FAQ - Frequently Asked Questions

  • What are the differences between horizontal and vertical wind turbines?
    The most significant differences between horizontal- and vertical-axis wind turbines are as follows: 1. A horizontal-axis wind turbine has its axis of rotation parallel to the wind stream, whereas a vertical-axis wind turbine has its axis of rotation perpendicular to the wind stream. 2. Horizontal-axis wind turbines usually use three blades, whereas vertical-axis wind turbine configurations, blade shapes and the number of blades vary a lot. 3. Horizontal-axis wind turbines pivot facing the direction of the wind. Whereas vertical-axis wind turbines are omnidirectional, they do not change orientation to match the wind direction.
  • Which one is a better option, horizontal or vertical wind turbine?
    Both turbine designs have their advantages. Vertical-axis wind turbines are more indicated when it comes to residential applications. They are easier to install and require less space. They don't have to be facing the right wind direction either. In a vertical system, air flowing from any direction can rotate the blades. They also handle turbulent winds better than horizontal wind turbines. Horizontal-axis wind turbines have higher efficiency ratings and are more likely to operate at higher wind speeds. They are better at converting wind energy into useful mechanical motion because their blades are perpendicular to wind direction, so energy can be generated the entire way through the rotation. You can make your decision depending on where you plan to install your wind turbine, how much space you have and how much energy you plan to generate.
  • What are the differences between ATLAS and ATLAS X models? Which performs better?
    Both ATLAS models are very robust, compact, and durable yet lightweight. ATLAS 7 can generate up to 7 kWh of electricity per hour. Its rotation starts at 4 m/s wind speed. Rotation and power generation start at even 3 m/s wind speed. It starts rotating at a lower wind speed as a result of its larger blades. It's larger in size and occupies more space. ATLAS X7 can generate up to 7 kWh of electricity per hour. Its rotation starts at 5 m/s wind speed. Rotation and power generation start at even 4 m/s wind speed. It is more compact than ATLAS 7.
  • Can I connect my TESUP Wind Turbine to a battery?
    Yes, you should connect your TESUP Wind Turbine to TESUP Charge Controller first, then link TESUP Charge Controller to your battery. TESUP Charge Controller is required to convert AC (Alternative Current) to DC (Direct Current) and control battery charging.
  • Is it possible to connect multiple wind turbines in one system? If YES, how?
    Yes, it is possible to connect multiple wind turbines in one system. We recommend a parallel connection of every TESUP Wind Turbine to your home electricity board. Every TESUP Wind Turbine should be connected to a separate TESUP Charge Controller which should be connected to a separate TESUP Inverter. Then different TESUP Inverters should be connected to your home electricity board. This is our recommendation and the safest method to make sure that every wind turbine can operate independently from each other and that the system can continue to generate energy in case of a product-specific problem.
  • Can I install my TESUP Wind Turbine at the seaside?
    Yes, you can install TESUP Wind Turbines at the seaside locations. But the lifetime of your product might be a bit shortened due to salty water and its diffusion into the air at the seaside.
  • How noisy are TESUP Wind Turbines? What are the noise level measurements?
    All of our wind turbines are very quiet, producing only up to 35 dB, which is less than half the sound of a vacuum cleaner. Noise levels of our products are regularly checked and tested in ideal outdoor environments for wind turbine installation.
  • Are all TESUP Wind Turbines tested? How can I know if my turbine is tested or not?
    Every TESUP Wind Turbine is tested before its packaging process at our factory. A video recording happens during every product's test process that shows product's serial number in a visible way. These test videos are shared with the customers just after the product delivery.
  • Can I use my solar panel and wind turbine together in the same energy system?
