The importance of batteries in solar panels

The battery (Lifepo4 battery) is an important device of solar power supply system, its main function is to store the electrical energy sent by the solar panel in the battery instantly for the use of electrical equipment, the battery has the role of storing electrical energy and stabilizing the voltage.

　　The main technical parameters of the battery are voltage and capacity. Voltage refers to the rated voltage of the battery, that is, the normal working voltage, generally 3V, 6V, 12V, 24V, 36V, etc. Capacity refers to the battery's ability to store electricity, generally common 4AH, 6AH, 12AH, 20AH, 40AH, 60AH, 120AH, etc.. Such as 40AH battery as an example, said to 4A current to the battery charging, 10 hours can be full; if charged with 1A current, it will take 40 hours to be full. Conversely, the same is true when discharging. In general, the battery charging and discharging time, according to 10 hours charging and discharging rate is appropriate.

Of course, if you need we can customize Lifepo4 battery for you or give you a label production, we will be more your needs to provide different specifications of lifepo4 battery, of course, you can also specify what material to use solar cells, is lithium battery, or lithium iron phosphate battery.

　　The point to note is that when charging the battery with solar cells, the voltage of the solar cells should exceed the working voltage of the battery by 20%-30% to ensure normal charging of the battery. Such as charging a 6V battery requires 8-9V solar cells, charging a 12V battery requires 15-18V solar cells.

　　As for charging the battery with solar panels, how to match is good, mainly depends on your actual needs, of course, you can also consult us how to make their solar power system l use more fully.
