Tesla have approved a 5kWh export rate from our Powerwall, based upon the G99 certification from DNO. I have an export MPAN too but Octopus sticking to their guns, MCS certificate or £250 admin fee to be considered for export! We didn't get an MCS certificate for our Powerwall, installer tells me t...

Regarding the 8kWh figure, obviously I haven't seen the reference yet, but that sounds about right for domestic leccy (not total energy, nor for BEV's) at around 3,000kWh pa. I think the UK household average has been steadily falling for over a decade. I recall 3,600kWh, and 3,200kWh as averages, b...

Not sure if this is helpful, but we moved the zappi upstream of the battery (Powerwall in our case) so its now never seen as a house load. Moved the CT too. Prevents drain when Intelligent Octopus stick in some cheap slots outside of the normal 23:30 to 05:30 times. Hi Niko. I also have got a Power...

May fail the cheap criteria but a circa 2017 Tesla Model X with the free Supercharging for life SO1 option? How far from a Tesla Supercharger are you? :whistle: Vanishingly few TMXs sold in the UK had free Supercharging, of those that did most would have had it stripped out when being PX’d at Tesla...

So as we normally use nothing at those times as we are still on battery, and we can't export as Powerwall is set to never export and we don't get paid for solar export as we don't have MCS certificate, we will get nothing? Oh, good :head-bang: Can you not get an MCS certificate, then you can force ...

I changed my tune from solar and batteries to just battery if you need to do it in stages.

Correctly sized battery and good ToU tariff and you could probably get away with running your house on the overnight rate only
