Night
The equipment shuts down all possible loads so that as little ener-
gy as possible is being consumed. The equipment remains in the
"Night" status until the following morning.
5.1.8 Parameters
Switch-on conditions: Frequency, voltage
The equipment will only switch from the "Waiting for feed condi-
tions" status to the "Operation" status if the feed conditions are
met. The mains voltage and the mains frequency must be within
certain limits, which are described by the switch-on conditions.
Voltage limit value/Delay time for night detection
If the DC voltage falls below the voltage limit value for longer than
the delay time, the equipment switches to the "Night" status.
Voltage limit value/Delay time for day detection
If the DC voltage rises above the voltage limit value for longer than
the delay time, the equipment switches to the "Waiting for feed
conditions" status.
Inverter stack switch-on time
The time for which the inverter stack is switched on during a start-
up attempt
Permissible voltage dip after switching on the INV stack
Prior to the start-up attempt, a limit value is calculated from the
present DC voltage and the permissible voltage dip.
If the start-up attempt causes the DC voltage to fall below this cal-
culated limit value, this start-up attempt will fail.
Delay until the next start-up attempt following failure on account of excess
voltage dip
After the failure of a start-up attempt, this delay must elapse before
the next start-up attempt is made.
Power limit value/Delay time for shutdown
If the power fed into the mains remains below the limit value for
longer than the delay time, the equipment switches to the "Waiting"
status.
Standard delay for a renewed start-up attempt following shutdown,
offset delay added to the standard delay after shutdown,
maximum number of times the offset delay can be added to the standard delay
Variable delay in the "Waiting" status,  Chapter 5.1.4.
Minimum DC voltage, fill factor (PV equipment parameter
)
If the DC voltage rises above a value resulting from the minimum
DC voltage divided by the fill factor, a start-up attempt is made.
