Hi Guys,
Trying to manually control a Quattro with Cerbo GX via ModBus.
I have followed the ESS mode 2 & 3 documentation.
When ESS mode 3 (external control) is active, the SetPoint wont accept a negative number.
See screen shot to see Charger and Feed-In address status.
Has anyone come across this before?
I have tried -1, -10, -100, -1000 I just get the error as attached. Positive numbers are accepted without issue.
Thanks in advance!
