Household energy storage systems are installed inside homes and are usually linked to rooftop photovoltaics, power grids or charging piles to provide households with a three-in-one energy management solution that “saves money, maintains power and is green”.

1. Peak shaving and valley filling

In areas with time-of-use electricity prices or tiered electricity prices, the system can charge at night/low electricity price periods and discharge during the day/peak hours, directly reducing electricity expenses.

2. Maximize self-consumption of photovoltaics

Store excess electricity from rooftop photovoltaics in batteries during the day and release it again at night or on rainy days, increasing green power utilization by 20%–40% and reducing power purchases from the grid.

3. UPS level emergency backup power

When power outages occur due to grid failures or natural disasters, millisecond-level off-grid switching can be achieved to continuously supply power to key loads such as refrigerators, lighting, networks, and charging piles.

4. Dynamic expansion and power limitation

When the household's instantaneous load exceeds the contracted power of the grid (such as when a high-power charging pile is activated), the energy storage can be instantly discharged to avoid tripping or demand penalties.

5. Intelligent energy management

Equipped with EMS/APP, it can monitor generation-storage-power consumption data in real time, automatically optimize charging and discharging strategies based on weather, electricity prices, and load forecasts, and achieve "one-click hosting."

6. Virtual Power Plant (VPP) participation

In mature markets such as Europe, the United States, and Australia, household energy storage can be aggregated into VPP to provide frequency regulation and peak shaving services to the power grid to earn additional income.

7. Green low carbon and carbon management

By storing renewable electricity, we can reduce fossil energy consumption and reduce household carbon emissions; some systems can be connected to carbon ledgers or green certificates
