I'm looking to purchase a 5 kilowatt unit and would like to get some detailed information regarding the pricing and any available options. It would be great if you could provide me with a breakdown of costs, including any potential bulk discounts or shipping fees. Additionally, I'm interested in understanding the specifications that come with the unit, including warranty details and delivery timelines. If there are different models or variations, please include that information as well. This will help me in making a more informed decision. Thank you!
