Why should solar panels be equipped with LiFePO4 power station?

LiFePO4 power station

LiFePO4 power station is indispensable when using solar panels. The solar panels charge LiFePO4 power station through the controller, and the LiFePO4 power station uses off-grid inverter to invert the output for users to use. LiFePO4 battery components are commonly used in power stations, so they are called LiFePO4 power station.

Why should solar panels be equipped with LiFePO4 power station? When using solar panels, LiFePO4 battery power station accounts for the largest proportion of time. The cost is much higher than that of solar panels, and the lifespan is much shorter than that of components. However, when using solar panels, LiFePO4 power station must be used to store electricity. . Because solar panels do not have the functions of storing power and adjusting the output power of solar panels, it is necessary to use LiFePO4 power station to ensure the stability of the system power, and to ensure the power consumption of the load at night or on cloudy and rainy days.

Three reasons why solar panels are equipped with LiFePO4 power station
1. The power generation time of the solar panel and the load power time are not necessarily synchronized. Solar panels generate electricity, the input is the component, which is used for generating electricity, and the output is connected to the load. Solar panels generate electricity during the day, and only when there is sunlight, the power is usually highest at noon, but at noon, the demand for electricity is not high. Many households use off-grid power stations to use electricity at night. What about the electricity generated during the day? To store energy first, this power storage device is LiFePO4 power station. Wait for the peak electricity consumption, such as 7 or 8 o'clock in the evening, and then use the LiFePO4 power station to release the electricity.

2. Solar panel power generation and load power are not necessarily the same. Solar panel power generation is affected by the radiance and is not very stable, and the load is not stable, such as air conditioners and refrigerators. The board is directly loaded, which will cause the system to be unstable and the voltage will fluctuate. LiFePO4 battery is a power balance device. When the photovoltaic power is greater than the load power, the controller sends the excess energy to the LiFePO4 power station for storage. When the power generated by the solar panel cannot meet the load needs, the controller then uses the power of the LiFePO4 power station. Sent to the load.

3. The cost of off-grid system is high. The off-grid system consists of solar panels, solar controllers, inverters, LiFePO4 power stations, loads, etc. Compared with the grid-connected system, there are more batteries, which account for 30-40% of the cost of the power generation system, which is almost the same as the components. Moreover, the service life of ordinary power stations is not long. Lead-acid batteries are generally 3-5 years, and lithium batteries are generally 8-10 years, and they need to be replaced afterwards.

The new LiFePO4 battery power station, as the energy storage device of the photovoltaic system, can increase the energy storage efficiency to 95%, which can greatly reduce the cost of solar power generation. LiFePO4 battery has 95% energy efficiency, while the current commonly used lead-acid battery is only about 80%. The LiFePO4 battery is lighter in weight and has a longer service life than lead-acid batteries. The number of charging and discharging can reach at least 2000 cycles, which means that they do not need to be replaced frequently.

At present, more and more LiFePO4 batteries are used for photovoltaic power storage. With technological breakthroughs, the market share of LiFePO4 power stations is gradually increasing in photovoltaic off-grid systems. This is a new application trend. In addition, LiFePO4 power station is also an important partner for portable solar panels. E.g:

When you use ITEHIL solar panel, you use a power station composed of lithium battery components. The transmission time is long and it takes a long time to fully charge the power station, because Lithium batteries cannot be discharged at high currents. If you use the LiFePO4 power station in the ITEHIL power station series, the transmission time is short, and it can be fully charged in about two hours, because the LiFePO4 battery can discharge at the maximum current.

Summary: In recent years, the proportion of newly installed capacity of LiFePO4 battery power station in various energy storage systems has gradually increased. According to the application status and battery characteristics of energy storage power stations in various countries, it is recommended that the power station battery selection is mainly LiFePO4 battery.
