I wonder if you have now resolved issues. The CT clamp certainly looks to be in the wrong place. Its purpose (I think) is to tell the inverter about power to or from the grid. With it on the consumer unit supply it will only ever give a one-directional reading. Scottish Power offer the SEG...

I have now set the levels at 10% and 15%. Surprisingly the battery now discharges to 11% and stays there overnight without being recharged from the grid. There's some logic to it somewhere!

OK, thanks.

Thank you both for your interest. I don't have any off-peak tariff. I have experimented with the charge and discharge schedule, but its not useful at present. Attached is a typical plot from a recent cloudy day, showing the discharge and recharge from 15 to 20% in purple. There was very little...

Thanks, I meant what you said, I think. I have a new system and noticed via the app. that the battery discharges to 15% during the night (supplying the fridge etc.) then gets charged to 20% by the grid. Maybe one or two cycles of this each night. This seems like a poor set-up given that nothing...

How big should the battery capacity be relative to your daily usage? A bigger battery reduces the amount of charging and discharging, and may have a longer life, but is it worth the extra cost?
