Well, a constant voltage algorithm would not be a MPPT becuase he max power point varies with intensity.
Remember, your trying to put a constant load on the solar array which can mean regulating the array voltage, with the restriction that the charging voltage/current remains correct.
To throw a monkey wrench into the fan, you could say put back power into the grid when our done charing the batteries.
That diagram is an oversimplification.
In any event suppose I had a home system that:
1. Had wind power
2. Had a back-up generator
3. Had a solar array
4. Could sell back to the grid.
5. Had an MPPT on the operating point.
6. Had an MPPT array position tracker as well.
7. Had a way to dust off the array to remove snow, etc.
8. Could run off of the battery storage.
Now, throw in some clouds, rain and snow. So maybe an astrological calendar is in the future of this system.
