I am looking for a reliable supplier for a 5kW, 48V power system designed for home installations. This system is intended to support residential energy needs efficiently, so I'm interested in understanding the features, specifications, and overall performance of your products. It would be great to know if you have options that include both inverter capabilities and energy storage solutions. Additionally, please provide information on pricing, lead times, and any bulk order discounts that might be available. I'm particularly keen to learn about warranty periods and after-sales support, as these factors are incredibly important for a smooth installation process and long-term reliability. Looking forward to your detailed response!
