Around 250ah of power, ideally a 200ah battery, or 2x120ah batteries. A 500-watt panel setup (2x 250-watt panels) can easily charge a 200ah battery in a day, so you could have 2x200ah batteries charging if you are not running them flat every day.

How many watts should solar charging at 10A work

A 10A charge controller can handle 130 to 150 watts of solar power. 12V system often use 20A charge controllers, but if it is less than 150 watts, a 10A controller is enough. . Charge controllers are sized based on the solar system voltage and current or amps. The controller must be large enough to deal with the power. . Solar panel output does not always match its rating. Because of how solar power works,the output on average will be lower than its rating. A 150W solar panel in theory generates 750. . Charge controller amp ratings range from 1 to 60. The most widely used are 10A, 20A, 30A, 40A, 50A and 60A. Voltage ratings for charge. . MPPT charge controllers cost more than PWM because they are more efficient. But for a 10A charge controller, a PWM is sufficient.The following will illustrate the difference between an MPPT and PWM and why the latter is enough for small solar power systems.. If your solar panel is less than 150 watts, a 10 amp charge controller is sufficient. If it is higher than 150 watts, you will need a bigger controller, But if your solar panel output is exactly 150 watts, that will push the charge controller to the limit. [pdf]
