How big is the lithium battery for 30w ip65 solar street light?

30W solar street lights are usually equipped with a lithium battery capacity of 12V/40AH. The following will explain in detail why this capacity of lithium battery is chosen.

First of all, the solar street light has a power of 30W, which means that the electricity consumed per hour is 30 watts. In order to ensure that solar street lights can work normally at night, a certain capacity of batteries is needed to store the solar energy collected during the day.

Secondly, lithium battery is one of the commonly used battery types of solar street lights, with high energy density and long life. When choosing lithium battery capacity, it is necessary to consider the working time and brightness requirements of solar street lights.

In general, the working time of solar street lights is 10-12 hours, which means that the battery needs to be able to provide at least 10-12 hours of electricity. The brightness requirements depend on the specific use environment and needs.

According to experience, 30W solar street lights equipped with 12V/40AH lithium batteries is a more suitable choice. This capacity of the battery can meet the working time and brightness requirements of solar street lights, but also has a high energy storage capacity.

In addition, the choice of 12V voltage lithium battery because the circuit design of solar street lights usually uses 12V DC power supply. This can simplify the circuit design and installation process, improve the stability and reliability of the system.

In short, 30W solar street lights are usually equipped with 12V/40AH lithium batteries. This capacity of the battery can meet the working time and brightness requirements of solar street lights, but also meet the requirements of circuit design and installation.
