What size MPPT do I need?
You take the total watts of the solar array divided by the voltage of the battery bank. That will give you the output current of the charge controller. For example, a 1000W solar array ÷ 24V battery bank = 41.6A. The rating of the charge controller should be at least 40A.
Is a MPPT charge controller worth it?
Are MPPT controllers worth it? In general MPPT solar charge controllers are well worth the extra expense over PWM type. You can expect to gain 30% more power from your solar panel array, a great advantage in intermittently cloudy weather.
How many watts can a 15 amp MPPT charge controller handle?

How do I test my MPPT charge controller?
To test the regulator: Disconnect the positive cable between the battery and the panel. Measure the operating current by connecting the +ve from the multimeter to the positive cable from the panel, and the -ve from the meter to the positive battery terminal.
How do I know if my charge controller is bad?
The easiest way to test if the solar controller is working is to use a multimeter to test the output voltage. and look to the controller’s LCD display and Led indicator, if the output voltage is absent or very low, It means that the controller is not working properly.
