Dyness Omdömen 

I think the service is excellent. I got a new upgraded tower from Dyness. Installed by a very nice and friendly guy. I recommend everyone a Dyness product.

Batterie verliert auf einmal zwischen 25-50% der Kapazität und das obwohl kein Strombezug stattfindet. Support leider nicht vorhanden warte seit mehr als einem Monat auf eine Antwort. Kann ich nicht weiterempfehlen. Lieber Finger weg davon

This is an update on my previous review on Dyness's technical support and after-sales service.
Having been mistakenly supplied with a different model of battery (instead of more of the original, which is what I ordered) to increase my domestic solar bank, I sent literally dozens of emails - yes, over twenty! - to Dyness asking for technical support on how to combine them, as the digital interface sockets on the two models are labelled differently. I was particularly concerned because two other retailers (not my supplier) have stated very clearly that the two models (DL5.0C and DL5.0C Pro) are not compatible and cannot be combined. As I received no response to my initial enquiries, I copied the emails to all of Dyness's English language support departments and their sales departments in the UK, Europe and Australia. After several weeks, I still had no response, in spite of eventually re-sending the emails daily, so I decided to return the batteries as non-conforming with the contract. I had originally collected them from Lyon while visiting family. However, the supplier refused to accept a return to Lyon, and insisted that I should take them to an address near Montpellier. This was a round trip of 2,140kM and necessitated an overnight stay nearby. I needed to be present in person at the handover in order to confirm that the boxes had not been opened or damaged and that the goods were undamaged. The trip cost me over €200 in diesel alone (although that was still much cheaper than using a courier to transport 350Kg of hazardous goods to the opposite side of France). Two weeks later I eventually received the refund for the cost of the batteries, but received nothing towards the cost of returning them.
While I have been perfectly satisfied with the performance of the batteries themselves - we have now gone off-grid with our solar panels and battery bank - in my experience, Dyness's after-sales service and technical support is simply non-existent, as every email has been ignored, even though on their accompanying documentation they promise 24/7 support. In view of this, I will be going elsewhere in future.

Great service from start to finish! The product is brilliant quality and exactly what I was looking for. Really happy with my purchase and would definitely recommend!

Been using Dyness products for a while now and I’m seeing exceptional feedback a great product

Fijn merk betrouwbaar en bij garantie zijn ze tenminste niet op vakantie. Heb nu 2 klanten gehad in 3 jaar tijd waarbij het vervangen moest worden. Werd allemaal binnen een week geregeld!

Top!
