You can see on this where I have manually reset the system to grid and solar on the app (for example at 0706) and where you have set it to off (0657) at the end of a charge cycle. This switching it off is relatively new (or I’ve just noticed it following a fail to charge the other day on both systems I have). As the OP says on the app it is “grid and solar” on the web portal it is “AC charge enable”
Having seen it charge last night and still do the switch I am not sure it matters now, but I had, perhaps wrongly, assumed that that was the cause of the failure to charge on either system a couple of nights ago in my morning cheap rate window. From the logs I can see you are switching it to solar only (ie ac charge off) at the end of a charging window but setting it to start charging when required
