To switch the power source between solar panel and DC power supply
To switch the power source between solar panel and battery array
Application Examples:
If you are currently using a Tuhorse 500W solar pump on solar panel, and you wish to use a AC to DC 48V power supply to run the pump at night. Connect both power sources to this Auto Switch as shown in the photo. In a sunny day, the solar panel supplying the power to the pump's control box and the pump. When sun energy goes low, the power source will be switched over to the DC power supply automatically.
Just as shown in photos, wire is not included.
Note:
For the solar system that uses single solar panel that is less voltage than the power supply, the power supply should be manually shut off in order to use solar energy and turn back on when needed.
