Battery Recent PV and battery install - smart meter readings misaligned

[dburrow2]

Hi all ,

looking for some advice on my recent install of a pv and battery for my domestic property.

I've noticed my smart meter readings tracking higher kWh usage than my read out from the inverter.

I've already had the installers out once to take a look and they are saying the CT clamp is fine and I should contact my energy provider, have done but no resolution from their side.

I've attached some pictures showing my usage Vs a breakdown of my system for a given day. Also from the manual for the inverter and it's polarity to the inverter.

I've also included the CT clamp setup by my meter.

Any advice would be greatly appreciated

thank you
