I have my on-grid AND off-grid cut-off SoC (%) set to 10%. When that threshold is reached, the gridboss/flexbosses correctly cut me over to using grid power. So far so good. As you can see from the image below, however, the grid is also slightly charging the battery (and I don't understand why). This raises the battery to 11%, which cuts me back over to battery for a few minutes until 10% and then I enter into this loop of cutting on and off the grid every few minutes.
In case it matters, my battery setup is 6 indoor batteries connected to an external busbar with each inverter sharing the bank.
here are the settings on my "main" inverter (there are 2 in parallel):
How do I change my configuration so that the inverters will not charge the batteries when they first cut over to grid power?

And here is a follow-up question. If what is happening here is that the solar panels, with their tiny charge in this rain storm, are what is charging the battery, then is there a setting I can choose to say: "once cut over to the grid, do not cut back to batteries until they are at {settable value} SoC %"?
