Huawei SmartLogger3000 User Manual

Parameter Description Remarks
String monitor The inverter monitors PV strings in real
time. If any PV string is abnormal (such as
the PV string is shaded or the electric
energy yield decreases), the inverter
generates an alarm to remind
maintenance personnel to maintain the PV
string in a timely manner.
If PV strings are often shaded,
you are advised to set String
monitor to Disable to prevent
false alarms.
String detection
reference
asymmetric
coecient
Species the threshold for determining PV
string exception. The false alarms caused
by xed shadow shading can be controlled
by changing this parameter.
This parameter is displayed
when String monitor is set to
Enable.
String detection
starting power
percentage (%)
Species the threshold for starting PV
string exception detection. The false
alarms caused by xed shadow shading
can be controlled by changing this
parameter.
OFF at 0% power
limit
If this parameter is set to Enable, the
inverter shuts down after receiving the 0%
power limit command. If this parameter is
set to Disable, the inverter does not shut
down after receiving the 0% power limit
command.
-
Maximum
apparent power
(kVA)
Species the output upper threshold for
the maximum apparent power to adapt to
the capacity requirements of standard and
customized inverters.
If the maximum active power
equals the value of Smax_limit,
this parameter is not displayed.
Maximum active
power (kW)
Species the output upper threshold for
the maximum active power to adapt to
dierent market requirements.
For 1000 V inverters, this
parameter is congurable only
for the SUN2000-25KTL-US, and
the maximum value is 27.5 kW.
Tracker controller Selects a controller vendor. -
Adjust total
energy yield
(kWh)
Species the initial energy yield of the
inverter. This parameter is used in inverter
replacement scenarios. Set the initial
energy yield of the new inverter to the
total energy yield of the old inverter to
ensure continuous statistics of cumulative
energy yield.
-
Duration for
determining
short-time grid
disconnection
(ms)
The standards of certain countries and
regions require that the inverter should
not disconnect from the power grid if the
power grid experiences a short-time
failure. After the fault is rectied, the
inverter output power needs to be quickly
restored.
