Powerwall Inverter Efficiency Question

I’ve looked back over the last year and it looks like I lose about 6% of the power coming into my Powerwall 3. I know most inverters have an efficiency curve but I’ve never seen one for the Powerwall.

Usually, in my situation, it starts storing solar when there’s an excess after breakfast time and it’s charged by lunch. This is often when there is only a bit of excess. I’m wondering if it would be best if I hold off charging until around noon when the solar if peaking.

I think I can use the NetZero app to pull this off but I’m wondering if it would be more efficient.

What are your thoughts?
