Qualité de fabrication au top. Attention toutefois à l’intégration de l’écran qui n’est pas droit.
Thanks to your patience and that of a good broker like Susan Yang, I can say that the company is very much alive and active. Thank you for your work , great work , everything is going very well . I was accompanied by good advice and excellent skills.Thanks again.
We purchased a solar system from DELONG Energy , comprising a 10kwh and 5kwh, 51.2v lithium battery pack. The sales contact, SUSAN was incredible, extremely responsive, patient, and knowledgeable. She was super fast in responding to our many, many queries. The delivery was right on the nose, and everything arrived well packed and in pristine shape. I rate the transaction an overall A, and the service an even higher A+.
The Delong hybrid solar system is the most convenient and cost-efficient system I encountered in my search for the best hybrid solar system. The total system was very useful and easy to operate with so many useful features in plotting my desired setup. But most of all, I commend Miss Susan yang for being such a nice and very accommodating agent. All my doubts and worries were gone, from the product selections, billings, and freight forwarding were all organized by her.
I am very happy with the quality. everything works as it should and communicates perfectly with my Deye Inverter. the shipping was a bit delayed, but it was still ok. Mary is a super friendly and helpful seller. she was always able to help me quickly and answer all my questions. Will order more goods.
