7. Solar energy storage application cases

Home energy storage: Reduce electricity bills and provide backup power.

Commercial energy storage: Reduce operating costs and support sustainable development.

Industrial energy storage: Used for grid peak regulation, emergency power supply and renewable energy consumption.

Solar energy storage products are an important tool to promote the use of clean energy. With technological progress and cost reduction, their application scope continues to expand. Choosing suitable energy storage products requires comprehensive consideration based on specific needs, budgets and scenarios.

At a time when sustainable energy and smart life are attracting much attention, home energy storage systems have become a key part of home energy management. Home energy storage systems of different powers, such as 5KW, 10KW, and 15KW, can meet the differentiated electricity needs of various families. 1. Working principle

Home energy storage systems mainly use photovoltaic panels to convert solar energy into electrical energy. Taking the daytime as an example, the electricity generated by photovoltaic panels is used for household appliances first. If there is excess electricity, it is stored in the battery. At night or on cloudy days, the system will automatically switch to battery power mode. When a power outage occurs, it can quickly serve as an emergency power supply to provide uninterrupted power for key loads such as refrigerators and lighting, ensure the normal operation of family life, and reduce the interference caused by power outages.

2. Market demand

Guarantee in unstable power grid areas: In remote areas or places where the power grid transformation is slow, power fluctuations and interruptions occur from time to time. At this time, the home energy storage system can effectively deal with such problems and ensure the stability of household electricity. For example, some mountainous villages often face unstable voltage and frequent power outages. After installing a home energy storage system, the reliability of electricity can be greatly improved.

Natural disaster emergency support: When natural disasters such as typhoons and earthquakes strike and cause power outages, the home energy storage system can provide the family with the key power needed for basic life to maintain the operation of lighting, communications and necessary electrical appliances. In some coastal areas hit by typhoons, the energy storage systems in residents' homes charge mobile phones during power outages to ensure smooth communication with the outside world, and at the same time power lighting fixtures for convenient life.

Independent power supply in off-grid areas: For places far away from conventional power grids such as remote islands and mountainous areas, the acquisition cost of traditional power sources is high and pollution is relatively large. The combination of home energy storage systems and photovoltaic systems can build a clean and efficient independent power supply system. For example, residents on some remote islands rely on home energy storage systems and photovoltaic panels to achieve self-sufficiency in electricity consumption and get rid of dependence on traditional power grids.

Energy-saving and cost reduction for households: With the help of the peak-valley electricity price difference, the home energy storage system can charge at low electricity prices and discharge at peak times, reducing household electricity costs and achieving efficient energy utilization and economic management. In some cities that implement peak-valley electricity prices, residents use energy storage systems to charge at low prices at night and use stored electricity during peak electricity consumption during the day, significantly reducing monthly electricity bills.

III. Product Recommendation

5KW Home Energy Storage System: Some brands of 5KW home energy storage systems use high-performance lithium iron phosphate batteries (LFP) as the power core. This battery has the advantages of stable operation, safety and reliability. Its inverter and battery are integrated into a small size and easy to install. It is suitable for small and medium-sized households and can meet daily basic electricity needs, such as the normal operation of lighting, televisions, refrigerators and other electrical appliances. At the same time, the system can be flexibly expanded. If the demand for household electricity increases in the later period, the energy storage capacity can be increased by adding battery modules.

10KW Home Energy Storage System: The 10KW home energy storage system has relatively large power and can meet the simultaneous use of more electrical appliances in medium and above households. For example, in addition to basic household appliances, it can also drive high-power appliances such as air conditioners and electric water heaters. Some products use stacked battery structure, which not only simplifies the installation process, but also has good scalability. There are generally multiple options for battery capacity, such as 10kWh, 15kWh, etc. Users can configure it according to their own household electricity habits and needs. In case of power outage, it can provide a long period of stable power supply for the family.

15KW home energy storage system: The 15KW home energy storage system is a high-power product, suitable for large villas or families with complex power demand and high power consumption. This type of system often has a stronger power supply capacity and can easily cope with the situation where many high-power electrical appliances in the home are running at the same time, such as multiple air conditioners, high-power kitchen appliances, etc. In terms of energy storage capacity, it is usually equipped with a larger capacity battery to store more electricity to ensure long-term power supply. Moreover, it has a high degree of intelligence and can be remotely monitored and managed through mobile phone APP, etc., so that users can understand the operating status and power usage of the system at any time.

Home energy storage systems of different powers have their own characteristics. When choosing, users need to comprehensively consider factors such as the actual power demand of the family, the house area, the budget, and the future power consumption plan, and select the energy storage system that best suits their family, moving towards a new era of green, intelligent, and stable energy for the family, and enjoying the convenience and comfort brought by efficient energy management.
