I have had new install in January 2026 and learning the process, graphs and all. It's so confusing.

Could someone please help me understand? The graph shows that I have used 47 KW today? That's way easy too high?

I have Sunday half price so had battery on charge so understand would have done 10kw but then I used that plus 37 from Grid too?

My annual consumption has been around 3k for few years which makes around 9-10 me per day hence confusing. Especially when for heating I have had central heating not even electric heating.

You seem to have turned off some things on the graph, but is the battery 24kWhrs?

You actually used, as in pulled from the grid 37.90kWh. The battery charged 10.90kWh, this value is a literal "how much energy was added" this can be from grid or from your solar.

If you look during the early hours, you was pulling a near constant 3kW until near 9am. You can see a power spike to around 7kW just after 8am, most likely putting kettle on.

At 12pm when you get your cheap rate, you are using 9kW give or take some house load, to fill the battery up (EP12?) and it holds 100% SoC on your battery until 4pm, when it begins to supply the house loads.


Now, I suggest you try and discover what is using the power during the night, as this is adding up (9hrs at almost a 3kW load is 27kWh's) Do you have a hot tub or something like that?

Also, what often happens is when people get solar, they can increase their usage, so your annual 3,000 kWh will most likely be much higher going forward.


I hope you can find your big power drain and let us know.
