新加坡采购需求：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

I'm looking for a complete setup for both on-grid and off-grid (battery-less) solutions tailored for my factory, with a load requirement of around 5KW. Please provide a detailed proposal that includes all necessary components, technical specifications, and pricing. It would be great if you could highlight any key features and benefits of your systems in the proposal. I'm particularly interested in efficiency, reliability, and ease of installation, so any insights on those aspects would be appreciated as well. Looking forward to your response!
