Interesting concept, but it looks to be limited to the same inverter brands as the smart Octopus control tariffs, which currently doesn't include Sunsynk systems.

It also doesn't require a change of supplier, so appears to be additional to the export rates already being paid by your existing supplier, which would make it something of a no-brainer to sign up for, if eligible, and you were happy to relinquish control in this way.

I'd be interested if and when my inverter became compatible.

@toodles I watched with interest too.

My first thoughts was that it would be a good addition to run alongside/in addition to Cosy in winter (I still plan to run IOF in summer). Even in a worse case scenario you'd get £1 + 12p per kWh for export and then have to draw from the grid at 30p or peak rate 45p, rather than just consuming your own battery. That seems like a can't lose deal that can only enhance the net financial position.

The obvious down side is you have no idea how many events there will be per week/month, so have no way to evaluate against other tariffs such as IOF. In summer I still prefer IOF, and knowing how much I'm going to generate in export each month. Getting an average 25-26p per kWh for ALL export on IOF outweighs 12p SEG and an additional £1/kWh on a small amount of export for me. This tariff (Axle) would also favour those with unlimited export, who can maybe export 10kW in a one hour window as I'm guessing most events will only last 1h (that seemed to be in implication). Obviously if your export rate is limited, this will limit earnings potential of each event and all other export is just paid at standard SEG rates.

For my own usage, I estimate IOF will net me an additional £370 during the 6 months April to Sept compared to Cosy+SEG, so even if I could average 5kW export per 1h event, I'd need 3 events every week exporting 5kW per event to match IOF.

Solar generation completely offsets ASHP usage annually. We no longer burn ~1600L of kerosene annually.
