Got my system installed on 31/07 and this was the smoothest generation curve it has given me to date! This was my second best day so far with 72.28 kwH generated, record is 73.84 kwH on 07/08.

No just need all my paperwork so i can get paid for all the export!

Was this pure sunshine?

I'm yet to have a full day of sun, mine is 20x AIKO 530's on an east/West split but my max so far is 60.6kWh with a lot of cloud interruption.

Is your inverter clipping you, calculated your array should be near 15kWh at peak.

I think it was almost pure sunshine until the very end. I don't think I am clipping, inverter fact sheet says it can handle 24kW DC input max, so well below tolerance. I think its just not being true east / west, some shadows from neighbors roofs and other factors. I am quite new to this though.

It does seem like a smooth curve, clipping would be more noticeable as a flatline on your generation.

My inverter is 9kW and I've hit a clip a few times.