    Yes, you can. The systems combining solar panels and wind turbines are called Hybrid Systems. Different connections and components are required for the off-grid and on-grid systems. For the off-grid solution: The wind turbine is connected to the wind turbine charge controller that is connected to the battery. The solar panel is connected to the solar charge controller that is connected to the same battery. The battery is connected to the battery inverter that is connected to home loads or electric vehicles for electricity consumption. For the on-grid solution: We recommend a full parallel connection of wind turbine and solar panel unless you have a very good quality 2 MPPT inverter. The wind turbine is connected to the wind turbine charge controller which is connected to a grid inverter. The solar panel is connected to a different grid inverter to ensure maximum efficiency of the entire system. Both grid inverters are connected to the home separately for electricity usage. They're also connected to the grid via the metering device and retailer meter to feed the extra electricity back into the electrical grid network. Click here to see the detailed off-grid and on-grid system diagrams.
  • There is a vibration when my TESUP Wind Turbine rotates. Why?
    All screws, bolts, and mounting parts of the turbine system must be mounted correctly and securely during the installation. Additionally, the mounting base of the turbine must be fixed to the mounting surface properly and checked that it is fully stable. Otherwise, vibration may occur. Please check the screws and bolts on your wind turbine system at least every 6 months to make sure they are properly fastened.
  • What are the recommended minimum and maximum heights to install a TESUP Wind Turbine?
    Minimum and maximum height requirements change from country to country. But as a general direction, the distance between ground level and the lowest part of any wind turbine blade should not be less than three meters. And the highest part of the stand-alone wind turbine shouldn't exceed 11 meters. These are the average limits to follow in most countries. We highly recommend you check the specific requirements in your country. The placement of your vertical and horizontal wind turbines can have a large effect on how much power they generate. We recommend you place your TESUP Wind Turbine as high as possible, ideally on the roof of a building or on a standalone pole. Wind speed is the lowest on the ground level so making sure that the turbine is as high up as possible will maximize the rotation speed and power generation. A horizontal wind turbine should not be placed behind obstacles (like buildings or trees). If there is an obstacle, the turbine can be placed on a pole to ensure its level is much higher than the obstacle.
  • How can I reach maximum efficiency with my wind turbine?
    The amount of power that can be extracted from the wind depends on the speed of the wind and the size of the turbine blades. No wind turbine is 100% efficient (even when running at its optimum wind speed). There is friction between all the moving parts, and some power is lost at the gears or different connection parts of the system, and this is normal. You can use TESUP Power Curve Chart included in the user manual in order to calculate the true output for the average wind speeds on your site. This allows you to see the estimated power output at your local wind speed. In order to make the system operational and reach the estimated power output, TESUP Wind Turbine, TESUP Charge Controller, and TESUP selling grid inverter are all required. Additionally, you must make sure that your turbine system is installed by a professional electrician, fixed securely to the mounting surface, and adjusted according to the wind direction.
  • Why is the voltage of my wind turbine low?
    There are many reasons why the turbine may be demonstrating lower outputs than anticipated. These reasons can stem from turbulence and erroneous measurements through battery type and condition. Turbulence is the most common reason why turbines do not perform to their specification. Cable size may also affect the output. Ensure that the correct minimum and maximum cable sizes are installed. Different battery technologies, battery age, and conditions will also affect the rate at which the batteries can absorb power. Last but not least, measurement errors may occur easily while measuring the wind and power output of the turbine. Ensure that high-quality shunts are employed for accurate current readings.
  • I can't get current from my wind turbine. Why?
    The turbine may be running in an off-load state, meaning that the circuit from the turbine to the batteries is incomplete. In this situation, the turbine is free spinning and may generate higher voltages than anticipated from the turbine output cables. Check that all of the connections from the turbine through the run/stop switch and the batteries are correct. If a fuse or circuit breaker has been fitted to the turbine, ensure that this is correctly closing the circuit. Never leave the turbine running in an off-load state, as it may cause damage to the turbine during high winds.
  • Something is stopping my wind turbine; it was working well before. What might be the problem?
