  • 18 volt solar panel usage

    18 volt solar panel usage

    12v batteries are rated to be charged at 12v or a maximum of 14 volts depending on the type of battery and its state of charge. A fully drained battery will accept higher voltage but as the battery will get charged the input voltage limit will decrease so if you'll connect a 12v or 24v solar panel directly with the battery it may. if you're using a 5W solar panel then yes you can connect different voltage solar panels directly to the battery. But, for more than a 5w solar panel you have to use a charge controller which will.
