荷兰采购需求：控制器逆变器、发电机、水平风力涡轮机、太阳能电池板、垂直风力涡轮机、风力涡轮机玩具

We are interested in acquiring a vertical turbine with a power rating of either 5 kW or 10 kW. This unit needs to be installed on the roof of our building, so it's crucial that it operates smoothly without causing vibrations. Our aim is to ensure that the installation won't disrupt the environment or cause any structural issues. Could you provide guidance on the specifications and options available for such turbines? Additionally, we plan to facilitate the import through our supplier located in the Xiamen area, so any details regarding shipping and compatibility would be greatly appreciated. Looking forward to your advice!
