How to choose the right solar energy battery

Nowadays, there are many kinds of solar energy battery on the market, the prices are different, and the quality of the products is uneven. How do we choose the solar energy battery that suit us?

First, you need to understand the voltage range of the equipment used in the lithium battery pack;

Second, you need to know the normal operating current of the device and the instantaneous starting current, or know the rated power of the device. Again, we want how long this battery pack will power the device. For the size requirements of the battery. If there are special requirements, it needs to be specially formulated by the manufacturer.

A few suggestions may help you purchase solar energy battery :

First, pay attention to the discharge benefits of lithium batteries:

The discharge benefit of a lithium-ion battery is judged based on the internal resistance of the battery itself and the current magnitude and temperature of the battery during use. Lithium-ion batteries are usually different from the old-fashioned "memory batteries". Lithium-ion batteries are used in the market to replace old-fashioned batteries, because lithium-ion batteries have no memory benefits, and because lithium-ion batteries are environmentally friendly, lightweight and easy to carry, but also because of lithium ions. The discharge efficiency of the battery is greater. However, the discharge benefit of lithium-ion batteries is also related to the use of lithium-ion batteries. The selection of high-quality raw materials can reduce the internal resistance of batteries, increase the discharge efficiency of lithium batteries, and the charge and discharge benefits of lithium batteries with different positive and negative materials. There are also differences.

Second, look at the battery board and look at the front. Looking closely at the surface of the tempered glass, in order to increase the production speed, the manufacturers often do not care about the silica gel that accidentally drops on the surface of the tempered glass. If it is not removed, it will affect the power generation efficiency of the panel.

Third, look at the battery. Many irregular manufacturers use broken battery pieces to form a seemingly complete battery piece for welding. This method is very risky, and may not be obvious at the beginning, but the spliced ​​battery piece is easy to be disconnected again later, affecting the whole piece. The use of panels.

Fourth, look at the back. Look at the effect of the back pressure, there is no unevenness after the pressure, such as bubbles, wrinkles and the like.

Fifth, look at the border. Many manufacturers use the manual frame method, manual frame can not guarantee that each time the force is just right, the frame is not tightly contacted, the shape is not strictly rectangular solar energy, the quality of the ordinary user identification solar panel is also strong. discount.

Summary: Now more and more families use solar energy battery as home backup batteries, so when you choose lithium batteries, you need to carefully compare them to prevent the purchase of inferior products.
