Can you check that the inverter thinks you have a CT clamp installed (assuming you are using a CT clamp to measure flow and not a meter) - it sometimes becomes unset after a firmware update.

You can check if you go into Settings, Feature, Meter/CT - it should be set to CT, if it is not change it ...

The problem is definitely related to the minimum on-grid soc setting. If the soc is below that, it feeds-in on negative load, then when I set the minimum on-grid soc to a value lower than the current soc, the inverter switches from feed-in to battery charging.

I thought too soon that battery charging works as expected.

It seems that if the battery SoC is at or above minimum on-grid SoC, the battery is charged if there is negative load.

If the battery SoC is below the minimum on-grid SoC, I get feed-in instead of battery charging.

After both setting a bunch of parameters to the same value that was shown in the web UI, and contacting Foxess support, battery charge on negative load seems to work again.

I'm unsure whether that is now caused by (re)setting the parameters or by something the support did. The parameters all do ...

After a firmware update of my H1-6.0-E inverter and the ECS-2900-2 battery stack, the battery is no longer charged when the grid load is negative because of PV (PV is not attached to the H1 inverter, but has its own stack of micro-inverters, so everything is AC-coupled), instead I get (unwanted ...
