I am newbie in electrical engineering. Recently, I ordered a solar DIY kit package which includes a solar panel(10W, 12V, 1A), a solar charge controller and an inverter(DC 12V to AC 240V). I plan to use it to charge a 12V battery.
Here I have a question about this DIY package, To my understanding, to charge a 12V battery, the output DC voltage of solar charge controller should be higher than 12V. But the solar charge controler's rated current is: 10A / 20A / 30A / 40A / 50A /60A. According to the wattage(10W) the solar panel can generate, the solar charge controller's output DC voltage will be less than 1V. So, how this solar DIY package can charge the battery?
