How To Make Solar Panels With Earth4Energy DIY Guide!
Discover what you can get with this DIY Solar Panels Guide
การนำ Charge controller Solar Cell มาใช้กับปั้มชัก 1นิ้ว มอเตอร์ dc 12v 300 w เพือ่ให้ทำงานอัตโนมัติในเวลากลางคืน โดยต้องใช้สายไฟเส้นใหญ่ในการต่อเข้า Charge controller และตั้งโหลด ออฟ ให้ต่ำไว้ก่อน เพราะมอเตอร์จะกระชากไฟในการเปิดการทำงานครั้งแรก และจะหยุดการทำงานตาม v ที่ได้ตั้งค่าไว้ การใช้งานมาหลายเดือนอุปกรณ์สามารถใช้งานได้ดี แบตขนาด 75 a 2ลูก สามารถใช้งานได้นาน 6-7 ชม.
Charge controller Solar Cell for use with a 1-inch induction pump motor dc 12v 300 w for automatic operation at night. By using a large wires to connect to the Charge controller and set the load to low. Because the motor will snatch the light on the first turn. And will stop working as set up. The device can work for many months, the battery size 75 a 2 balls can be used for 6-7 hours.
