Huawei SUN2000-90KTL Series User Manual

Parameter Description
PID compensation direction
(or Crystalline silicon PV
compensation mode)
When the external PID module compensates the PID voltage for
the PV system, set Built-in PID compensation direction to the
actual compensation direction of the PID module so that the
inverter can output reactive power at night.
This parameter is displayed when PV module type is set to
Crystalline silicon. Select PV–positive oset for P-type PV
modules. Select PV+ negative oset for N-type PV modules.
String connection mode Set the connection mode of PV strings.
● When PV strings connect to the SUN2000 separately (fully
separate connection), there is no need to set this parameter.
The SUN2000 can automatically detect the connection mode
of the PV strings.
● When PV strings connect to one another in parallel outside the
SUN2000 and then connect to SUN2000 independently (fully
parallel connection), set this parameter to All PV strings
connected.
Automatic OFF due to
communication interrupted
The standards of certain countries and regions require that the
inverter must shut down after the communication is interrupted
for a certain time.
If Automatic OFF due to communication interrupted is set to
Enable and the inverter communication is interrupted for a
specied time (set by Communication interruption duration),
the inverter will automatically shut down.
NOTICE
Setting this parameter to Enable may cause power grid connection failure
of the solar inverters, which
aects the energy yield.
Automatic ON due to
communication resumed
If this parameter is set to Enable, the inverter automatically
starts after communication recovers. If this parameter is set to
Disable, the inverter needs to be started manually after
communication recovers.
This parameter is displayed when Automatic OFF due to
communication interrupted is set to Enable.
Communication interruption
duration (min)
Species the duration for determining communication
interruption. Used for automatic shutdown for protection in case
of communication interruption.
Soft start/boot time (s) Species the duration for the power to gradually increase when
the inverter starts.
Shutdown gradient (%/s) Species the power change speed when the inverter shuts down.
Night-time hibernation The inverter monitors PV strings at night. If this parameter is set
to Enable, the monitoring function of the inverter will hibernate
at night to reduce power consumption.
