Solar power generation systems have high cost, low conversion efficiency, and strong environmental variability, so the requirements for energy storage batteries are high. LiFePO4 plays two purposes in solar power generation systems, one is energy storage and regulation, and the other is balance Load, which converts the electrical energy output by the solar power system into normal electrical energy and stores it for use when the power supply is insufficient. Take ITEHIL's 100w solar panel and its matching 500W LiFePO4 power station (lifetime of 20 years), the energy storage battery required to have a long service life, stable performance, high energy efficiency, and adaptability to the environment Strong and other characteristics, so choose LiFePO4.
Why choose LiFePO4. because LiFePO4 has high energy, high energy storage efficiency, long cycle life, low cost of use, large input and output power, wide operating temperature range, no memory effect, maintenance-free, and 2000 charge-discharge service life, safety And the characteristics of green and environmental protection.
The voltage platform of LiFePO4 is 3.2V, the specific energy is more than twice that of lead-acid batteries, and the volume specific energy is 4 to 5 times that of lead-acid batteries. If LiFePO4 battery is used instead of lead-acid batteries for photovoltaic power generation systems, it can be greatly reduced. The space occupied by the battery reduces the maintenance workload.
LiFePO4 has a wide range of applications, and its safety is greatly improved compared to lead-acid batteries. At the same time, the rate characteristic of LiFePO4 is 5C～15C, and the conversion efficiency is greater than 95%, while the rate characteristic of lead-acid battery is 0.1C～1C, and the conversion efficiency is greater than 80%. Therefore, in terms of energy storage efficiency, LiFePO4 has a great advantage, which other energy storage batteries cannot give.
The rapid development of solar power generation systems puts forward higher requirements for energy storage systems. The LiFePO4 power station's characteristics of high energy storage efficiency, long life, and good charge and discharge performance determine that it is very suitable as a new energy storage power source, and its operation is stable and reliable. , Good prospects for use.
