I'll leave it for now. AFAIK PW can now export at 8.6 Of course this wasn't what I asked ; I asked for 5. So if it blows up it's Tesla fault

I emailed Tesla explaining that my PW limit is incorrect and that my total inc PV is 8.6 ; so PW needs to be 5Kw. Got a reply today that it's all be changed. Indeed it has. They've set my PW to be able to export at 8.6!!! Wonder what DNO will think if they knew ! 😮😎

No

Yeah I know I could have 3 batteries. It’s splitting the pv load between them is my question .

And it’s not (expletive deleted)ing random ! . I’m trying to save a tiny part of the planet using : limited knowledge technological restrictions dno restrictions limited knowledge oh and limited knowledge I do better on pornhub as I have more knowledge in that field

Yeah - I’ve been on another forum ( not pornhub ) and apparently it is possible ; need to talk to my installer once they’ve calmed down …

Ffs ! You’ve got ufh , boiler boxing , gobble doorbell to finish ! - I give you another proper job and you turn me away !

Oh sorry @Nickfromwales you’ve obviously been cut out the loop on that one . As Netflix or man sold it to me … ”forget breaking bad “ ” Pocsters house of misery and torture “ ( a Netflix exclusive )

So is it cheaper to install ?

I will . Still waiting on that lucrative Netflix contract to come through

Just remember that my job is to provide content - no matter how benign .

I deliberately did this as a separate thread as it’s non specific to my setup and avoids the back story . Thought it was simpler this way

Think now I want more PV - but have run out of roof space . Perhaps foldable PV that opens up on my front garden and folds away when it’s in the way . More PV , more storage , more export ( though I haven’t and can’t reach that yet ) . Sounds like a project for @Onoff

Yeah ; it’s just how much can they be exceeded ??

It’s been suggested on a better forum 😁; this is possible . Its unclear if it requires another inverter . Also potentially if both SE batteries were charging and Tesla battery charging and EV charging and house load might push me over my 80A fuse . So fuse requires an upgrade ? - that a DNO issue ??

Oooooooo - apart from Google telling me it’s a “ North American “ thing ; no one knows ! 😎😁🧸

My SE battery max charge rate is 5kwh . Is it possible to have 2 SE batteries that ‘share’ the pv input ? . So in theory ( with a large enough pv array ) could charge at 5kw each simultaneously? To achieve this is it an inverter issue/ config ; a “ how it’s all wired up “ issue , or not possible ?

Actually witnessed 5.9kw today . Makes me wonder what the true ‘maximum ‘ is …

Oh yes . Me adding another PowerWall ( for storage not generation ) causes problems for my DNO . The infrastructure can’t cope . Ultimately ( as the new rules have been introduced) the DNO is obligated to update infrastructure for new developments. Easier at National / local level than nano - of course it is . But we can’t really afford to all wait .

So it shouldn’t be government and single installs like mine don’t contribute enough ? Reminds me of my planning feedback “ what’s the point of a single build it doesn’t contribute to housing stock “ . What a prik I thought . It contributes 1 . It’s not THE answer to housing but it contributes- same argument with pv etc. Do it ; don’t do it . Someone has to do something. Doing nothing is the easiest and worse non solution - but we know the majority will do that .

Until government does massive projects to supply zero carbon energy ( which could take decades ) its down to people to take what responsibility they can for their consumption and pollution

Agree with everything said Only 1 planet earth …

How many times must I have this conversation. Is it worth it ? No one notice we need to aim for zero carbon for sake of society and the planet ? ROI for me ( I bought pw and 4K pv array ) a good few years ago when they were less expensive. I estimate ( inc newer pv and se battery ) around 7 yrs . Batteries warranty is 10 yrs . Pv life span around 20 yrs . Please don’t mention “ inverter breaks down , optimiser fails etc etc “ . Yes of course it’s possible - just as much as boiler breaks down . As a LL I have modern boilers - not 1 year goes by without a repair on one . if I buy an 60k Tesla motor no one’s says a thing . If I then charge it off my PV everyone thinks it’s wonderful . That’s a very expensive battery !! - but with the additional benefit of wheels . Roi on that ? Is it worth 50k to go from A to B and save a few pence on charging ? That depends on the owners view . On size does not fit all . If it were possible I’d have another PW but DNO won’t allow it ( then I’d look at flux ) . Tempted by another SE battery though now that all the caveats are understood.

An electric bill ( heating inc and low mileage EV ) of zero a year makes it worth it 😎

Yeah , so ?
