How to Choose Lithium-ion Solar Batteries?

Understand Lithium-ion Solar Battery

Lithium-ion solar batteries have great advantages over traditional batteries, such as larger storage capacity; high energy density, reducing the weight and size of the battery, as lithium-ion solar batteries are smaller and lighter; and longer lifespan. They support deep discharge and can use their maximum capacity; have longer shelf life; very low self-discharge, only 3% per month. They require no maintenance; and have no memory effect. Lithium-ion solar batteries do not emit pollutants; they are safer and more reliable.

What should you know when choosing a Lithium-ion Solar Battery for home use?

Lithium-ion solar batteries are not simple building blocks, they are complex electrochemical components, however, technical details and relationships can sometimes be difficult to understand - especially if you are not particularly proficient in technology, let alone physics and chemistry. To help you find your way in the jungle of technical terms, we have listed some basic features of lithium-ion solar batteries that you need to consider.

Power factor: 

The C-rate reflects the discharge capacity and maximum charging capacity of the backup battery for home use. In other words, it indicates how fast the residential battery can discharge and recharge relative to its capacity. A coefficient of 1C means that the lithium-ion solar battery can be fully charged or discharged in under an hour. A lower C rate represents a longer duration. If the C factor is greater than 1, the lithium-ion solar battery will need less than an hour. With this information, you can compare residential battery solar systems and reliably plan peak loads.

Battery capacity: 

Measured in kilowatt-hours, it simply represents the amount of electricity that the device can store. You can find lithium-ion solar battery packs for home energy storage on our product pages. Please note that most batteries are expandable; that is, as energy demand increases, storage capacity can be expanded.

Battery power: 

This refers to the amount of electricity it can provide at any given time, measured in kilowatts. It is important to distinguish between capacity and power. The former refers to the energy you can accumulate, so you can use it when your solar panels do not produce electricity. The latter represents the number of appliances that can be connected simultaneously, depending on their power. Thus, if you have a high-power but low-capacity battery, it will discharge faster.
