Charging Current = 300W / 24V = 12.5A. Therefore, with 300-watt solar panels and a desired charging rate of 10% of the battery capacity, we would need to be able to provide a charging current of 12.5A.

A 400-watt solar panel will charge a 100Ah 12V lithium battery in 2.7 peak sun hours (or, realistically, in about half a day, if we presume an average of 5 peak sun hours per day). A 10kW solar system will charge a 100Ah

In general, if your 300W solar panel and battery bank are both rated at 24V nominal, you would need a 15 Amp solar charge controller. If your solar panel is rated at 24V, but your battery bank is only rated at

So, if your 300W solar panel is rated at 24V (nominal), and you’re planning on charging a 12V battery bank with it, use an MPPT charge controller. If your solar panel and battery are rated at the same nominal voltage, you can use either a PWM or an MPPT.
When it comes to a 300 watt solar panel, the voltage should be an appropriate size for the system and controller in order to ensure maximum efficiency and optimal performance. The most common battery bank voltages are 12V, 24V, 48V, or even higher.
A 300 watt solar panel needs a charge controller to store power in the battery bank. If the controller is not properly matched with the panel it will not work, so knowing how to calculate the size is important. Fortunately the steps are really easy.
For a 300-watt solar panel, a 12v 150Ah lithium (LiFePO4) battery or a 300Ah lead-acid battery would be the best suit. To calculate the size of a battery bank I would suggest you consider the highest number of peak sun hours and multiply the number of peak sun hours by the rated wattage of your solar panel.
To fully charge a 100Ah 12V lithium battery using these 10 peak sun hours of sunlight, you would need a 108-watt solar panel. Practically, you would use a 100-watt solar panel, and in a little bit more than 2 days, you will have a full 100Ah 12V lithium battery.
12v 300 watt solar panel will produce about 16.2 amps and 18.5 volts under ideal conditions (STC). That is why you need a 30A charge controller with 300 watt solar panel, which will regulate the voltage output of the solar panel to safely charge a 12 or 24-volt battery.
