I'm reaching out to inquire about the pricing details for a 5kW product. Could you please provide the unit cost along with any available discounts for bulk orders? It would be great to understand the different pricing tiers based on quantity, as this will help us in planning our procurement efficiently. Additionally, it would be helpful to know about the lead time for delivery, payment terms, and any warranty or after-sales support offered with the product. If you have any datasheets or additional information that highlights the specifications and features, please include that as well. Looking forward to your detailed response so we can consider moving forward.
