Any way of setting a Solis inverter to not discharge to the house so I can export to the grid?

This is just an idea so feel free to shoot it down but during the darkest days my PV is probably less than 10% of my usage so I was thinking of putting the batteries to good use by utilising Octopus Agile. Looking at the rates they pay up to 60p/kw at peak times to export with a flat import rate of 33p. Surely it's possible to charge the batteries to capacity and then export at 16.30 to gain some profit. Getting nearly 30p/kWh.

The only problem I can think of is once the batteries have charged the house will start to use the energy before it get's to the peak time when you are ready to export. Is there any way to keep the battery full and prioritise the grid?

Yes, change the mode on the inverter (under advanced settings) to Feed-in Priority. This will ignore the battery and will export (less house consumption).

Lucky you! If we had Octopus over here, my electricity bill for the year would be negative 😎
