The relationship between PV input voltage (V

) and input power (P

)

is shown in the following example. Once PV input voltage is less than

450 V, the relation of V

and power is:

The typical efﬁciency chart related to V

and P

is shown below.

NOTE

Results may vary due to test equipment tolerances and product

differences.
