Manual Energy Storage Inverter ESI-S
For detecting the CT-settings automatically, go to
[/Welcome/Settings/Commissioning/Auto CT detection]
When engaging the automatic CT detection procedure the inverter will execute the
following steps:
−
Deselect harmonics and reactive power/balancing settings previously entered by
the customer
−
Display a warning message to wait for the identification procedure to end
−
Check the voltage level of the DC capacitors, close the main contactor and start
the IGBTs
−
Close the DC contactor
−
Inject a small current into the supply
−
Record the current measured by the CTs and calculate the inverter CT ratios and
positions
−
Display a message indicating whether the CT identification ended successfully or
not
NOTE: The automatic CT detection is repeated automatically for all the units present
in a multi-unit inverter system.
