Dashboard showing incorrect solar generation

I have installed a 5kVA Multiplus with a 5kW Fronius Primo, monitored by a Cerbo. The Multiplus is programmed with the ESS assistant, and feeds excess power back to the grid.

Although the data is captured for the consumption and PV generation in the advanced tab, it does not reflect on the dashboard. Below data from April 20 on dashboard and advanced tab. Around 20kWh generated, but only reflecting 8.4kWh. The consumption data is also incorrect.

The ESS is set on "with battery safe" and battery at 100%. I'm experimenting with lowering the value to 85%, and this seems to allow the correct new information to be captured on the dashboard, but not historic. There are 4 x US2000c batteries.

Has anyone experienced this before? If the Fronius lost comm's it could make sense, but there is no missing data.

Hi @j-n-wise,

Have you selected AC-out in Settings - PV Inverters - Inverters for the PV inverter?
