Hello @Darren, I havent seen this for a while, so not sure what’s causing it. Did you get any power cuts around those points? can you look at the power feed at the exact moment it steps down?
What does the input processing look like for these feeds?
You can recompile cumulative kWh feeds from power data using the postprocess module available on the standard image.
Setup > Post Process
Click on create new: powertokwh
Select your power feed e.g solar
Enter a name for the new kwh feed: solar_kwh2
Swap the input processing around to use the new feed and feel free to delete the old one and rename the new one to solar_kwh again…