    There are a few reasons that might cause this issue: 1. If the wind turbine is connected to a battery, the charge controller stops the wind turbine once the battery is full to the adjusted maximum charging voltage level. 2. If two or more cables are touching each other we call it short-circuit. The short-circuit can stop the electricity flow and this might be a reason. Please control all cables and be sure they are not touching each other. 3. There are some cheap hybrid battery inverters in the market. There are battery inverters and solar charge controllers combined but these cheap hybrid charger inverters are acting as solar charge controllers at first. These devices can stop the wind turbines via the battery. 4. Limit voltage adjustment with the potentiometer may be wrong. If the led lights up, it means it is braking. If the potentiometer is set incorrectly, the turbine will brake in order not to exceed the determined voltage. 5. The switch on Charge Controller can be in position 1. 6. Our system is integrated into the end consumption point. The TESUP Charge Controller converts produced energy to heat in dangerous situations(dump-load system). But, the fuse connection prevents this. That's why customers shouldn't use a fuse connection between the wind turbine-charge controller-inverter connection.
  • I think my wind turbine is not rotating freely. What could be the reason?
    TESUP wind turbines have permanent magnet generators having strong N42 neodymium magnets with steel slots inside. These wind turbines are designed for maximum power performance. When the wind speed is over 4m/s, the turbine rotates freely by exceeding this holding torque (cogging torque).
  • I have an ATLAS 7 wind turbine which is connected to an inverter. The system is ongrid and working well, but how can I improve its efficiency?
    The ATLAS 7 wind turbine is a vertical wind turbine. It can start its rotation at 5m/s wind speed. Once it starts rotating, it can generate power even at 4m/s wind speed. On the other hand, every inverter has a different minimum DC startup input voltage, it varies from 50V to 80V for TESUP Inverters. If your wind speed is not high enough to generate the required voltage, the inverter will not start operating and won't transfer your wind turbine’s power to the electricity grid.
  • Are there any precautions I should take in very windy weather?
    Our wind turbines are very robust and durable. They operate safely in normal windy conditions. If a hurricane scale III (50–58 m/s) or above occurs, please cover wind turbine blades. If you live in a very windy location, we recommend you have a suitable cover (or an item to be used as a cover) in hand to be ready for emergencies.
  • What are the weights of TESUP Wind Turbines?
    TESUP Magnum 5 is 23 kg / 51 lbs. TESUP ATLAS 7 is 20 kg / 44 lbs. TESUP ATLAS X7 is 23 kg / 51 lbs. TESUP Master X is 9 kg / 20 lbs.
  • Are connection cables included in TESUP Wind Turbine packages?
    No, connection cables are not included because the cable size and quantity depend on the location of your wind turbine and its distance to the other components of your energy system.
  • What has changed with the new ATLAS Series? What are the differences between the old ATLAS models and the new ATLAS 7 and X7?
    Our ATLAS wind turbines have been upgraded and they are now more powerful, durable, ergonomic, and stylish than ever. WHAT IS NEW? 1. More power, more electricity and savings New ATLAS models come with a more powerful and efficient 7 kW generator. They can generate up to 168 kWh per day! NEW ATLAS models are engineered to provide better grip between the body and the blades so that when blades turn, their rotary movement (force) is transferred to the generator without loss of power. So it makes the ATLAS Wind Turbines more efficient. 2. New stylish and ergonomic design The newly enhanced body provides ATLAS wind turbines with a more modern look and better protection from external factors. Plus, the new metallic grey colour gives the products a more premium look. 3. Easier assembly ATLAS X7 has a new guiding frame for easier assembly. With this new frame, it is really easy to keep the wings in line to fit the upper flange. All you need to do is to assemble your wind turbine following each step in the product user manual. The assembly process only takes 30 minutes. 4. Better durability Now we've changed the material of the fasteners to stainless steel on both ATLAS models for better durability. 5. Customization New ATLAS X7 gives you 6- or 12-blade options to adjust the number of blades on your turbine depending on the average wind speed at your specific location.
