power measurement; if the PV power increases, further voltage
adjustments in that same direction are performed until the PV power no
longer increases.

INSTRUCTION:
PV input power from the array may be unbalanced between the three
MPPT zones, however every effort should be made to design within
one string count difference. See Table 3-3.
When designing the PV system ensure each PV string within a single
PV input zone includes the same module type (Mfg and ratings),
same series module count, and same module orientation (tilt and
azimuth) to maximize MPPT performance and energy harvest.
