mppt vs pwm
Hi, A nice little video comparing mppt vs pwm with the batteries in bulk mode. mppt vs pwm
Forum Discussion
"Do mppt controllers operate in mppt throughout the entire charge cycle, or just during bulk/cc?"
Need to know what you believe MPPT mode is....
If it's the tracking algorithm that attempts to obtain the Vmp from the array - then the answer is that it DEPENDS. Some of the Blue Sky MPPT Controllers have only a Potentiometer that the user is required to set and forget (IMHO at best a joke the Vmp varies a lot and the pot is inside the controller). Another answer is mostly yes the tracking algorithm is active most of the time for higher end controllers.
Many controller show "MPPT" as one of the operational modes - it's simply there to help the user understand that the available lighting conditions are making it difficult for the controller to obtain and hold a Vmp setting.
As for the buck conversion stage again it depends
If the panel voltage is higher than the desired battery voltage them it is always functional - some proper controllers bypass the buck conversion stage if the battery voltage gets close the array voltage
