Household energy storage systems, usually combined with home photovoltaic power stations to form a "photovoltaic + energy storage" system, have a core working principle of the cycle of "charging - storage - discharging".

1. Charging stage:

Photovoltaic charging: During the day, photovoltaic panels convert solar energy into direct current. Part of it is used by households, and the excess is converted into alternating current through energy storage inverters to power household appliances. At the same time, the remaining electricity is stored in energy storage batteries.

Grid charging: During the off-peak electricity price period at night, the system automatically draws power from the grid to charge the battery, achieving "low purchase".

2. Storage stage: Electrical energy is safely stored in dedicated lithium batteries in the form of chemical energy and is always on standby.

3. Discharge stage:

Nighttime/cloudy power supply: When photovoltaic power generation is insufficient, the system automatically switches to battery power supply, prioritizing the use of stored green electricity.

Peak electricity consumption: During the peak electricity price period of the power grid, the system stops purchasing electricity from the grid and instead uses batteries for power supply, achieving "high electricity consumption" and saving electricity bills.

Emergency backup: When the power grid is cut off, the system can instantly switch (UPS function) to supply power to critical loads (such as lighting, refrigerators, routers), ensuring the basic electricity needs of the household.

The advantages of Household energy storage systems

1. Increase the self-consumption rate of photovoltaic power: By storing excess photovoltaic power for self-use instead of selling it cheaply to the power grid, the utilization rate of green energy is greatly enhanced. Typically, the self-consumption rate of household photovoltaic power can be raised from 30% to over 80%.

2. Save on electricity bills: By taking advantage of the "peak-valley price difference", charge when electricity prices are low and discharge when they are high, effectively reducing the overall electricity cost for the household.

3. Ensure emergency power supply: Provide emergency backup power during power outages due to grid failures to enhance the reliability and sense of security of household electricity usage.

4. Intelligent and convenient: The system can intelligently manage energy. Users can monitor power generation, consumption and storage in real time through the mobile phone APP and set the mode.

5. Green and environmentally friendly: Promote the consumption of solar energy, reduce reliance on fossil fuels, and lower the carbon footprint of households.

Summary: Household energy storage systems is like a "green power bank" for a family. By intelligently dispatching electricity, it achieves efficient, economic and reliable energy utilization, and is an important component of modern smart homes and zero-carbon living.
