However, when sizing a charge controller for your 400W solar panel you’ll also have to pay attention to another rating: the Maximum Input Voltage rating of the charge controller (in Volts). Both of these ratings can be determined by using the specifications of your solar panel (s) and battery bank.
Selecting the Right Size Controller 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.
Typically, the size of the solar charge controller is calculated by taking the solar panels’ total wattage and dividing it by your battery bank’s voltage. This will give you the minimum amps your controller needs, and it’s often recommended to get a controller with a higher capacity to handle potential increases in power.
Charge controllers are rated according to amperage. Charge controllers are sized to cope with the input voltage and current from the solar panels and how this power is most efficiently transferred to the battery bank. A safety factor of 25% is added to the solar array amperage to compensate for environmental factors.
With a 200W panel on a 12V system, the amperage calculations would be: 200W / 12V = 16.7A 16.7A X 1.25 = 20.9A So select a charge controller rated for greater than 21A array current. An MPPT controller in the 30-40 amp range would suit this 200W solar panel well. What size charge controller for a 100w solar panel? For a 100W, 12V panel:

If your 400W solar panel is rated at 24V, and your battery bank is only rated at 12V, you should use an MPPT charge controller, and it should be rated at 40 Amps. If you use a PWM charge controller, more than 50% of your solar panel''s power production would go to waste.
Charge controllers are sized to cope with the input voltage and current from the solar panels and how this power is most efficiently transferred to the battery bank. A safety factor of 25% is added to the solar array amperage to compensate for environmental factors.
Charge controllers also have amperage ratings, so if you have a 200W solar panel that generates between 10A and 12A during peak generation times, your solar charge controller should be rated at 15A. It is always better to install a solar charge controller that can accommodate a little more than the maximum voltage and amperage the system can generate.
