DBus PV Inverter showing as load on AC out

I have set up my Growatt inverter to publish data to Cerbo’s Dbus, position 1 (AC OUT). ESS Assistant is setup with PV inverter on AC OUT enabled.


The power generated is showing up in the dashboard, however it also showing up as a load on L1:

I also have another inverter in position 0 (AC IN) however that is being totalled on the AC out side for some reason.

You can see in Dbus I push all the data to L1 even though the actual power is across several phases (including L1), this is an aggregate of multiple single phase inverters. However if I change this manually in DBus for testing the same thing happens, the power just get added to AC loads.

Setup: 3x Multiplus II 48/10000 with Cerbo GX.
