Hi,

I have a newly installed 9.5kW battery and have it scheduled to force charge to 100% between 02:00 and 04:59, to take advantage of the off peak rate. This has been working perfectly since installation, but for the last two nights the charge has started at 02:00 and then stopped when the battery has only reached 25%. Has anyone encountered this before? If so, how did you resolve the issue?

Thanks,
Adam

You can configure a target % which will stop the charging at that point. Is it possible that has become inadvertently set/changed ?
Do you run any kind of automation service, or just static timers?

DD I’ve double checked and I have the timed charge set to 100% and the other settings are all still at the default. I am in the process of setting up home assistant, but so far I have only installed the GivTCP add on, I have not started to configure it or set up any automations. I have just uninstalled the add on and will see if that makes a difference tonight.

Dodmeister very unlikely that givtcp installation will have caused the issue, but if you accidentally set one of the control entities in HA then of course it will

Recommend that you change the timed charge % limits in the portal to something else, and then change them back to what you want them to be. The portal holds what it THINKS the values are set to, it doesn’t read them directly from the inverter (only givtcp does as it interacts directly with the inverter) so its possible for the portal and the actual settings to be misaligned
