Actually it isn’t.. it’s a fallacy as the grid frequency is driving your inverter phasing so if you hit the main isolator on your grid connection the lights will go out ....

It certainly will Also the battery is currently set to charge only off pv . Was 5% this morning ( I set that as the minimum) - currently at 7% . Not a particularly sunny day . I wonder what could be happening??? ? Link to comment Share on other sites More sharing options...
Pocster Posted October 20, 2020 Author Share Posted October 20, 2020 I think you guys should *perhaps* google other people’s bills with a combination of pw , EV , pv - surprisingly it does work ..... ffs ! . Jealous (expletive deleted)s - tempted to buy a Tesla car as that will increase the bitching for sure . Though a 50k car is a good investment for sure ( no offence to anyone that has bought one ) . Once I get a proper accurate bill I’ll post here so we can all pick apart . 1 Link to comment Share on other sites More sharing options...

Are you planning to get a battery and or PV? I’ve watched a guys posts on an octopus forum about his EV with PW . He’s obviously got ocd and is obsessed with getting it charged as cheap as possible . I believe his record is £1.64 for a full charge ; so 250 ish miles ! Link to comment Share on other sites More sharing options...

I'm seriously leaning towards just filling the roof! (using man-maths) just think of the money I can save by not having the roof tiled. ? 3 minutes ago, pocster said: I’ve watched a guys posts on an octopus forum about his EV with PW .

Pocster Posted October 20, 2020 Author Share Posted October 20, 2020 I think some gits on here must ‘drive’ a horse and cart ( cheaper than a car ) back to their steam powered shack - coals good to use yeah ? Only 1 planet Earth . Only took mankind a few hundred years to screw it . Time we all did a bit more than just separate glass from plastic with our recycling .

You got a mega farm ? ha ha....no, just a new 3-phase connection going in. it was about £20 more expensive to get 3-phase over single-phase. so it made it a bit of a no-brainer really. 1 Link to comment Share on other sites More sharing options...

Tesla PW2 supports battery backup failover during grid outage, and I understand it will adjust the frequency dynamically to lure the PV inverter into increasing/decreasing production according to needs. So it depends how this one was connected up. 1 Link to comment Share on other sites More sharing options...

But I still don’t get how you were allowed 3 phase on a normal domestic property ? Even if I wanted it at install it was mega money !! . I asked for 3-phase and single-phase to be priced up as I have one EV already and plan to swap the wife's gas guzzler for another at some point in the future. plus she does a lot of needle work and has overlockers, embroidery machines, sewing machines etc running when working which could eventually be upgraded to larger machines. so when the DNO said the difference was about £20 between the two it was an easy decision to future proof our electricity connection. one of the most expensive parts to our new electricity connection will be the road closure to lay the cable underground. it's only a single track road so the local council charge a sh*t load to close the road. my challenge is to get the electricity company, Openreach and the water company to do the work at the same time so I only have to pay for one road closure. that should be fun. although, I've not paid or finalised the order yet so I hope it's still available when I finally get around to doing so! but I'm pretty sure no one else around here is putting in a new electricity supply so I'm sure the capacity will still be there in a month or two. 1 Link to comment Share on other sites More sharing options...

What changes are required to go from single phase to 3 phase ? . I’m guessing complete re wire from street to property??? ? Link to comment Share on other sites More sharing options...
