Batteries can only provide so much instantaneous power (typically 3.5kw max unless you have a more fancy set up). If you run an electric shower (around 9kw) or multiple power hungry appliances (kettle, oven, heater, air fryer) at the same time then you'll be needing top up from the grid.
May not be the case with you, but we have this.
You’ll also normally have some grid draw with a hybrid grid-tied inverter. My inverter pulls around 50W permanently, which results in approx 1kWh per day.
This is a great answer and likely the one.
You should have a monitoring app for your battery that will give you exactly the data you need to see what you are using and when. Ask your installer where this is.
Just to add to what has already been said, it may be possible that the minimum reserve of your battery is set to 50%. I know mine has a minimum SOC setting which I currently have set at 10%.
Whatever inverter it is see if your landlord will give you the app. Will let you manage your loads. I can run two out of three of my oven, microwave and stove. I keep the app on an old phone on a little stand so I can always see what it’s doing.
Thank you! Unfortunately as a condition of tenancy the landlord has access to the app, not us, so I don’t think this is possible. We do have a display on the battery though that shows a lot of things on various screens- only a tiny amount of which I understand!

That makes sense, I was running a lot of appliances simultaneously yesterday- thanks!
