Backdrop ：1. To involve more people in energy strategy, reduce carbon emissions, protect the environment, and allow leasing users and those with poor economic conditions to use clean energy. 2. Methods and approaches: Store excess solar energy generated during the day and use it at night to reduce the overall electricity costs of the household. 3. The increase in carbon emissions has led to severe environmental pollution.The support of new energy policies.The rise in electricity prices has caused a surge in electricity expenses, putting economic pressure on renters and those with poor financial conditions.Practicability：1. The battery pack adopts a user-friendly stackable design, with no need for wiring between battery packs, and only one cable required for connection with the main unit, maximizing space utilization. 2. The product adopts an integrated die-casting process, with high strength, a lifespan of 10 years, and IP65 waterproof hardware design, ensuring a reasonable payback period for users. 3. The product has dual MPPT inputs, with a rated power of 800W and can be connected to solar panels with a maximum power of around 900W, constantly capturing the highest efficiency of the solar panels. The power supplied to the household can be adjusted, ranging from 100-1200W, adapting to various different microinverters with different power requirements. Excess solar energy will be stored in the battery when the household demand is low. 4. The stored energy in the battery can be supplied to the household when there is no sunlight, helping users reduce electricity costs. The SmartPVHub allows up to 4 AB1000 to be connected, with a capacity that can be expanded from 960Wh-3840Wh, suitable for different household needs.Design aesthetics：1.SolarFlow energy storage system adopts the concept of modular design, adopts the humanized stackable design, and is matched with the simple and technological sense of Jingtiao elements to provide a better product experience both visually and operatively. 2. The product adopts integrated die-casting process with strong appearance integrityCultural：1.As a plug-and-play grid-connected solar system, SolarFlow does not require users to queue for professional electricians, and adheres to sustainable development, providing an energy optimization solution for more green energy enthusiasts and environmentalists, which is of great significance for social sustainable development.Safe and easy to use：1. The product adopts the process of integrated pressure, metal body, strong and durable, reduces the frequency of electronic waste, and has avoided the pollution of plastic to the environment. The waterproof level is IP65, and the product can be guaranteed for 10 years, contributing to the long-term energy independence of users. 2. The battery pack adopts humanized stackable design, the connection between the battery pack does not require cables, and the connection between the host requires only one cable, which is simple to connect and maximize the use of space.
