FAQs about Solar Controller Selection
How to choose a solar charge controller?
More importantly, your solar charge controller must be able to handle the maximum voltage that the solar panels / solar array can produce. This is the controller's maximum input voltage. To calculate the maximum input voltage, you need to work out the maximum output of the solar array.
How to choose a solar panel controller?
The controller's maximum input voltage should be higher than the solar panel's open-circuit voltage by 10-15%. The controller's current rating must be 125% of the total current of the solar panels. This helps move power efficiently without overloading. For PWM controllers, focus on the battery voltage and the controller's current rating.
