It's a complete scam, fronted by nice website that seduces you

I placed an order, then nothing. All you get is emails stating delay, no response to WhatsApp messages or email.

I then saw £400 off offer, to find that the website had changed, and now, I have no way of seeing my online order. They have removed my email from their website ( and reinvented themselves) and have removed all their contact details. All the tell-tell signs of a complete scam.

Don't waste your time.

Thanks for your response dated 7th jan 2.5 months after my order and numerous emails and what apps messages, however as per my original post ( which clearly you have not read ). you have deleted my access, so I cant raise a in website query , and emailsget no responses . So I look forward to my refund

Atlas 7 is pointless gave tesup the benefit of the doubt as most complaints were the delivery! well delivery took ages. but it then arrived looking amazing and it spins but it doesn't produce constant power so by the time the inverter kicks in wind drops and the inverter goes off and the cycle starts again! Now i am 400m from the beach and the highest house with clear uninterrupted wind from any direction and it still doesn't work. i think i have a possible solution but need to work out a step up transformer between the charge controller and the inverter but I'm getting no help from tesup! so please don't buy!!! you have been fully warned!

Turbine disintegrated at wind speed of 10,5m/s

I had been waiting for the turbine for months, and other months for the inverter. I ordered a 7kW set, but got a 1.5kW inverter, they said that there is power loss in cables which is why it's 1,5 kW (5,5 kW loss in a 10m long cable :-) ). Yesterday at wind speed 10,5m/s 30km/h 20ml/h turbine disintegrated.
I'm going to take them to the court. If you want to join, I'll be happy to make it a class case (joint lawsuit).

Na turbinę czekałem kilka miesięcy, kolejne kilka na inwerter. Zamówiłem zestaw 7kW, dotarł inwerter 1,5kW bo jak napisali są straty na kablach (5,5kW :-) ).
Wczoraj przy wietrze 10,5m/s wirnik się rozleciał.
Zamierzam wytoczyć im sprawę sądową, jeśli ktoś ma ochotę się dołączyć to zapraszam do kontaktu.

TESUP does not communicate regarding manufacturing defect for Hera Wind Turbine

On the 27 July 2023 I ordered a Hera Wind Turbine, order number 10078 via the tesup.ie website.

It arrived on the 31st October 2023 with a manufacturing defect as described below. I communicated this issue to TESUP on the 31st October 2023. Their last reply to me about the matter was on the 2 November 2023. Since then up until today, the 23rd November 2023 I have had ZERO REPLY FROM TESUP despite trying to communicate with them several times using various methods such as: emails to 3 TESUP staff, messages via the TESUP messaging app on my computer and on my Android phone, messages to 2 TESUP staff on Google Chat and lastly but submitting a ticket via the TESUP app on my Android phone.

A guarantee is meaningless if the seller stops communicating with the customer. TESUP used to offer a paid one to one consultation that one could book on their website. I can't find this option on their website anymore. So for me it has not been possible to have any meaningful interaction with them to resolve my issue and they simply don't reply within any reasonable period of time.

Below is the text of the email I sent to TESUP on the 15 November 2023 without any reply to date (23rd November 2023):

Dear TESUP

I have written several messages to you via the TESUP messaging app on my computer with no reply from you. I also tried to raise a support ticket yesterday via the application on my phone. I would really appreciate some reply after nearly two weeks of waiting. I know you don't like people communicating to you via different platforms but I have had no response from you via the messaging app on my computer.

When I received my Hera Wind Turbine on the 31st October 2023, I immediately wrote to you that day via the messaging application on my computer to notify you about the manufacturing defect.

Two bolts are meant to be screwed into the central rod at the top of the turbine. The bolt holes should be machined 180 degrees opposite each other to enable both bolts to be screwed in from opposite ends. The alignment of the bolt holes on my central rod are way off enabling only one bolt to be screwed in.

My suggested remedy was to send me another central rod with the two top bolt holes correctly machined 180 degrees opposite each other.

TESUP replied to me on the 2 November 2023 via the TESUP messaging app on my computer saying that and I quote:

"Hello Nigel,
Thank you for bringing the manufacturing defect to our attention. We take this matter seriously, and I want to assure you that our technical department will get in touch with you shortly to address all the issues you've raised. Your concerns are important to us, and we are committed to resolving this matter to your satisfaction. Best regards, xxxxx"

Another TESUP staff member also replied to me on the same day and I quote:
"Hello Nigel, Thank you for reaching out! This is xxxxx from TESUP. I am an engineer and will be happy to solve your concern
I will personally analyze your system and open a warranty claim for you
It might take a 3-4 days. Thank you for your patience"

I sent pictures via the TESUP computer messaging app. I have attached those same pictures to this email. One of the pictures shows a screw in the bolt hole and the other picture taken from the other side of the central rod shows a bolt hole but without the recess into which the bolt can be screwed. A replacement central rod correctly machined and sent to me would be the simple solution. Please acknowledge the problem and my proposed solution.

I would really appreciate some reply to my predicament and I would like to know what you intend to do regarding the manufacturing defect.

Sincerely
Nigel Giddey

PS: It is noteworthy that as of 23 Nov 2023 TESUP no longer has the Hera Wind Turbine for sale on their website.

I wonder why?

TESUP FRAUD

I ordered an ATLAS X7 wind turbine (attached) through a TESUP website which promised delivery within approximately 3 days. Since 2023.05.23 nothing has been delivered, neither do they offer any tel number nor email address as a contact.

