How many watts can a solar panel run?

12V 20A controllers have a maximum capacity of 240 watts. The only way to run a 300W solar panel is to use a 24V 20A controller or higher. it is true that solar panels do not always run at their stated output. A 300W panel might only reach 200 watts during cloudy days for instance.

How many watts can a 20A charge controller run?

20A Charge controllers are designed to run 12V or 24V solar systems. This voltage limit determines how many watts the controller can run. The formula is charge controller voltage x amps = maximum watt capacity. 12V x 20A = 240W 24V x 20A = 480W Larger charge controllers have support for 48V systems as well.

Is a 20A controller enough for a 500 watt solar array?

If you want to run a 500 watt solar array, a 20A controller is not enough. As we pointed out the limit for 12V 20A controllers should be 200 watts, or 240 if you want to go the limit. but anything beyond that and you need a bigger controller.
