Dyness Knowledge | Selection of energy storage batteries in home energy storage system design

In today's era of increasing emphasis on environmental protection and energy conservation, especially in overseas countries, the interference of external factors in recent years has caused the cost of civilian electricity bills to increase year by year. Installing home energy storage systems can ensure the stability of electricity consumption and reduce electricity bills. Become the first choice for local residents. Through energy storage systems, households can better utilize renewable energy sources, such as solar and wind energy, to meet household electricity needs. Battery selection in an energy storage system is a crucial part. Let’s take a look at the principles of battery selection in a home energy storage system.

First of all, capacity is one of the key factors in selecting energy storage batteries. The home's electricity needs and the design capacity of the energy storage system will determine the battery capacity selection. Generally speaking, the higher the capacity, the stronger the battery life, which can support the family's electricity consumption for a longer period of time. The battery capacity of the home energy storage system can be determined based on the household electricity bill. Based on the electricity bill, the family's basic power consumption and electricity usage habits can be determined, and then a battery of appropriate capacity can be selected accordingly. Secondly, if the user not only wants to use the battery as daily power supply, but also wants to use it as an emergency backup power supply during a power outage, he or she can refer to the electricity usage in the electricity bill. After preliminary calculation of the average daily power consumption and the number of hours of power required from the energy storage battery during a power outage, the battery capacity can be determined.

Secondly, cycle life is also a very important factor. The cycle life of an energy storage battery is an important indicator of its service life. Energy storage batteries with a longer cycle life need to be selected to ensure long-lasting and stable operation of the system. However, it is important to note that cycle life is not the only indicator of battery life. The service life of the battery is also affected by factors such as charge and discharge rate, temperature, and depth of discharge.

In addition, charging and discharging efficiency are also factors that need to be considered. Choosing a battery with higher efficiency can improve the energy utilization of the system and reduce energy waste.

Of course, security is also very important. Choose a battery with reliable safety performance to ensure that no safety accidents occur during system operation.

Finally, cost is also a factor to consider. Choose a battery with reasonable cost, such as a basic battery module or a battery pack that is easy to install, saves space and can be wall-mounted. Or it is an All-in-one system that is similar to home appliances and has a more refined and modern appearance. Batteries are designed at various cost and price points to meet the needs of different home users to ensure the return on investment of the entire energy storage system.

When selecting batteries in a home energy storage system, you need to consider the above factors comprehensively to choose the battery type that best suits your home needs, thereby contributing to home energy conservation, environmental protection, and energy utilization.
