A solar charge controller plays an important role in prolonging the life of your solar battery. They protect batteries from the dangers of being overcharged and completely drained, both of which significantly reduce battery lifespan. The PWM charge controller is a good low cost solution for small systems, when solar cell temperature is moderate to high (between 45°C and 75°C).
Description
12V-24V Auto LCD Display 20A Solar Charge controller. This solar lighting system charge controller is designed for off-grid solar photo-voltaic systems, such as home solar system, solar traffic system, solar CCTV system, Wild automatic detection equipment, etc. The Pulse Width Modulation battery charging can greatly increase the lifetime of battery.
