User Manual

Shut-down requ.
PpvStop *

If Ppv < PpvStop for the duration of Tstop, the Sunny Central goes into
"Shutdown" mode.

Tstop
Grid Monitor.
PacMax *

PacMax is the maximum power output to the grid. If this limit is exceeded, the
Sunny Central reduces the power.

PpvMin
Check *

PpvMinCheck appears only after entry of the installer password. If
PpvMinCheck is set to "off", the Sunny Central continues to operate after the
shutdown conditions have been met. As a result, the Sunny Central operates
even at night and needs to draw its operating power from the grid.

Other
E-Total Offset

With this parameter, the internal energy counter can have a constant offset
applied to it. It may be a good idea to adjust this parameter after replacement
of the Sunny Central Control.

TMax. cabinet*

If the TMax. cabinet temperature is exceeded, the warning "cabinet Temp." is
generated.

TMin. cabinet*

If the cabinet temperature drops below "TMin. cabinet", the warning "cabinet
Temp." is generated.

output required for the two Sunny Centrals to be disconnected from each other.
The default setting is 80 %.

P-Prv. Team

In Team systems, this parameter defines the percentage of the nominal power
output required for the Team contactor to close. If "Pac smoothed" falls short of
this value, the Team contactor closes, causing both solar generators to feed one
inverter. The default setting is 20 %.
