You can use a 24V solar panel to charge a 12V battery, but it is not a good practice you should consider. Ideally, your solar panel should be sized to match the voltage of your battery. Using a panel that is too large or too small compared to your battery will create complexities in planning your solar power systems.
The safest way to charge a battery using a solar panel is also to use a charge controller. In the case of a 24v solar panel and a 12v battery, the charge controller would limit the amount of energy from the panel to the battery, especially when the battery became nearly fully charged.
PWM solar charge controllers can also be used to charge a 12V battery with a 24V solar panel. They adjust the voltage and amps coming from your solar panel to match the battery similar to MPPT charge controllers. However, PWM solar charge controller is not as good at maximizing the power from your panel compared to an MPPT charge controller.
In the case of a 24v solar panel and a 12v battery, the charge controller would limit the amount of energy from the panel to the battery, especially when the battery became nearly fully charged. Without a charge controller, the battery would continue to receive energy even after the solar panel fully charged the battery.
To charge 12V batteries it needs Vbat (12V) + 5V to begin charging and the solar must be Vbat +1V to keep charging. Those solar panels Voc are probably more than 24V so you should be fine! Kirby, Good day to you. Thank you for your assurance. Something that is often overlooked is that 2nd number -the "30"
If you wire that module to a 12V battery, it is going to charge that battery at 8.3 ampere, and pull the voltage down to whatever the battery can handle. If the battery is pulled up to 14.7V for example, you will charge at 14.7*5.5 = 80.85watts. Woah, where did the rest of the power go?
