What is home battery storage?
The energy storage battery is mainly used to store electric energy from solar energy, wind power, or the local power grid. It is mainly used to store electric energy and is often used as a backup power supply for families, businesses, and farms. In recent years, with the continuous development of solar energy technology, energy storage batteries can also achieve energy independence for houses.
Do I need a permit to buy home battery storage?
Yes, in most cities and regions, you need a license to install energy storage batteries in your home. For more information, please consult the local relevant departments.
How does the household energy storage system work?
Home energy storage systems obtain electricity through solar panels or connected to the grid. When connecting the household load and the energy storage system at the same time, the solar energy or power grid will give priority to supplying power to the household load, and the energy storage system will be charged only when there is excess power.
When a power failure occurs in the home, the energy storage system will immediately identify when the power supply is interrupted, and automatically change the switch to use the energy storage battery to power the home without manual operation.

How long will a home battery storage last?
The introduction of energy storage batteries has attracted a large number of homeowners. They may all be troubled by this problem when choosing the first energy storage battery. However, the battery life of energy storage battery involves many factors: battery capacity, battery type, use mode, the number of connected appliances, and the power of appliances, etc.
Calculated as a 5 kWh storage battery:
The 400W refrigerator can last 12.5 hours
A 10W bulb can last for 500 hours
Watching TV can play continuously for about 5 hours
Indoor air conditioning cooling 6.25 hours
Equipping a home with a solar energy storage battery can ensure that some important essential appliances can keep running in case of power failure. For example, the food in the refrigerator can be kept fresh, and the mobile phone can be kept fully charged all the time.
