♦Solar street light battery Project Overveiw

12M 90W solar street light(with LiFePO4 battery) project is designed for instead 230V 250w normal street light which is powered by grid electric. This full system is formed by 1pc 24v 90w LED light, 4pcs 12v 100w solar panels, 24v 50AH LiFePO4 battery pack(include BMS), 24v solar controller/charger, 12m height pole and accessories. It is charged by solar panels within 12hours (8hours full power, 4hours half power), could power the 90W LED light works more than 12hours after full charged. Light poles installation distance can be 30meters, all of the products are waterproof, battery will be buried underground.

24V Solar street light battery solution

GeePower® 24V 50AH Solar street light battery is assembled by 8pcs 3.2V 50AH GPLFP10192320 LiFePO4 battery cells in series.

GeePower®3.2V 50AH LiFePO4 polymer cheap lithium batteries  can be used to Electric vehicles and other energy storage areas. These Lithium Iron Phosphate (LiFePO4) batteries, produced by GeePower here in  China, are rated at more than 2000 recharge cycles, can be assembled in series and parallels with a battery management system (BMS).

The Lithium Iron Phosphate Battery is a type of rechargeable battery based on the original lithium ion chemistry, created by the use of Iron (Fe) as a cathode material.
Already passed all of the safety tests(overcharge, overdischarge, over temperature, short circuit, drop, Crush, Needle puncture tests, etc). These battery cells do not catch fire, no explosion and no leakage.

♦Solar street light battery Advantages

  • 30years experience in rechargeable batteries
  • 10 years experience  in Lithium batteries
  • geepower® battery can be above 2000 recharge Cycles
  • poor electrolyte, can be operated in any directions
  • can be discharged at high current(up to 5C), charge current(up to 3C)
