the silly idea i had last night

can you have 2 different meters from different suppliers?

i have 3 phase so could split it

If i could get another supplier to fit a meter and go for a very cheap rate tariff -even if night only say 15p or less

use that to charge battery when it can -- then i would get a my good export rate through current octopus flux deal ?

where i get 21p at low rate and 27.6 at high rate

I believe you could but any savings from a better tariff would likely be offset with the double standing charges and cost of installation.

Better to spend your time optimising what you have, including load shifting.

Two standing charges as well, you can good export rates via Agile outgoing as well. Good imports via various tariffs, with one meter, add Axle to mix for export, which you are not allowed to do with Flux.

Currently on Cosy at 14p 3x a times and todays export rates on Agile get upto about 22p, other days higher

Do Predbat or similar to manage your in and out electricity and demand usage.

Importing on one phase then trying to export on another phase could lead to a bit of a bang.

Would need to have some reliable switching of the battery between phases and youd likely need to speak to your DNO to get a second MPAN

Yeah, I was toying for a while with having 3P in-house (loads of PV and meant I could buy a bigger 3P inverter) but on a house with a single phase supply. Obvs only 1P of in-house could be linked to the incoming supply. After a while of mulling it over I just concluded that it would fry the DNO’s brain plus any spark I had near it as too unconventional to contemplate. (I once had enormous trouble getting a 3P meter swapped out for a new smart one - the DNO at that time couldn’t compute ‘3P in a flat’ even though it was installed that way in the 90s. Took 4 visits from the DNO from memory.) While your scheme may work technically, I figure no DNO staff or systems or your own sparks would be able to cope with it intellectually.

Have to say I was thinking John's idea was much simpler.

Install solar/battery on one supply. Have another with a better rate for high consumption. Have a transfer switch for the heavy loads and switch over as appropriate (or even just wire some heavy loads that will almost always draw from the grid to one and everything else on the other).

looked at that and the octopus intelligent seems best all round

import +export for most of the day with a high rate between 4 +7 at night

they pay and charge same coming or going

and its done automatically by them

then i have the axle energy as well so they pay £1 a unit when they want it

Octopus intelligent and axle are a no go, as it's not allowed, by Axle or Octopus, your API from Octopus would stop it working.
