5.9.4 Soft Start
Sunny Mini Central units with Reactive Power Control are equipped with a soft start function. After
reactivation, for example after a voltage fault or frequency fault, the soft start function increases the
output of active power gradually (gradient function). The capacity increases by 10 % of the nominal
power per minute.
This process is deactivated on delivery.
5.9.5 Phase Assignment
The "Phase" parameter allows the Sunny Mini Central units to be assigned to phase L1, L2 or L3. This
function allows a communication command to be sent only to the inverters with the specific phase
setting when using the Power Reducer Box.
