Manual Energy Storage Inverter ESI-S
Commissioning instructions 147
−
If the start/stop menu reads ‘ACK. FAULT’ (i.e. ‘acknowledge fault’), the inverter
has encountered a fault that needs to be corrected before the inverter can be
started. Refer to
for troubleshooting the problem.
−
If the inverter when activating the start menu displays a message to indicate that
it is remote control mode, the inverter either has to be started by remote control
or the remote control mode has to be deactivated. More information about the
remote control functionality is given in
and
Section 7.9.2.4
.
8.8 Step 7: Generate power or filtering
Once the system is connected to the supply and is running, the system can start to
charge or discharge the battery. Initially a low value can be set which can then be
gradually increased to the nominal inverter rating. When power quality features are
required, and if a harmonic load is present, the filtering performance can be tested by
selecting a harmonic, e.g. of order 11, and verifying if it is filtered properly.
−
For setting up the inverter’s main harmonics selection go to
[/Welcome/Settings/Customer set./Main settings/Main harmonics]
−
For setting up the inverter’s auxiliary harmonics selection go to
[/Welcome/Settings/Customer set./Auxiliary settings/Aux. Harmonics]
For more information on the main and auxiliary settings concept and on the setting up
of harmonics, refer to
Section 7.9.2.1
Once the harmonic is selected, analyze the spectrum of the line currents to see if the
selected harmonic is filtered. Refer to
Section 7.8.2
for more information on displaying
measurement results. If the harmonic is not filtered properly (e.g. if it is amplified),
deselect the harmonic and refer to
for troubleshooting the problem.
When harmonic load is not present, the inverter can be tested by generating static
reactive power. Initially a low value can be set which can then be gradually increased to
the nominal inverter rating.
−
For setting up the inverter’s main reactive power feature go to
[/Welcome/Settings/Customer set./Main settings/Main PFC/Bal.]
−
For setting up the inverter’s auxiliary harmonics selection go to
[/Welcome/Settings/Customer set./Auxiliary settings/Aux. PFC/Bal.]
Set the ‘PFC Type’ item to ‘Static cap.’ and choose the desired value for the item ‘Q
static’.
For more information on the main and auxiliary settings concept, refer to
Section 7.9.2.1
Once the reactive power is selected, analyze the inverter current. Refer to
Section 7.8.2
for more information on displaying measurement results. Refer to
in case of
problems. Disable the reactive power setting after the test if it is not required by the
user.
