Newbie - P/Wall 2 + 12 Maxeon 375 (all SSW facing) + solarEdge + Tesla Gateway 2 (no EV). Commissioned mid Jan.
I'm interested to know if any Powerwall (PW2) users have actually moved onto FLUX since it went live and what their experience so far is?
Reason being - I don't think (from what I've seen in other forums) that PW2 owners have any control over direct export from their PW2 to grid - at all.
Speaking to Tesla support, their message is - no you can't force export or control if, how or when your PW2 discharges to grid - only your energy supplier and/orTesla can do that.
So unless I'm missing something here - the only way Im allowed to export is when there is excess solar (PV output>(battery demand+home demand)).
My NG commissioning doc states - '3.68kW PV and battery storage 5kW set to zero export'. I asked my installer about this and they confirmed that any export to grid will come only from solar excess and that at present the battery can never discharge to grid, and peak solar export to grid is inverter-limited to 3.68kW, but peak battery output (for home consumption only) is 5kW continuous.
I've emailed Octopus to see what their views are and I'm still waiting for a reply.
So for me, it seems that even with my PW2 100% charged and ready to rock its 13.5kWh, and 0kW home usage, I still can't take advantage of FLUX peak export rates unless the sun is shining....
At the moment I'm on Octopus Flexible Tariff (flat rate), so on sunny Saturday the PW2 hit 100% soon after lunch, after which the Tesla app began reporting up to 3.2kW export to grid - my good deed for the day....
I'm hoping to get going with FLUX soon - but obviously I'm aiming to optimise avoided costs of import + export earnings so I can reduce the payback period (currently 12 years) for what has been a pretty expensive investment!
Apologies if I've missed something obvious (should have gone to SpecSavers comments aside - I'm stuck with Tesla now!).