Querying the delivery through WhatsApp/ Tesup website, Tesup responds with a standard explanation that they are seeing to the query and will inform me soonest (without any further notice).

After waiting months from my order the turbine finally arrived damaged! I’ve emailed the customer service team and have received an AI response where they couldn’t event be bothered to fill in all the gaps for them to insert relevant text leaving bracketed text stating “insert company name here”.

Didn’t read up on the reviews below and hope that they have improved their customer service and turned things round or I’ll be going to my bank for their payment protection to recover the costs of the purchase for this inoperable product.

Such a shame as with the climate crisis there is much hope for this kind of technology to succeed. TESUP fall very short of the mark so far and need to take a long hard look at their customer service. Please resolve my issues and I’ll happily update my review accordingly.

This is a total SCAM company. Did not receive my order and after requesting a refund they kept replying by email for 2 months saying "your refund is being processed and is expected due to next week". $2000 lost, do not buy and stay as far as possible from their website where they even deleted my account.

A Requiem for my TESUP ATLAS 4

I know that I in my last review said that I would not write another review of my TESUP Atlas 4 but as it has now sung its swansong, the blades have disintegrated, I feel it is right to have closure. All my earlier reviews listed so many issues from the 5th September, 2022, the day of ordering my turbine. As you all know it never generated a watt yet I kept it aloft and rotating. It symbolised a hope. Yesterday morning in a gust of 22m/second, well within its rotational limits according to TESUP, the lower cross-sectional arms fractured placing full force on the shorter upper arms which remained in place as the metal blades ripped themselves free, (x3), and winged off into the countryside.
Phew! What a relief! No more nights worrying about anymore problems. Nothing more to go wrong.
I have advanced my claim for compensation through HM county courts. (Online civil money claims) TESUP have not disputed my claim and the courts have awarded me damages and are now commencing enforcement. To all of you who have been scammed by TESUP this is the way forward to see this company made to pay compensation, and, if necessary, cease trading. It takes a month for the courts to make their decision and there is a following month in which TESUP can appeal the ruling though you can request enforcement at any time during these 30 days. £115 for the initial ruling and £83 for the enforcement which is all recoverable in the settlement.
Happy litigation!!! Stick to the PV panels and the batteries and you will be smiling.

ATLAS 7 Doesn't generate enough to start the inverter

ATLAS 7 - It took 3 months for my goods to arrive, eventually I had to buy a separate inverter, but as this didn't work with the turbine, I ordered one from TESUP that should work with the turbine I had purchased. That took another month to arrive. You have to pay up front then wait for ages, send reminders by email, (which take a week to be answered) because you cannot speak to anyone. Got it all installed BUT they advertise that the Turbine generates at 6 - 7 mph wind speed, but the inverter doesn't seem to kick in until at least 50 Volts is reached and this seems to be 20mph wind speed (which I got during Storm Ciaran). Now they say that there is not an inverter on the market that starts at a lower voltage. So why are they selling something saying it starts to generate at 6 - 7 mph when it needs about 20pmh to operate the inverter. Their answer is to move the Turbine to a higher position - but it is sold as a HOME Wind Turbine

TESUP SCAM

his is by far the worst company I have ever done business with. My Windmail is not working at all, delivery was incomplete (missing all bolts to mount the blades together), One blade is already broken while i gave it a spin to make it start (unsuccessfully).
Another blade is just bend because of the sun....
I ordered in August a new set of blades, had to pay upfront and still did not receive even a delivery date, I received one mail after an inquiry in September, but since nothing anymore, wrote several e-mails but no rsponse at all. I think it is a big SCAM

Do not buy from this company

Do not buy from this company! They will take your money but will not provide you with anything useful. I ordered the AtlasX in Sep 2022 and I still cannot use it as I am still waiting for the inverter.

They don’t communicate for months and then tell you that they understand and want to assist but then don’t do anything.

They are fraudulent. The don’t make their own products they just resell others. Go buy elsewhere

Do not buy from Tesup

On the website, delivery is claimed at 3 to 5 days. A week after ordering I received an email saying delivery would be delayed and I would be sent an update when delivery was imminent. No timescales referred to. Two weeks after I email/chased for further information, no response. A week later I cancelled the order using a support ticket on the app and have heard nothing since. There is no way to talk to this company and they ignore all communications. On reflection, the way I was not offered the opportunity to pay by credit card should have rung bells. Seeing other reviews it appears this company is a sham, making unrealistic claims for products they only occasionally deliver. The only phone number published for a warehouse in UK, doesn’t answer. All reputable companies selling in UK have properly manned customer service phone lines and at the very least live chat. Beware of this company. Note: this is still unresolved and I have heard nothing back and have not had any money back (or product I no longer want).

Worst customer service ever.

This is one of the worst companies I have ever worked with. The communication is terrible. They do not even read emails, they reply saying “rest assure we are giving you the best service” well I waited 6 months for a product that was “in stock” to arrive. They sent the wrong one and didn’t send the inverter. I can’t get them to even answer a simple question. Don’t bother, you will just get frustrated.

It broke down after the first proper windy weather and in spite of numerous communications via different platforms for the last 6 months, I have received no replacement or refund which I am entitled to as the product is still within warranty.

I can't find anything good to say about TESUP. They sell hard but don't deliver. I'm down €1,600 for merchandise they couldn't supply and am still waiting for a refund, (minus a 15% admin charge), it'll probably go to court.
My advice, be cautious when shopping online, and NEVER buy from TESUP.
