All our AEMs (PMICs) share the same purpose: manage the power from an harvester to a storage and/or a load.
However, their coldstart, MPPT ratio and timing might be different to be adapted to the source they should harvest from. For more details, please see “What is the MPPT ratio?” question.
To choose wisely your PMIC, please keep in mind it must be adapted to your harvester and its behavior.
