0,00
Relates to two/three Sunny Island in parallel con-
figurations (see Chapter 11.6.1): If the cumulative
load on all Sunny Islands raises above this value,
the Slave3 Sunny Island will be activated
If one of the parameters 422, 423 or 424 is set to a
value different from 0.00, all these parameters
have to be set to reasonable values.
In a system where no Slave3 is present, the setting
of this parameter should be equal to the setting of
“423_Ps2on3off”

Relates to two/three Sunny Island in parallel con-
figurations (see Chapter 11.6.1): Delay before a

If the current that flows into the grid/generator ex-

DroopMainsForm and mains is active.
