My apologies @batpred I overlooked that you'd already I identified your DNO as being UKPN.

So you are more likely to be in an area where 5kW export could be permitted.

Even so, the ENA guidelines do not allow the installer to set the export limit using the inverter's inbuilt firmware.
Only Sunsynk products have approval for such operation.

Tesla do too, in their PW3, but that's an all-in-one inverter/battery solution.

 


Samsung 12kW gen6 ASHP with 50L volumiser and all new large radiators. 7.2kWp solar (south facing), Tesla PW3 (13.5kW)
Solar generation completely offsets ASHP usage annually. We no longer burn ~1600L of kerosene annually.

@old_scientist And the Powerwall 2 has the same facility. I am able to export to a somewhat higher limit of ‘No Limit’ according to my installer! I have exported at something over 14 kW with the combined   battery and solar contributions. This I have done a few times when Octopus Energy have encouraged me to do so! Rewards, Toodles.
