Hi,

Can you tell me please is the Liberty 100 Smart Meter you fitted a 'dual' or even 'triple' rate meter?

If it is can you tell what your dual rate tariff is please. I ask as I have just purchased an electric car and it will probably make sense to charge at a lower rate at night.


Many thanks

John 🙂

Hi @JohnB,

The Liberty 100 meter can function as a two-rate meter, but not three rate. This particular model of meter is designed to be connected to domestic supply with no additional connections (like storage heaters).

We can also install a Liberty 110 meter which is designed for electricity supplies that have a separate connection for storage heaters. This model of meter has an extra 'port' or 'terminal' to link up to them. These models can also function as single or dual rate, which we can change remotely.

Hope this helps,
Nancy

We have recently installed a Tesla Powerwall with a back up gateway for our solary array and are now enjoying electricity charges of £0.02 + daily standing charge. Looking forward to when these summer sunny days are a thing of the past we will need to be able to buy low cost off peak electricity to charge the battery BUT I am finding it a tad difficult to get an answer to (A) can ny OVO installed smart metre manage say Economy 7 and if so what are the rates and times. If anyone has already done this then I would be pleased to hear how it went. Incidentally we receive FITs payments so are not presently interested in selling our exports.

Hi @Stargazer8t6 and thanks for posting :)

 

Interesting to hear about your Powerwall set up! It would be great to have a bit more info this: what’s it been since install? How was the fitting? Getting a topic posted on this would be super handy for any other users thinking about a purchase! FYI @Gibbsy (they posted a topic on the Powerwall here as well

 

Anyway, your query: have a look at the ‘best answer’ for more info, but in short the SMETS1 meters can be changed to a 2-rate economy 7 set up remotely! Reach out to our support team to get this done. We’re on FacebookTwitter and email: hello@ovoenergy.com

Thanks Tim, Already been in touch and they have confirmed my metre can be remotely reconfigured when I want it done - at end of present contract in Sept probably. Thanks again

I had a Powerwall 11 installed on 21st May 2020 with back up Gateway. My specification was to be able to have a self-powered home. I.e. I didn’t want to buy any grid electricity at all, or at least reduce my dependency on Grid supplied energy.

My solar array is some 6 years old and performs very well but the inverter is grid connected such that if there is a grid power failure/outage I have no power in the home – so not even the gas boiler will work! The Tesla back up gate way keeps the house energised even if the grid is down. Solar power continues and or the Powerwall depending on the time of day.

The installation was straight forward and was completed in 2 days. Things to look out for if considering a Tesla installation. Get at least three quotes and make sure any installer is Tesla accredited – Tesla won’t allow non accredited installers near their kit. The gateway needs to be connected to the internet - ideally three different ways. It comes with a SIM for remote monitoring by Tesla support but they require it also to be connected by a direct ether net connection and WI-FI.

The concern is that if your router is changed and the connection is not hard wired then you will not be able to use the APP to control the system. The Tesla APP allows you to monitor in real time how much energy is being produced and where it is being used or exported – very simple and straight forward – ok for smart phones as well as android tablets.

The result is that from 21st May 2020, I have only spent £0.02 per day on grid electricity plus of course the all-important daily standing charge.

BUT – on a poor day with low light the one Powerwall installation can become almost exhausted. I have set the back-up limit at 5% (in case of a grid outage) after which the gateway will allow grid energy through to power the home.

Now for the complicate bit – do I stay on my one tariff rate day and night – or switch to say economy 7?

Staying as I am, will mean paying more for charging the battery off peak, assuming that on most days I will have sufficient power in the battery to power the house during the day and evening? BUT switching to economy 7 and being caught out on occasions of poor light in the day may result in having to use grid power at an expensive time.

Experience to date suggests that our present profile of power usage allows the solar/battery combination to get us through the most trying days until late evening and as there has been so much sunlight through until charging can take place from the solar array. In winter I would need to charge off peak at night to be ready for yet another dull day.

I want to stick with OVO – been with them for 6 or so years and I have never experienced a more cooperative and supportive utility provider in 60 years of desperate struggles – so my instinct at this time is I will switch to economy 7 at the end of my current contract and tweak our usage through the winter such as to only use off peak power from the grid.

Hope all this helps someone and if anyone needs further info please let me know.
