Huawei SUN2000-175KTL-H0 - Upgrading the Inverter

No. Parameter Description Remarks
23 Apparent power
baseline (kVA)
Adjust the apparent output
baseline of the inverter.
-
24 Active power
baseline (kW)
Adjusts the active output baseline
of the inverter.
-
25 Power percentage
for triggering Q-U
scheduling
Species the reference apparent
power, in percentage. When the
actual apparent power of the
inverter is greater than the value
of this parameter, the Q-U
characteristic curve scheduling
function is enabled.
-
26 Q-U characteristic
curve
The inverter adjusts Q/S (the ratio
of the output reactive power to
apparent power) in real time
based on U/Un(%) (the ratio of
the actual power grid voltage to
the rated power grid voltage).
-
27 Q-P characteristic
curve
The inverter adjusts Q/Pn (the
ratio of the output reactive power
to the rated active power) in real
time based on P/Pn(%) (the ratio
of the actual active power to the
rated active power).
-
28 Cosφ-P/Pn
characteristic curve
The inverter adjusts the output
power factor cosφ in real time
based on P/Pn(%).
-
7.2 Upgrading the Inverter
USB ash drives of SanDisk, Netac, and Kingston are recommended. Other brands
may be incompatible.
NO TE
Delete the script le immediately after use to reduce information disclosure risks.
Procedure
Step 1 Download the required software upgrade package from the technical support
website.
Step 2 Decompress the upgrade package and copy all les to the root directory of the
USB ash drive.
