At the moment I'm staying on Flux, I will probably turn up my charging at some point, so the batteries start the day full, rather than at 80% as they currently do, which on bad days will give me more to force export at peak.That's still decent, what are you going to do over Winter? Will Flux still work out fairly cost neutral given your larger capacity for storage and generation?
I've not done the sums, so not really sure, and I'm sorely tempted to add more panels, but that would require planning permission for a solar veranda.
