Personal opinion to consider with caution only.
I see what you're trying to do, or why, but you can appreciate, I'm sure, that it's not precise, because your East/West configuration pulls your production earlier and later in the day, and flattens the peak production.
Perhaps if you do that, try to experiment with finding the peak forecasted value if you face all the panels East, and/or all the panels West. And then de-rate your Max Solar PV value in the SA setup, depending on the expected lower peak power generation that you see in those alternative forecasts. It could be for argument's sake that you say you've got 10% less PV, or 9000W estimated.
Most days the forecast won't matter much, if your battery is charged by 10am in the morning.
