mppt vs pwm

Hi Salvo,

So if the input to the controller is 33 volts does charging start earlier than if it is 16.5?

Does MPPT keep the voltage higher than the 12 to 13 volts surface for longer if the set point is 14.8?

For the majority of solar users here, the battery has the lowest SOC in the morning. At time there isn't enough irradiance to pump 30A into the battery. The battery will charge at perhaps 10A where charge controller efficiency is low. Surface charge will quickly increase battery voltage from say 12V to the 13V region, resulting in lower charge current.
