Terms & Conditions 

These terms and conditions were last updated on 7 January 2022. Use of our websites, sales and purchase of goods from the website are governed by our terms and conditions as set out below. 

1. Delivery Arrangements 


The company (TESUP) is responsible for the door delivery. Your order will be delivered to your door-step. Normal delivery timeframe is within three business days subject to stock availability. We will notify you by an email once the box is shipped or if your order is not available in the warehouse stock to be dispatched within this timescale. If the products are temporarily out of stock, we will contact you to provide information about the expected waiting time for shipping once they are back in stock. The company reserves the right to provide an upgraded product if the purchased goods are no longer available.

2. Guarantee 

All products come with a TESUP warranty. 2 Years free TesupCare product warranty is standard. Customers can also purchase longer-term TesupCare product warranty and refund options subject to the specific products. 

3. Your Right To Cancel or Request a Partial Refund 


After receiving a TESUP product, you have the right to request a return of the product within 5 working days. Provided the box remains unopened. The products are custom-made items which are specially designed and packed with non-reusable packaging material. These high-tech packaging chemicals and equipment can be used only once. For this reason, if the box is opened, the company can not accept the return of the product. The company controls and examines returned boxes with photo recordings. Once the order is shipped from our warehouses or factories, returning the boxes to the company is the only way for a refund. If you experience a problem with the product during operation, please submit a Support ticket. Our engineers will go through your ticket and try to find a solution; a replacement, partial refund or purchase of new spare parts. We offer replacement options for warranty-covered discounted sales.​

TESUP Companies have a goal of reaching maximum customer satisfaction. We spend effort and time making products unique and special for our consumers. Our products have got your name tags and unique serial numbers (operational test videos recorded) on them. Hence that's not possible to ship your boxes to other consumers. In case of order cancellation or refund our technicians repaint and repackage them. As expected, this is not environment-friendly. We charge a 15% cancellation fee for all order cancellations, returns and refunds. We kindly expect that you understand the outcomes of these additional manufacturing stages. 


4. Description of Goods 

Our wind turbine systems can only be used as a 'Small Wind Turbine System' (SWTS) to generate power in accordance with EN 61400-2. Our products can be used for low voltage generation purposes; voltage can be maximised to 75V with a TESUP Charge Controller. Our wind turbines should operate with a charge controller at all times. We are constantly improving our technology; our latest wind turbines can generate more than 100 volts during high winds, some products even at 10 m/s wind speed. The TESUP Charge Controller can adjust and limit the output voltage level between 0 to 75 volts. If the inverter option is selected using the button on the TESUP charge controller, there is no maximum voltage limitation. Stickers warning of electrical danger are on our products.
