I'm looking to source a vertical wind turbine with a capacity of around 500 watts, specifically designed for 12V systems. It's crucial that the turbine meets high efficiency standards and is suitable for use in varied environmental conditions. I'm interested in understanding the specifications in detail, including the materials used, dimensions, and any safety features that are part of the design. Additionally, I'd like to know about the available options for installation, maintenance support, and warranty terms. If you have any certifications or test results that authenticate performance claims, that would be greatly appreciated. Please share pricing information, lead times for production and delivery, and any bulk order discounts you might offer. Looking forward to your prompt response.
