How does inverter communicate its maximum allowed power to Cerbo GX

I have written a driver that allows a Xantrex Freedom XC 2000 Marine to communicate with the Cerbo GX using NMEA 2000 protocol over CAN. It is working well with one exception. If I draw more than about 2A out of the inverter, the inverter tile shows a red bar. This apparently indicates that the inverter is overloaded - which at 2A it is not. It is a 2000W inverter.

In my case, I’m pretty sure it is because the Cerbo does not know that maximum allowable current out of my inverter. So the alarm is triggering at a very low value. Everything I’ve read says to set this in ESS mode, but this is a marine application with no ‘grid’.

I assume there is a dbus path that can be set to tell the Cerbo what the inverter maximum allowable values (either power or current) are. Does anyone know how this is done?

Thanks

Does anyone have a Victron inverter of any type connected to a Cerbo and have access to dbus-spy. It would be interesting to see a screen shot of all the dbus paths populated by the inverter.

It turns out that the gauges displayed in the Overview page have limits that are set under the Settings-General-Display menu. These have to be set to match your inverter nominal power output.

I’m still new to the Cerbo world :slight_smile:
