Hi,
In order to export energy to grid I am trying to set negative AcPowerSetPoint for an ESS system using d-bus script. Positive values always works, like in the example below:
#dbus -y com.victronenergy.settings /Settings/CGwacs/AcPowerSetPoint SetValue 50
but
#dbus -y com.victronenergy.settings /Settings/CGwacs/AcPowerSetPoint SetValue -50
return: dbus: error: no such option: -50
Thanks,
Mihai
