Charge controllers are measured in amps. The basic rule is the controller amp rating must be higher than the amps of the solar panels or solar array. The formula is: Solar panel watts / volts = amps + 20% = charge controller size So with a 12V 300 watt solar panel, the formula looks like this: 300 watts / 12V = 25 amps +.

A PWM charge controller is ideal for a 12V or 24V 300 watt solar panel, provided the battery voltage is similar. If the solar panel voltage is much higher than the battery, use an MPPT charge controller. For example, a solar panel is running at 18V VMP and has a 5.2 LMP. A 12V battery is connected to the system and is charging at 13V (the
300-watt Solar Panel How Many Amps and volts? 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.
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 12V, you
What size charge controller for a 100w solar panel? For a 100W, 12V panel: 100W / 12V = 8.3A. 8.3A x 1.25 = 10.4A. Choose a controller rated for greater than 10.4A. A small PWM or 15A MPPT controller would safely handle this 100W solar panel. How many watts can a 100-amp charge controller handle?
To size a solar charge controller, take the total watts of your solar array and divide it by the voltage of your battery bank, then multiply by a safety factor of 1.25. This calculation will give you the output current of the charge controller. For example, a 1000W solar array divided by a 24V battery bank equals 41.6A.
Select a solar panel system rated at or above this wattage to ensure you can charge your 200Ah battery efficiently while accounting for inefficiencies during the charging process.

If the controller is not properly matched with the panel it will not work, so knowing how to calculate the size is important.
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.
If the 300W solar panel (or array) is rated at 12 Volts, you would generally require an 8 AWG copper wire. However, if the solar panel is more than 25 feet away from the charge controller, you will be required to use thicker wires to limit the voltage drop between the solar panel and the charge controller.

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.
If you have a 300 watt solar panel, it can generate approximately 1.22 kWh per day or 438 kWh per year. These figures depend on the irradiance of your area, the efficiency of your power inverter, and your panel’s voltage and current. The maximum power a solar panel can produce depends on the panel’s voltage and current, which are optimally matched.
If your 300W solar panel (or solar array) and battery bank are both rated at 12V nominal, you would need a 30A solar charge controller. Here’s a table that shows you what size charge controller you’ll need for your 300W based on its nominal voltage, the nominal voltage of the battery, and the type of charge controller:
