ABB solar inverter modbus rtu Night communication off

Kindly, we are trying to do a modbus rtu communication between a Delta plc and an ABB solar inverter.
It runs ok during the day, but each night the modbus rtu communication stops due to an unknown cause, and we have to restart the plc each following morning to have everything normal again .
We found in the manuals the following*** info.
How can we disable this night feature?
Could it be causing the communication stoppage?

* When there is not enough solar radiation to supply power for export to the grid (e.g. during the night), it disconnects automatically and goes into stand-by mode.
* Night mode (inverter automatically switches off) : The inverter is in night time switch-off mode (input voltage less than 70% of the set start-up voltage).
* Product manual TRIO-20.0/27.6-TL-OUTD (20.0 to 27.6 kW) https://library.e.abb.com/public/064...M000001EG).pdf

Thank you

 

Nope, I don't know of any way to stop it doing that - have you tried contacting ABB directly? - They are usually quite helpful.
