Have solar, economy 7 and battery - day time reading clocking at night?

Hi so I have has solar panels fitted last October 2022. I have 2 tariffs a day time tariff and an economy tariff that kicks in from midnight until 7am. This is when my battery recharged ready to work from 7pm until the solar panels take over. However I take a reading every night before I go to bed and one again as soon as I wake up. My economy rate goes up in the night by about 4/5kw but my problem is every night my day time rate moves up 10kw. Nobody knows the answer as to why and the electricity company do not seem interested. Can anybody help me I now have about 6 months of data and can’t get a resolution. Can anybody please help me

If you think your day and night readings aren’t clocking the right way round you can check this yourself by completing a simple ‘load test’. If the results show the readings are the wrong way round you’ll need to send the results to our Support Team.

I was just wondering about the solar falsely increasing your reading. 
If you add the Loop reading to your smart meter reading for August you get almost 800kwh!

If it was me, I’d be tempted to switch off my PV feed for a few days to see if that affected your meter reading. 
I still think that your solar is adding to your usage somehow rather than reducing it

    No problem. It’s difficult to tell but I think your CT (white clamp) might be pointing the wrong way. 

    If my assumption is correct, the arrow on the CT should be pointing away from your meter - it look like it’s pointing towards it. 
    Another assumption is that the CT is for your solar PV inverter.
    There is a ‘clip’ on the bottom of the CT which opens it. Then it can be unclipped and replaced the other way around. You may want some more information to double check but if it is pointing the wrong way, your solar system will be getting the wrong reading for it to operate correctly

     

    Here’s a video about the CT position

      Here is another thing so I downloaded loop energy and connected it to my smart meter and the reading are so far apart. In August 2023 the loop app says I used 262 kWh of energy my smart meter reading says I used 532 KWH and that is what I got billed for. Have checked every month and the readings are miles apart

      Do you have any separate readings for your solar and battery system?

        So my graph is showing I generated 800k/WH in August so with the 532 I got from the grid that’s 1332k/WH in August I can’t believe that’s correct in the middle of summer
