I am completely new to elecrical engineering, but I want to give it a shot and am really interested in learning more details about how all of it works. I've had an advanced physics course in high school, but that's about it, so please bear with me while I'm trying to get into it.
Now onto my "test project", which will be my first electrical engineering project after building a electromechanical motor in high school.
I want to create a battery powered water pump, which can be charged by a solar panel (think about it as a portable garden hose). My idea is that the solar panel charges the battery, and the battery powers the pump.
Here are my questions:
- What special requirements do pump, battery and solar panel have? I found a 12V 20000mAh battery, and a 12V solar panel. Also, I found a water pump that needs 12V of power to work. Are there any more requirements for the components to work as I want them to?
- How do I switch the battery from charging to actually powering the hose? Can it do both?
- How do I detect (and/or display) the current charge of the battery?
Thanks for your help! If I am missing anything, please let me know.
