Can I install an internal Electric Vehicle (EV) charger inside my garage (with an external connection)?
Hi,I’m getting an EV home charger installed soon (untethehered) and I’m looking at where to place it. Ideally, I want it inside the garage rather than outside on public view. This causes a little headscratching as to how to actually use the charging cable. What I have ‘dreamt up’ is shown below:Charger is on the wall inside the garage There will be 2 Type 2 cables available to plug-in (not at the same time) One cable will exit the left hand side wall The other will, after routing the cable, exit the right hand side wall On the outside I want to fit a ‘port’ (similar to what is pictured - although I used a photo editor to make it) - which I’d like to be a small unit that is very unobtrusive I know that I’ll have to go into the garage to plug in the correct cable (left side/right side) but I would rather do that than have the wall charger itself on just one side externally. This way I have options on which side to use depending on whether we have visitors/another EV in a year or 2. My q
Hi, I get delivery of an EV in March and got my EV charger installed (Easee One) last week. I’m like most members are on a Standard variable rate. I see that the OVO EV package requires a specific charger which I didn’t realise. The question is can can I switch to an EV tariff using my Easee One and would it be cost efficient or should I stick to the standard variable? I do around 700-1000 miles a month, mostly local so will charge every so often but want to charge at the cheapest possible rate and don’t mind charging off-peak.
Recommended settings for efficient heating and hot water with a heat pump? How to reduce energy use.
HiWe had our installation in July and haven’t paid much attention really, water’s hot, love the EcoDan, delighted with everything.And then...We’ve just had our first month’s electricity bill since having the heating on which has focused our minds. If I’m honest, we haven’t got our heads around this at all. Now we want to. We’re reading the manual and up and down to the loft, but have no idea what we’re doing.I’ve just taken readings and calculated our COP is 2.18. I have no idea what that means really other than, based on reading these threads, it’s not great.Our hot water, until a few minutes ago, was set to apparently heat up on demand, there were no timings set at all. We’ve set it to come on for a couple of hours in the night when we’re on economy 7. We had already set the temperature to 45 and the water is coming out of the taps at that temperature.Eco mode was not selected. We’ve selected it.So. For a Heat Pump numpty like me: any other basic recommended actions we can take at th
Heat Pumps and the impact on your Carbon Footprint Are Heat Pumps value for money? Suppose you had £10,000+ to spend on an energy-related installation for your house. How might you apportion the fund across the following three categories?Reducing heat-loss / improving insulation Installing electricity micro-generation such as PV Solar Panels and possibly a Home Storage Battery too Installing a Heat pump, either ground-source (GSHP) or air-source (ASHP)There isn’t one single ‘correct’ answer, and the expenditure will be apportioned differently according to the current state of the property.Over the past 25-years the public has tended to put most of the money into Solar Panels (option 2), with the rest being used in additional loft or wall insulation (1). But this choice has been biased due to the Feed-In Tariff which paid money to households generating electricity, even if most of that was consumed by the home itself instead of being exported to the Grid.The FIT has now gone. The replac
HiBrowsing the forum I found reference to the fuel mix OVO uses https://www.ovoenergy.com/ovo-fuel-mix When you follow this link it says OVO is 100% renewable. Further down it says fuel mix includes 49.6% Natural gas. At least that is how I read it.Elsewhere there is a lot of explanation about how the market operates (electrons don’t know what pushed them down the wire and pricing is for a kW irrespective of source). But ultimately the 100% and 49.6% seem to be contradictory!Can someone explain, please?

