Enable Quattro inverter when generator is active

I have an off-grid installation that has a Quattro 24/5000/12-2x30 inverter and is controlled by a Color Control GX.
When nobody is present in the house we want to disable the Quattro inverter as it has a high power consumption. There is a small Phoenix Inverter that takes over in this case.
The Color Control GX activates a gas generator when the battery level drops to low. This generator is connected to the Quattro. I hoped that the CCGX would enable the Quattro as well when it enables the generator but this is not the case.
Is there a way to automatically enable the Quattro when the generator is enabled?
