I'm reaching out to inquire about your solar products, specifically one that aligns with the SFB series. I'm interested in understanding the specifications, pricing, and availability of this particular item. Additionally, if you could provide details on bulk order discounts, lead times, and any warranties or after-sales support available, that would be greatly appreciated. I'm looking forward to your prompt response so we can explore possible collaborations. Thank you!
