Currently, if I use a scheduler to force charge my battery to 50%, it just keeps charging past the set SOC. I'm pretty sure this didn't happen before the most recent update.
My schedule and usage are shown below. You can see that I've set the Max SOC and the Forced charge cutoff SOC to 50%, but even though the battery is at 57%, it's being charged by my solar panels, and the house is being charged by the grid, which is not what I want. I'd expect that once the battery met the 50% cutoff, then the house would be charged by a combination of solar panels and grid, until the end of the schedule, and then revert to battery use.

You say this behaviour changed since a recent update... what do you mean, the Fox Cloud 2.0 App or the Firmware of your system was upgraded?

It looks on the surface that your schedule is working in the sense that once it gets to a 50% SoC it then is reverting to Self-use mode. The Self-use mode is deciding to let your battery charge to 100% and not function correctly either.

Self-use should be PV -> Load -> Battery -> Grid (export)
I don't use Self-use mode these days, but suspect it might just ignore the 50% max SoC you are wanting it to stop at.
Feed-in mode on the other hand, does for me at least seem to obey what I want mine to do, have battery supply the load, and send all excess PV out to the grid once the house Load has been supplied first.


Now you might be needing a reboot of your system as something has crashed in the Inverter, because to me it is not behaving correctly. You might just need a FW upgrade on your full system, and then everything might work as intended.

For ultimate control of your system, if FW upgrade does not work, or changing the mode to Feed-in for example, then you may need to look very closely at Home Assistant so that you can program logic into your system.


p.s. The house is never charged, it is only supplied.

A quite recent thread about same issue, I don't think they resolved the behavior either by looks of what I read
