2. Current measurement correction
Inside the “Calibration” sub-menu:
If there is a difference between the current being read by the HMI and the current
circulating through the system, the reading can be corrected with adjustments from this
menu.
Note: It is best to perform the calibration when the battery SoC is between 40% and 60%.
Performing the calibration within this range allows the user to change between charge
and discharge status, and to take several points at each of these, making it possible to
perform the calibration in just one operation, without ever reaching 0% or 100% SoC,
which would otherwise trip an MCP safety.
Once on this screen, clicking the reset button clears any stored calibration point, leaving
a blank sheet to begin the calibration.
Calibration begins by charging or discharging the battery to the maximum current value
indicated on the data sheet provided by CEGASA, or the maximum current the inverter
can supply on the installation, whichever is less.
Once the current is read and displayed in the “Measured” box, the actual current can be
written in the “New current point box” and then “Add” can be clicked.
The current value in the inverter can then be changed to a new point and the previous
step repeated.
Calibration is performed by starting at the maximum charge current, passing through
several intermediate points, 0 current value, several intermediate discharge points and
maximum discharge current.
When
calibration has finished, press “Finish” to store the new calibration points.
Note: Calibration is done using the point-slope method, interpolating the calibration
points between 2 manually inserted points. Consequently, it is not necessary to calibrate
the current transformer at all working points because the software calculates the
intermediate points.
