Welcome to TESUP Customer Support

Every country has different policies and schemes regarding energy export and selling to the grid. Rules change from government to government, so we recommend you investigate your local country's requirements in detail.

As a general direction, it is possible and supported to sell surplus power generated from your wind turbines and solar panels to the national grid in many countries in the World. You should register under the relevant energy export scheme through your energy supplier in your country. After the registration, you'll get paid for every unit of electricity you feed back to the grid.

There are multiple factors to be taken into consideration for cable selection.

The quality of the insulation affects the rating of the cable. PVC insulated cable with a temperature rating of 75°C is typically used and recommended. Cable insulated with butyl rubber has a higher temperature rating and can therefore carry higher currents.

Additionally, poorly made and corroded connections can introduce very high resistances into a circuit and are probably the most frequent cause of poor system performance.

Tinned cable is the best as this offers superior corrosion resistance to untinned copper wire, particularly in the marine environment.

When considering which cable size to use, we recommend you assess the total length of the cable run in meters. Please remember to include the height of any mounting tower or tube, then multiply this by two, which gives the total circuit length.

The section of the cables can be decided depending on the number of units in the system and their distance from each other.

For the best results, we recommend you get installation support from an electrical engineer or electrician who is an expert in this area.

The first step to assess the performance of your wind turbine system is to check the power curve for that particular wind turbine (Wind speed versus electrical power generated). This curve shows how efficiently the turbine converts the wind energy into electricity.

The actual performance of your system will be affected by local wind conditions, nearby obstructions, power demand profiles, and a range of other factors, such as connections and the quality of the materials used. So power curve on its own might not match your exact power generation, but the values should be reasonably close if everything in the system works well.

In real life, there will be multiple factors affecting the power generation of your wind turbine such as its height, connection quality, cables used, and the efficiency of other system components. But in order to make an estimated calculation for the ideal conditions, you can check the power curve of the TESUP Wind Turbine. You should take a few things into consideration for the estimated yearly power generation. These are the average wind speed for the selected location, hours of wind per day, wind turbine's power generation capacity at the location's wind speed, number of days that the wind turbine is expected to operate, and any additional factors that might affect the efficiency of the system and can be used as a multiplier.

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.

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.

Both models are very robust, compact, and durable yet lightweight.

V7 Low Wind 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.

V7 High Wind 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 V7 Low Wind.

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.

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.

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.

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.

TESUP  V7 Moderate Wind  is our most efficient and sleek vertical wind turbine with the lowest starting wind speed and the highest power generation capacity.

The key differences among V7 Moderate Wind and V7 High Wind and V7 Low Wind are the following:

1. Lowest Starting Wind Speed

Like V7 Low Wind,  V7 Moderate Wind 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,  V7 Moderate Wind accelerates more rapidly versus other TESUP Wind Turbines under the same wind speeds.

3. New innovative design:

 V7 Moderate Wind is TESUP's most innovative, compact, and premium vertical wind turbine design.

4. Less Environmental Impact & Quicker Installation

V7 Moderate Wind 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

V7 Moderate Wind's new body base allows easier fixing to the surface, provides better protection, and creates a cleaner look.

TESUP Flexible Solar Panels can be installed and fixed on the selected surface via gluing, double-sided adhesive tape, screwing, or riveting. If adhesive tape or gluing is used, you must ensure that the selected adhesive tape or glue is suitable for outdoor applications with a wide temperature range and UV protection. The surface must be very clean and dry to ensure strong attachment.

The double-sided adhesive tape makes a strong immediate bond with the support material and does not allow repositioning. You must not try to move the panel after the adhesive tape application, even if it is only partially attached. Otherwise, you may seriously damage the solar cells. If you prefer gluing, you must leave it for at least 24 hours at normal room temperature after the application to achieve full adhesive strength. If you plan to install your solar panel in a vertical direction that requires high holding power, screwing would be a safer and stronger option for installation.

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.
