There is a virtual device on solar running in the flows. This happend in the past aswell (long before the virtual device excisted). Below the graph from the solar injected by the virtual device so you can see there was no gost value injected.
Happens when you count kWh or add at night.
So its not about when you are injecting but when and how it is being included in the metrics from the node red side.
Solar part one is via a meter ; part two is via virtual device. Virtual device runs on the cerbo reading the data from a shelly relais (which is switched off during the night). The real Node Red running on a PI reads the solar data via Mqtt to feed the EMS. In the historic off the EMS I don’t see any solar during the night. This means that the data doesn’t come from the meters.
If you substract Consumption - Solar you get the real consumption at that moment. Fault is generated in VRM.
This is not a realtime issue but rather a data dump or total calculation related something.
I have seen it happen when consumption/production totals are calculated or reported data sent. Its like it just dumps the figures there.
Is it a repeat time/pattern?
