Only 1 inverter ( ignore Tesla ) Need someone else’s input ! . Yes kwH whatever

Installer says … My SE DC battery can charge at the highest rate my pv can generate . ( it’s effectively a solar buffer ) So in theory an empty SE battery . Sunny day , pv generation at 7kw . Battery charges - great ! Then battery full . pv generation still 7kw . Yet only 3.66 will either go to house load and/or grid … Why ? Inverter limit of 3.66 applies to current “ going through it “ I.e not just exported but house load ????

Ok . Don’t worry about my non standard setup . pv array 10kw . Pv generation 10kw inverter export limit 3.66 Should 6.33kw go to house ? ( assuming there’s a load )

My setup is non standard . There are mis understandings on the installers part and mine . It works - but I’m confused by the inverter … Suppose you have a 10kw pv array and it is generating 10kw Inverter output is limited to 3.68 . My belief was in this scenario ( assume house load zero ) that 3.68 would go to the grid and rest “ lost “ If 10kw pv generated and a Tesla battery ( charge rate 3.66kw ) . Then shouldn’t 3.66 go to grid and 3.66 go to battery ? Is the inverter limit of 3.68 for *everytjing* I.e that’s the most it can deal with regardless of where it is going ? Hope that question makes sense !

Nah . Don’t do that . Suspended ceiling means you can access all the f ups !

Ah right . My bathroom is finished yes ! - is yours ? 🤔

10 tubes of lube 🙄🙄🙄🙄

How does your cat get out ?

Define finished ….. 🙄🙄🙄🫤

@Thorfun you’re having suspended ceiling in basement yes ? ( sure you said that ) . So no worries about access if anything does f up . Also remember @Nickfromwales hadn’t built a (expletive deleted)ing house on his own and I have - so ; WORD !

I don’t care about my neighbors 😊

Got ya Those new DNO rules only seem to apply to new connections forcing infrastructure upgrades . So I’m out of luck there . But ! I’m so far from my sub station apparently ( adding to the issues ) that I guess in time a new development could appear forcing the necessary upgrade .

So the issue is raised voltage due to another ac inverter . No device that can limit this ?

Yeah . So it’s an infrastructure upgrade required . So dno’s responsibility to do now ?

Somethings not right . Heres the original reason for refusal I’��m afraid we are unable to permit the installation of any additional generation at this property. The customer already has a significant export capacity (8.6kW) and therefore any additions to this would result in their volts (and those of their neighbours) being extremely high and certainly outside of statutory limits. Whilst in this instance the customer is on a lightly loaded LV main, fairly remote from the substation (both of which contribute to volt rise), I am yet to see an application of this size which can be permitted. Having almost 14kW of generator capacity on a single phase supply will always result in very high volts due to the imbalance created on the three phase network therefore is unlikely to be approved in any scenario.

No . Right in a suburban area ! . DNO just wouldn’t allow due to infrastructure upgrades required ( apparently ) . But now ! - now I got them 😁

Yeah I’m not convinced. But in theory DNO’s are going to have more difficulty rejecting ( or limiting ) things . I’m certainly looking into it . I *presume* also I could apply to increase by export limit of 3.66kwh . They gave me a merry dance last time - so will see what they say ….

I see since April 1st DNO rule changes have been applied that infrastructure improvements may not be passed directly onto the customer https://ukpowersolutions.co.uk/2023/02/14/changes-to-electricity-connection-charges/ This means that maybe I can have another PW but with an export limit 😊 ; makes octopus flux look even better …

Sorry @Nickfromwales your posts don’t seem to be appearing correctly. Wonder if I can do what you’ve done but with other 4 letter words ? 🤔

🙄🙄🙄

It’s Amazon ; can always return 👍

It does limit local purchasing options !

Admittedly you can’t do this trick too many times . The other ‘cheat’ is receive say 30 lengths of timber . Call BM to complain ; that some are bent and unusable . They say if you send photos no need to return them and they’ll send out new . So just take 10 photos of the one bent one !

Yes . Exactly that . I don’t know the total loads as I will undoubtedly add things over time . Might punt on @ProDave ‘s Amazon link . I have got a few cat5’s where I want them - but never enough - so trying to plan for future expansion.