  • What are the differences between the new HERA Wind Pro and the ATLAS Series?
    TESUP HERA Wind Pro is our most efficient and sleek vertical wind turbine with the lowest starting wind speed and the highest power generation capacity. The key differences between HERA Wind Pro and Atlas 7 & X7 are the following: 1. Lowest Starting Wind Speed Like ATLAS 7, HERA Wind Pro has the lowest starting wind speed. Its rotation starts at 4 m/s wind speed. Upon rotation, power is generated at even 3 m/s wind speed. 2. More Rapid Acceleration After rotation starts, HERA Wind Pro accelerates more rapidly versus other TESUP Wind Turbines under the same wind speeds. 3. New innovative design and more colour options HERA Wind Pro is TESUP's most innovative, compact, and premium vertical wind turbine design. It is available in 3 modern colour options: Pearl Beige, Pearl Blackberry, and Smoke Grey+Red. 4. Less Environmental Impact & Quicker Installation HERA Wind Pro has a new 2-blade shape that is produced by using less material. As a result, it is lighter, more compact, and has less environmental impact than other TESUP vertical wind turbine models. Since it has fewer blades, its installation process is shorter and takes only 15 minutes. 5. New Enhanced Body Design HERA's new body base allows easier fixing to the surface, provides better protection, and creates a cleaner look.
  • Can I use my wind turbine without a charge controller?
    No, you can't use your TESUP Wind Turbine without a TESUP Charge Controller. It is an essential part of the TESUP Wind Turbine System. It controls the wind turbine and acts as a manual emergency brake to protect your wind turbine in the case of an emergency. It is also required to convert AC (Alternating Current) to DC (Direct Current) and control the battery and inverter to prevent overcharging.
  • How many wind turbines can be connected to the TESUP Charge Controller?
    You can connect 1 TESUP Wind Turbine to each TESUP Charge Controller.
  • What is the manual switch (emergency brake) on the charge controller used for, and in what position should it be?
    The switch on the charge controller is a manual braking switch to stop the wind turbine in case of an emergency. In stormy weather, it's better to activate manual braking by turning this switch to the "1" position to protect the system. Under normal weather conditions, the switch button must be kept at the "0" position to continue producing energy.
  • What is the potentiometer (Max. Battery Charging Voltage Adjustment) on the charge controller used for?
    If there is a battery in the system, the potentiometer on the charge controller is used to adjust the maximum limit voltage. In case the maximum limit voltage is reached under very windy circumstances, the controller automatically brakes the system to avoid damage to different parts of the turbine or battery. This maximum voltage value should not exceed 18V for a 12V system, 30V for a 24V system, and 58V for a 48V system.
  • Does the voltage value on the charge controller screen indicate the voltage from the turbine?
    If the charge controller is connected to the battery, the battery voltage is shown on the screen. If the charge controller is connected to an inverter and set to "Inverter" mode, the charge controller displays the voltage from the turbine. But this screen is mainly designed to show the battery voltage. Please do not switch to "Inverter" mode when the charge controller is connected to a battery. Sometimes, the produced voltage can reach up to 220V. In this voltage range, the PCB board might get damaged. Additionally, during the storm, the charge controller must be manually adjusted up to 120V (maximum). Inverter customers can do this manual adjustment by using their charge controller in battery mode.
  • Is there a brake system on TESUP Charge Controllers?
    Yes, TESUP Charge Controller is an intelligent controller with fully automatic wind turbine protection. It has an electromagnetic braking system and a manual emergency brake button.
  • Is it possible to connect a load directly to the charge controller?
    No, it is not possible. It must be connected to a battery or a grid inverter based on your energy system type. Without the connection to a battery or a grid inverter, a charge controller will not output a steady Voltage and may never function.
  • There is no voltage generated in the system. Is it normal?
