75128S Lithium ion battery 12V 24V with solar controller for solar street lamp
In the old times, the lead-acid battery was applied to light on the street light. And the solar panel is used as the power supply, transfers the sun power to electric power and stored in the battery. So there is no need to build electric lines, and this is more convenient. But the lead-acid battery is big in size and heavy in weight, so people always need to put the battery underneath. Now there is a much more convenient way to solve the problem, which is to replace the lead-acid battery with lithium ion battery. The lithium ion battery is much lighter to be installed under the solar panel. And we connect the solar controller with lithium battery together into the aluminum alloy case, this system furtherly easier the installation procedure.
Our 75128S is designed to build in a lithium ion battery 12V 20Ah to 60Ah or lithium ion battery 24V 10Ah to 30Ah. The solar controller inside can be PWM or MPPT, power from 30W to 80W, to meet the requirement of wide range customers.
With our rich experience, we can customize a solution for customers. You can tell us the power of the solar panel also the LED light, and your requirement, then we can provide a solution for you within 24hrs. The solution can meet your requirement, and also control the cost within a reasonable and low range.
