10.5.1 Shadowing
Description
The "Shadowing" option is an extended MPP tracker. When
the option is switched on the MPP tracker performs an addi-
tional search at regular intervals.
The MPP tracker then searches for the maximum power
over a wider voltage range.
This option should be switched on if shadows regularly pass
slowly over the PV modules in the course of a day. These
types of moving shadows can be caused by (e.g.) chimneys
or trees. This option has a relatively small effect in the case
of fast-moving shadows, e.g. from passing clouds.
The option is set depending on the size of the shadowing.
