mppt vs pwm

PPT doesn't exist. I didn't see it in your link. They did say the power point tracker is a dc/dc converter. In other words it's pwm control. Virtually all dc/dc converters are pulse width modulated.

There's no such thing!

When the charger controller is not working in mppt mode, it's working as a voltage regulator (constant voltage). That means pwm control.

I think maybe it's this...

"the controller is not looking for maximum power, but only the power needed to supply the demand."

Just because one person doesn't know or understand something doesn't mean it doesn't exist. From Arizona wind and solar. click

Excerpt

How a Maximum Power Point Tracker Works:

The Power point tracker is a high frequency DC to DC converter. They take the DC input from the solar panels, change it to high frequency AC, and convert it back down to a different DC voltage and current to exactly match the panels to the batteries.
