I think I've been told some porkies, some mis-information and indeed mix that up with my lack of understanding creates a rubbish brain soup. 3 phase solves the issues also might not work out that much more expensive. I was told SE would be a more expensive install than simply strapping another PW on. So the 3 phase cost might effectively lessen again if going down the PW route... I just want lots of batteries so I can sell my electric to my neighbours at vastly inflated rates! ?

Absolutely. My assumption is she's just looked at a google earth view and done street to door. As I have underground complex and driveway infront and assuming cable can run over these the 'dig' length can be reduced substantially...

Yeah probably me mis-understanding. I guess I should say my total number of inverters connected to the grid can not exceed 8kw of export. I think that's right.....

Yeah . We all know about kryton given all the Tesla goodies for free .

Had a brilliant phoncecall with DNO. Now I understand. The issue is I have 2 inverters that can export . PV and the Tesla PW one. So my theoretical maximum output is 8kw. I'm simply not allowed anymore. So.... Options are a SE battery or similar which goes into the PV inverter i.e. DNO don't care. Or maybe back looking at 3 phase. I went back to the DNO for a 3 phase install estimate. I have no detail ( presume length of run is a cost ) so *assume* she did street to front door ( but there are a few tricks I can do there ) and she said 6k inc vat. Assume VAT is 20% on these things so can knock that off. Also can a mains cable i.e. the 3 phase be above ground? ( obviously in some armoured conduit ). I can't drill into underground mega complex but I can take a cable across the front and conveniently through an existing hole in the above ground structure that practically everything currently runs through. I assume 3 phase solves all my issues. I can just stick a new PW2 on a different phase. Indeed I could have 3 PW2 - could I not? She knew of no-one with 2 PW - well love, POCSTER is now in town!

End contract with builder early to solve his liability issue . You then take out insurance to live on site in an incomplete dwelling . This type of insurance is more expensive I have it and I think @ProDave does also . All problems solved ! I did it this way also because I didn’t fancy bankruptcy either ?

As I’m the builder and the last conversation I had with bco was asking when they needed to come and inspect next . They replied “ when finished “ . Not finished , so …….. ?

I doubt it . Surely I could tell …?

3 phase was ( from memory ) 10k

So nothing to do with import / export ? . Simply the amount I *could* generate ???

This is what’s confusing me . If my export is capped at 3.6kw regardless of how many batteries I have that’s fine . Spoke to various installers , 10 different answers . Decided to call my DNO directly . Get it straight from the horses mouth tomorrow…

Yes . I’m not trying to be greedy lol . In reality zero export would be fine - but in summer might be a bummer - but perhaps that is just tough …. Trying to use summer sun to offset winter costs . Still confused anyway . Afaik I’m only allowed 1 inverter . Tesla has an inverter and SE would require one also . Called SE - some call centre somewhere; he knew less than me !

The more questions I ask the more confused I get “ It is to do with the voltage increases - without export limitation we are only allowed a 1% increase, with export limitation we are allowed a 2.5% increase. In this instance, the voltage rise would be above 2.5% in both cases, so export limitation is not an option.“ I believe the issue is that an export limitation triggered by DNO can take upto 5 seconds to action ….

As you say , at least you have errors reported …. A temperamental boiler reporting no error codes is worse . Valiant engineers in my experience of using them for decades are usually pretty good .

Ummmmmmm

? ummmmm , still not done anything with this yet - on my to do list …

I’ve still learnt nothing

DNO unsurprisingly refused my request . But potential installer says solarEdge can. Charge from grid . Wtf ! . New installer says DNO don’t care about how much I draw it’s how much I export . So I’m confused again . Why can’t I just have another PW2 and have a limiter on my export …

I used 50mm 'cause I'm special.

Shouldn’t be using it there

He only has tiny marbles that’s for sure

Don’t know what you mean

Nah . I’ve just had a 45 minute online argument with Deliveroo and then had to go to the restaurant myself . So I’m in no mood for prisoners , executions all the way .

I love you again Yeah @Onoff I’m with @Big Jimbo on this it looks (expletive deleted)ing shit ?

Wtf !
