What Size Solar Panel Do You Need to Charge a 100Ah Battery?

The controller should be able to handle the voltage and amperage of your solar panel and battery. For example, if you have a 12V battery and a 100W solar panel, you will need a charge controller that can handle at least 8.3A of charging current (100W/12V = 8.3A). If you have a 24V battery, you will need a charge controller that can handle at

How Many Solar Panels Can a Charge Controller Handle?

The battery size determines what solar array size can be used with the controller. The higher the battery voltage, the more solar panels you can use. Charge controller amps x battery voltage = solar panel size in watts. 30A x 12V = 360. 30A x 24V = 720. Again this should only be done if the controller VOC is not exceeded.
