I'm looking for a reliable power solution for a single-family home. Specifically, I need to understand what options you offer that can meet the energy needs of an average household, ensuring both efficiency and safety. It would be great if you could provide me with some details on the different solutions available, such as installation types, energy output, and any additional features that might enhance performance. Additionally, I would like to get an estimated price range for your products and services. It's important for me to understand the total costs involved, including any installation fees or ongoing maintenance. If you could also share information on warranty options and after-sales support, that would be very helpful in making an informed decision. Looking forward to your prompt response!
