8.1. The SkyWind NG can also be used on buildings. Operation on buildings will work best at free-standing buildings, as well as buildings on the edge of towns or slopes (see pictures). If mounted in the town center the wind speed can, depending on the sites conditions, be slowed down by as much as 50%. Also make sure to choose the highest point of the house and check your site using the global wind atlas ( www.globalwindatlas.info ). -

Page 28: Operation On Buildings And Homes
………………………… 9.3 Operation on buildings and homes As of 2020 about 80% of all SkyWind NG micro wind turbines are mounted on rooftops or other building structures. All kind of different tower structures have been used by customers world wide. In Europe the satellite dish mounts of DuraSat GmbH from Germany have proven to be the most cost effective and most easy to install solution. -
Page 29: Structural Stability
9.4 Structural stability Due to the low size of the SkyWind NG the tower is not a part of the wind turbine as defined by DIN EN 61400-2. This greatly reduces cost as SkyWind Energy can manufacture, sell and ship the SkyWind NG without a mandatory tower system. -

Page 42: Initial Start-Up
14.1 Electrical inspection and mechanical test The installation of a SkyWind NG micro wind turbine is not complete until the following tests and inspections have been suc- cessfully performed on the completed turbine. The person installing the machine or mounting it to the building is responsible for compliance with this manual, as well as the state of the art. -
Page 43: Fine Adjustment / Noise-Reduced Operation
…………………………………………………… If you own a SkyWind NG battery charger version (12 or 24 V version), the test procedure is basically the same. Connect the laboratory power supply to the turbine cables at the charge controller input using suitable contacts. First check the direction of rotation at 5 V, then increase to 15, then to 25 V and check that the battery is charged. -
Page 44: Final Notes
Standard warranty on SkyWind NG micro wind turbines is 36 month. SkyWind Energy is liable for replacing a part under warranty but is not liable for de-/installation cost of any kind. It is in SkyWind Energy´s sole responsibility to decide weather a repair or replacement is performed. - Page 45 The installation must be done by trained professionals only! The installer must be qualified and accredited for work on AC electrical installations. Expert knowledge and full understanding of the complete manual is mandatory!

- Page 46 1. First Check You will need an original SkyWind NG turbine including the automatic storm control from SkyWind Energy GmbH. If you are not sure wether your parts are original or not stop the installation and contact SkyWind. ...
- Page 47 2. Site & Customer SkyWind NG turbines must be installed above all obstacles that might disrupt a free and continuous airflow. Remember the following rule: BASIC RULE: When your head is at the height of the turbines nacelle you must not look into any trees, houses or other obstacles! You should see the horizon in any direction! ...
- Page 48 3. Visual Check Place the turbine as shown in the picture. Do not place the turbine on the back. This would lead to the metal deforming once the cover is removed. Check the turbine for any potential visual damages, bend parts etc.. ...
- Page 49 If these are too loose the turbines operation might be louder than expected. Check manual for details. Never use any other screws than those delivered with the turbine! In case of loss of screws please contact SkyWind Energy. Page 49 | SkyWind Installation Handbook...
- Page 50 7. Mounting Preparation Attach a fitting ring terminal to the end of your DC cable to ensure easy and quick connection to the inverter later on. If you use more than a single cable make sure that the connection is safe and durable (e.g. MC connectors). Mark the + and the - pole clearly and unmistakably! ...
- Page 51 10. DC Installation Of The Inverter Connect the inverter to the turbine using the far right red + and black - connectors la- beled with „DC INPUT“ (yellow marking). Make sure that the polarity is correct! Mount the dumpload close to the inverter, but not below it. In case of too much power the resistor might become very hot.
- Page 52 13. Finalizing The Electrical Installation Check the whole electrical installation and write down your wiring diagram to check yourself. Document all settings of your storm control system and of your inverter by taking pic- tures with visible dates. Without photographic documentation your warranty is void. ...
- Page 53 15. Installing The Blade Check that the turbine systems main switch is in OFF position. This way the turbine can not start up after installation of the rotor blade. Install the patented SkyWind rotor blade as the last part of the installation. The blade is made of two pieces.