    It is not normal. All TESUP products are subject to strict quality control and operation tests before they are packed. Therefore, if your system doesn't generate any voltage, it could be due to a setup or adjustment error. Please check the following 2 points for the best product performance: 1. If the batteries are full, the charge controller will stop the wind turbine to prevent over-charging. Please turn on some electric appliances or power consumption units to ensure constant consumption from the system and that your turbine keeps rotating and generating energy. 2. If the installation is correct, the maximum charging voltage level must be adjusted via the potentiometer on the charge controller. You should rotate the potentiometer button until the led lamp on the potentiometer goes out. This value should not exceed 18V for a 12V system, 30V of this value for a 24V system, and 58V for a 48V system.
  • My charge controller is in battery mode. But it is not working or getting power. Why?
    There are two systems for braking in the battery mode; manual braking and potentiometer adjustment. In potentiometer adjustment, when the system reaches max voltage, the turbine slows down and protects the system. In cases where the wind speed increases and the generated voltage value exceeds the maximum voltage value, the potentiometer automatically transmits the incoming voltage to the resistors. When it falls below the maximum voltage value again, the energy is transferred to the batteries, rather than the resistors. If the battery is fully charged, the produced electricity will be transferred to the resistors.
  • When the charge controller is connected, my turbine brakes. Why?
    There are several reasons for braking: 1. If there is not enough load in the system, the system brakes. 2. If the manual brake button on the charge controller is in position "1", then the system might brake. 3. If the charge controller is in battery mode and the batteries are full, the system brakes. 4. Potentiometer adjustment might be wrong. If the led lights up, it means that the system is braking. 5. There might be a short circuit in the system. If two or more phase cables are in contact with each other, the system brakes. Please check this. 6. It might be a smart system and an incompatible device such as Voltronic might be used as the battery inverter. This might have burnt the generator.
  • Does the potentiometer braking option work when the Charge Controller is used in ''Inverter'' mode?
    No, the potentiometer braking option is only active in ''Battery'' mode.
  • How can I adjust the potentiometer according to my battery capacity?
    Maximum voltage value should not exceed 18V for a 12V system, 30V for a 24V system, and 58V for a 48V system. Otherwise, the card and screen may burn in the case of excessive voltage.
  • Does the Charge Controller need to be installed indoors or outdoors?
    Our recommendation is to install TESUP Charge Controller outdoors. The charge controller must be protected from direct rain, snow, and sunlight. So, the outdoor location must be selected accordingly.
  • Can I connect TESUP Charge Controller to other brands' wind turbines?
    TESUP Charge Controller works only with TESUP Wind Turbines. We don't recommend its use with other wind turbine brands. Any system failure or damage occurring due to its misuse is not under TESUP Warranty.
  • Can I learn TESUP inverters' startup voltage?
    Our Inverters' startup voltage mostly varies from 50V to 80V depending on their model and they keep operation above 50V.
  • Which inverter is the best for wind turbine connections?
    We recommend parallel connection of each wind turbine to a separate inverter. In this way, any operational problems on one wind turbine won't affect the others and the system will continue to generate energy.
  • Can I use a hybrid solar inverter with my TESUP Wind Turbine?
    We don't recommend you connect a TESUP Wind Turbine to a hybrid solar inverter. Parallel connection of every energy generation unit with a separate inverter will maximize the energy generation and avoid big system breakdowns in the case of an emergency or system failure. Technically, it is possible to connect TESUP Wind Turbine to a hybrid solar inverter if it has two different entries for both wind and solar products, but we don't recommend it to avoid any potential damage caused by this hybrid connection. Any damage to TESUP Wind Turbines occurring due to a hybrid inverter connection is not under TESUP Warranty.
  • Does TESUP Inverter support the hybrid system? Do I need a separate inverter for the solar panels?
    We recommend separate inverters for TESUP Wind Turbines and TESUP Solar Panels. TESUP inverters have 1 MPP tracker and allow a single energy generation unit connection. Every additional wind or solar energy generation unit requires a separate inverter.
