This may seem like a really stupid question that I'm over thinking.

I have a tesla pw3 with one expansion and 9kwp split evenly East/West with 4.5Kw export limit.

Our new Octopus fixed rate has a night rate of 8p per kwh and an export of 12p per kwh.

Taking into account exchange losses of ac-dc-ac, does it still make it worthwhile to import at night rate and export all my solar during the day? Or to self consume and only export the surplus?

Thanks
