If a solar array has a voltage of 17V and the battery bank has 14V, the solar controller can only use 14V reducing the amount of power. With Pulse Width Modulation controllers, as the batteries approach their full charge, current to the batteries is regulated by "pulsing" the charge (switching the power on and off).
Learn more WhatsAppA 10A PWM charge controller can support a 120 W solar array to charge a 12 V battery bank (120W/12V = 10A) or it can support a 240 W solar array to charge a 24 V battery bank (240W/24V = 10A). For a 240W 12 V solar array to charge a 12V battery bank (240W/12V = 20A) a 20 amp PWM Charge controller is required.
