hello,
since am really new to all this , i really need your help. i am student in the University and am working on a project , where a solar panel is used to charge some batteries , that are needed to power a computer board and some other appliances. my task is to test the current or the voltage coming from the batteries or charge controller, since the appliances are connected to the charge controller, to see if it is capable of powering the appliances. i need at least 12 V .. the whole thing will need max. 25-30 W .. so the current should be a max of 2.5 A. I have to use a microcontroller (to measure and test the voltage) and a relay, to switch the relay On when the batteries are capable , or to switch it off when the batteries dont supply enough power. my question is , which microcontroller and relay are suitable for such thing? they have to have low power consumption. i hope i made it clear.
thank you
