3.7.2 Measured PV voltage is over 0Vdc at night or even without PV modules' connection,
how is it possible?
This happens because PV input is directly connected to the DC-bus. When there is not enough voltage from
PV modules to generate the desired AC voltage, the voltage value shown on the display will be the DC-bus
voltage and it is the only PV voltage sensor.
Figure 14: DC-bus
DC-bus joins battery DC/DC converter and PV modules input with the rectified AC voltage (equal to Vgrid*√2)
so the voltage shown will be the highest among them.

3.7.3 Is it possible to set the SOC strategy parameters using the display?

Yes, it is only necessary to follow the instructions below:
Main menu > Configuration > Enter Password > 0 3 3 2 and press the OK button.
After this process a star will appear after configuration (CONFIGURATION) to confirm that the password
has been detected and now the configuration is free to be changed.
MAIN MENU > CONFIGURATION > OPERATION MODE > select the desired operating mode > SOC
parameters.
After following this route all SOC parameters will be available. SOC parameters are included in the
"Installation and Operation Manual".
It is possible to configure SOC strategy parameters using INGECON SUN Manager too.
Important note: wrong configured SOC parameters may cause problems, alarms or even damages to the
device or the battery bank. They shall only be modified by qualified personal.

3.7.4 Is there a procedure to check the status of digital inputs or outputs (I/O)?

The status (on/off) of inputs and outputs is available in the display in the MAIN MENU > MONITORING >
MONITORING I/O.
They can be checked using the INGECON SUN Manager as well, in the "Online Data" tab.
