MPPT Maximum Power Point Tracking is electronic tracking. The charge controller looks at the output of the panels and compares it to the battery voltage. It then figures out what is the best power that the panel can put out to charge the battery. It takes this and converts it to the best voltage to get maximum AMPS into the battery.
