Getting ready for export using 8kw solis and 16kwh seplos battery

Batpred · 2025-10-19T23:23:41Z

So my plans when installing the 8kw solis and 16kwh seplos battery were not for export, just a protection for blackouts. And a first step to lower electricity expenses as they will only grow when we get an ASHP. Eventually we may add some PV. The install is almost ready. 🙂 Now as ukpowernetworks stated will approve us to do 5kw export, taking the next step while it is all fresh seems simpler. Octopus seems to accept export without MCS (as I had no plan to export now, I never got it from the electricians, not sure if they have it or not). What are people's thoughts in terms of advantage to get the MCS paperwork vs setting up export to the utility operators that do not require it, is there much to gain? And the simplest way to do it. As I have no questions about safety etc, the paper is the value.. 😉

I have an MPAN also, so would be the same process as you.

I just need to decide if it's worth the couple of hundred pounds to get a few pence back for each kWh exported from the battery during the summer.

I would have not got it if it was that tight
