Working Principle
Electricity prices and grid loads undergo periodic changes throughout the day: during valley periods (late night/early morning), electricity demand is low, prices are affordable, and the grid has surplus capacity. The system stores energy by charging via grid power or optional photovoltaic modules. During peak periods (e.g., evening peak usage hours), electricity prices surge and grid loads become strained, so the system automatically switches to using stored energy to power homes or businesses. Through the model of “storing electricity during valleys and using it during peaks,” it avoids expensive peak-hour electricity consumption and fully utilizes low-cost surplus energy during valleys, achieving optimized electricity usage.
Core Advantages
Cost Savings: Charge at low prices during valley periods and use stored energy during peaks to significantly reduce electricity bills. Suitable for various scenarios including households, small businesses, hotels, and shops.
Grid Stability: When adopted by a large number of users, it eases grid pressure during peak hours, reduces the risk of power outages and voltage fluctuations, and enhances the stability of the entire energy system through demand-side response.
Improved Energy Efficiency: When paired with photovoltaic modules, it maximizes the use of renewable energy by storing excess solar power generated during the day for nighttime use, reducing reliance on fossil fuels.
Reliable Power Supply: Acts as a backup power source during sudden outages, ensuring the continuous operation of critical equipment such as refrigerators, routers, and medical devices—while optimizing energy costs.
