Have any other users experienced this. My battery controlled via a KH10 inverter seems to import and export more in self use mode. It seems to be triggered by a rapid change in load.
My solar is an older system that is AC coupled rather than through the KH10.
The attached graph has the grid connection as the green line. This is measured through an independent CT. The clouds are running across the panels so it is pretty spikey, but even so this seems new.
Do you have your FoxCloud2.0 App or the website v2 graph for the same timeframe?
Are you aware of any firmware updates that have been loaded, and even if not, then Fox can change backend database values and push these to the Inverter.
To my eyes, your graph looks "normal" as the import spike seems to be caused by temporary loss of solar, and your EV charger kept going, so the system had no choice but to draw on the mains to supply.

Yes okay it is visible in fox ess cloud (v2). I suppose the battery had trouble with the erratic solar (Gen load) swinging from discharge to charge, and basically said - send it to the grid while I get sorted out. I just hadn't seen it before.

It maybe one to keep an eye on for a bit and see how it reacts. Is your battery SoC missing from that graph, or are my eyes bad this morning?
I left it off for clarity. Here it is. I will keep an eye on it.

You had me worried there the battery had stopped working, well good luck on the system behaviour.
