the world. With this local approach, we can reduce our carbon footprint and shipping costs to customers.

Tech Specs

Why vertical axis wind turbines?
Semtive manufactures the Nemoi turbine using a vertical axis design because of the efficiency of operation at low wind speeds, typically seen in urban environments. This design allows the turbine to efficiently capture wind from any direction. Additionally, the Nemoi turbine generates very little to no noise, and does not require cranes or guide-wires for stabilization, making it safer and more suitable for urban areas – and more environmentally friendly.
How easy is it to set up a Nemoi turbine?
The Nemoi turbine is lightweight and can be assembled in less than an hour anywhere in the world, operating with equal efficacy on or off the grid, from densely urban to rural environments and areas in urgent need of humanitarian relief. Installation can vary and will depend on the mounting system and location.

Turbines

How much wind speed does the Nemoi turbine need to generate energy?
Due to the design and blade configuration, our turbines can generate electricity with wind speeds as slow as 3 mph.
How much wind speed does the Nemoi turbine need to generate energy?
Due to the design and blade configuration, our turbines can generate electricity with wind speeds as slow as 3 mph.
How much power can a Nemoi turbine generate?
The power generation depends on the model of the Nemoi turbine selected, S or M, and the weather conditions of the location where the turbine is going to be installed. To see each Nemoi model’s power curve, please download the corresponding brochures or get an estimate here.
How does the electrical connection work?
The Nemoi turbine can be connected to the electrical grid or operated off-grid, and can be customized for end user applications. The system generates single-phase AC power through an inverter/controller that is synchronized to the grid to offset residential power usage or deliver excess power to the grid (depending on the application).
What safety features does the Nemoi turbine have?
The all-in-one inverter has automatic derating functions when operating in adverse weather conditions. The inverter has an anti-islanding feature that prevents back-feeding the grid in the event of a power outage. This feature ensures electricity is not sent from the turbine to the grid during the outage, guaranteeing the safety of grid maintenance workers. Also, the turbine has electromagnetic brakes that stop it from overspinning.
How does the Nemoi turbine attach to the rooftop?
The mounting system will vary depending on the application and surface of installation.
Can I adapt a Nemoi turbine to an existing energy generation system?
The Nemoi turbine can be adapted to existing energy generation systems as solar panels, creating a hybrid system. For better advice on this matter, please contact your local authorized installer.
Can I transport the Nemoi turbine?
Thanks to its modular design, you can disassemble the Nemoi turbine in a few minutes and transport it wherever you like.
How can I purchase a Nemoi turbine?
To purchase one of our products, please contact us at sales@semtive.com.
Do you provide warranty?
We offer 20 years warranty on our Nemoi turbine, according to the warranty certificate from our IOM manuals. This warranty is subject to a correct installation of the products, in line with the standards provided in the installation manual.
What temperatures can the Nemoi withstand?
The turbines can operate in temperatures as low as -30 degrees F. However, the units can be customized to operate in lower temperatures if necessary. There is no upper limit for the operation of the turbine.

MOVE Systems

What is the difference between the MOVE and the MOVE+?
The main difference between the MOVE and MOVE+ is the technical specifications such as wattage, battery type, life cycles and max discharge rate. The MOVE versions are customizable that and can adjust to the customer’s specific needs. For more information, please refer to the Products Spec Sheet.
Are the MOVE systems mobile?
Yes, the MOVE and MOVE+ are all-in-one plug and play renewable battery systems in a portable package comprised of a small scale wind turbine and solar panel, completely modular and customizable to customer requirements. Depending on the enclosure, the MOVE system can be easily transported to any site or remote location.
Are the MOVE systems stackable or can they be used in tandem?
The MOVE systems can be connected in tandem, however each system will still be comprised of its own set of batteries, Nemoi turbine and solar panel. Depending on the enclosure the MOVE systems can be stackable.
