Hi everybody,
for my project, I'm using this solar shield in order to use some solar panels and a battery to power my Arduino: Solar Charger Shield V2.2 - Seeed Wiki
In order to protect the solar shield (where the maximum solar input is 6v) I would like to add some protection circuit between the solar panel and the input shield in order to avoid burning the shield.
This is because, reading the SP page info (https://www.seeedstudio.com/1W-Solar-Panel-80X100.html), during particular summer days the voltage could be more than 5.5v (also 10v).
Do you know some protection circuits in order to provide 5v as maximum voltage?
You can use a step-up/step/down (switch mode) DC-DC converter. Sometimes called a buck-boost regulator.
A step-down regulator will have a "drop-out" voltage . For example a drop-out voltage of 1V means if the input to the regulator drops below 7V, the regulator won't be able to maintain 6V out.
I'm not expert... I thought that this was a frequent problem.. is not there any solution ready to purchase?
