New V2G trialist and my installation experience - how much have trialists actually saved on bills from this setup?

Wow, Milkybars are on you then! 

Well done team, @Ash_OVO @Bobby_OVO pass this on to your engineers if you can!

@Jequinlan did you know we have a Kaluza ‘Ask me anything (AMA)’ topic event live right now? Get your questions in to two product managers if you haven’t already here

This is how July ended! Its strange it doesnt export more given my energy usage! It sits most of the day fully charged.

@Jequinlan- can I just ask you to expand on your comment about asking UKPN to “adjust the voltage at the local transformer”?

As you’re in a very small village, I guess not too many people were affected by this. But a feed from a typical ground-based sub-station transformer would supply power to around 120-170 homes.

The guideline voltage for GB is 230v -6% / +10%, which equates to 216-253v.

What was your voltage before and after adjustment?

How wide was the voltage fluctuation over a typical 24hrs (or was this not monitored)?

Was it the Kaluza engineers who diagnosed the issue?

Hi. So.. i have some geeky graphs to accompany this. Basically the kaluza team identified my matte device connected to the v2g was tripping at 255V (above 253 limit) regularly. UKPN then sent 2 engineers on 2 occasions to measure using kit, then, decided as it looked high at most times, to install a monitor for nearly a week (visit 3), removing it (visit 4) and downloading the data which took measurements every few milliseconds,  it was clear the kaluza team were spot on. The substation when they checked was unusually on "tap3" and most of the uks substations apparently are on "tap2" this sets voltage apparently to the premises  

Thankfully its now all awesome. 

Images attached showing it really was happening far too often!!

@Jequinlan My 4 engineers seems a light touch now compared to your 8 

Has anyone had any issues with the kaluza app not updating scheduling times or charge range amendments? The only thing I can actually get the app to do is Boost, aside from that none of the changes  I make actual stick and the scheduling/range remain as they were when I first set up at the end of July.

Any of you have any experience resolving this?@Tim_OVO @Ash_OVO @Jequinlan 

Thanks

@IbrahimEV Mine (android) has always worked perfectly as an app. I don't know where to set the min and max charge levels on it, but as an app it has been flawless for me...

Hello @Transparent,

Whilst I cannot comment on individual accounts, I can confirm that unfortunately, we are not always able to identify a looped supply just by photographs of the fuse/cutout or even visiting the site. This is for a number of different reasons. Firstly, whilst a supply may be looped, the property could be the last of a set of loops and would, therefore, appear 'unlooped' to anyone looking at it. In addition, the loop may not be accessible in the property. If visiting the site, we can scan the ground to identify the chances of a supply being looped. However, the Distribution Network Operator is best placed to confirm the type of supply. Once we have applied for an EV charge point connection, the DNO will confirm the type of supply and what works can be carried out to proceed with the installation

@IbrahimEV, could you please confirm what browser & device you are using to access the web app? We recommend using Chrome Browser as this has the best compatibility. If you’re still experiencing issues, please clear your Cache/Cookies and log in again. Please note, it can take up to 24 hours for a schedule change to take effect. 

I hope this helps.

I agree @Ash_OVO - I had hoped/expected that you would have access to the DNOs maps. Looped supplies are shown there, so you could see that before the site visit.

However, if you’re actually contacting the DNO anyway, do they clarify the earthing arrangement for that locality at the same time? That’s a subject which has popped up here on the Forum from several householders with V2G chargers.

@D10hul can you think of anyone that’s been effected by this scheduling time amendment issue?

@Mikeyoung ? @jp1 ?

@IbrahimEV @Tim_OVO 

Not really seen the issue, however the most recent update in the app has seen it Lock, well certainly on my phone (iPhone XS) I had to restart the app, this can often happen when trying to make changes, you think they are done but the app has actually froze, best to log out and back in to check the amendments, and of course as ever report to @kaluza