I have read the advice on this guide but I still don't know what to do and I hope there are others here who have the same situationWe have a PHEV (Mitsubishi Outlander) with a 12kwh pack which takes roughly 4 hours to charge with the 10amp charger or 2 with the 30amp.We have a PV array with AC output of up to 4.8kwWe're on the Better Smart plan, so pay the same, regardless of time of day.The car needs to be charged twice per day during the week, sometimes more, and once or twice per day on weekends.The car gets charged from 10am to 4pm and between 1am and 5am.We use most of our electricity after 5pm, cooking supper, etc.I can't decide whether to:Stay on this planSwitch to economy 7 (and get nailed in winter and when the weather is rubbish)Switch to OVO Drive (see above regarding PV and it looks like I'd have to shell out for a smart charger… difficult to get more information without applying) If anyone else has this setup, then I'd like to hear what you have discovered
I have a SOLARMAN smart app. During the day when solar panels are producing energy it shows as a blue area on the graph. At roughly the same time it shows a similar size red area of energy usage at a time when almost no energy is being used in the housewe have a solar array, 1 battery, a hot water cylinder and a SOLARiBoost+thank youphilip
Updated on 14/04/22 by Jess_OVO Thanks to the help of our PV champions and Plan Zero heroes, we’ve put together a collaborative guide to all things solar. Thinking about getting into the micro-generation game but don’t know where to start? - Check out the info below for what you might need to consider before joining the solar panel club. Below is a series of experiences and insights from community members for you to get a different point of view on this energy generating tech. Please note that this is not the viewpoint and advice of OVO. As always, it’s important to do your own research. Check out our Forum guidelines here. How many PV panels do you have, and what type? I have PV panels - 14 of them, styled “8.33 285w ETERNITY+10 PV modules”. They are made by Table Trading S.L. aka 8.33 Solar. I have a 4kW domestic solar PV installation since 2016.· The array is 12 x 330w Panasonic HIT N Hybrid Modules. We chose Panasonic as it came with 25 Year Performance
Our house isn’t on the gas grid - we have an LPG tank for heating fuel. But we also have an electric car and a Kaluza-compatible smart charger. Drive anytime appears to be an electricity and gas tariff - are we still able to sign up even though we don’t have mains gas? (currently not an Ovo customer, but looking to switch).
Is Vehicle-to-grid (V2G) or Vehicle-to-home (V2H) plan available from any energy supplier in UK yet?
I have been so frustrated for past 3 years as only "in trial" V2H or V2G systems.I can't find any supplier of V2H or V2G adapter for my spare 2nd nissan leaf car. Does anyone know or have any experience of real life V2H or V2G in UK?
Updated on 14/04/22 by Jess_OVO What do you think about the latest EV legislation news See the Sunday Times article here. @Chris_OVO posted recently on his LinkedIn page about this and we both wanted to share this here: Good intentions, poor execution. If, based on 2021 selling around 200,000 Plug In Vehicles, EVERY person who bought a Plug-in Vehicle also bought a new home, there would still be 43,000 chargers installed, running out of warranty, totally neglected. Ask the question: How many people are buying a new house AND getting a new car, AND in the 15% that are buying an EV? The stats simply do not back up a need to INSTALL these chargers straight away. Even the inevitable increase of Plug-In Vehicle sales isn't going to suddenly lead to these chargers being used - the amount of homes that the UK is aiming to build per year is 340,000 for the next 10 years. The answer isn't to force the install of EV chargers, it's to put the wiring in place, ready for the consumer to select
Having recently enabled weather dependant mode and as the temps have dropped, my target LWT is 55° today.After 2.5 hours of pump operation this morning (outside temp 1°), the LWT has reached 49°. Does everyone else’s system take this sort of time to get up to temp? Just want to check what the norm is before raising a query to Retrofit/Daikin.
I’ve recently had a Daikin ASHP installed under the OVO heat pump trial. It comes with a simple Honeywell room thermostat. Does anyone know if using a smart thermostat, such as Tado, would cause any issues with this system? Also, am I even allowed to change the thermostat under the trial terms, I’m not sure? Any advice on smart thermostats appreciated. Thanks.
How can I calculate the cost of OVO Drive Anytime based on my Electric Vehicle (EV) charging patterns?
I need some help with my maths and I am sure there are some people that love these things:Just put a deposit down on a Mach-E and so need a home charger and decent tariff. I have looked at the OVO Drive and it just looks wrong. Here are my workings based on my January bill.Electricity - £110.08 @ 536.33kwh = 0.205ppkwhGas - £62.91 @ 1989.94kwh = 0.031ppkwhIf I take up OVO Drive i can benefit from 5ppkh through an Indra charger. Sounds great but the gas and electric charges for the rest of the usage goes up:Electric goes to 0.3078ppkwh and gas goes to 0.086ppkwh. Why the gas goes up I have no idea.That means on the Drive tariff and the usage for January I would have paid £162.22 more on my regular bill to benefit from a 5p charging price. Even if I charged my car for 10 hours every night through January (Not likely) it would have cost me £15.50 at the 5p rate and only £62 at my current rate so how can OVO justify a massive hike in the price. Have I got my sums right?It is labelled as a
I'm getting an electric vehicle (EV) charger but how to get my meter tails upgraded and a DP isolation switch fitted? Who and how much?
Hi,I’m in the process of purchasing an EV. Before the charger install I’ve been advised to have the meter tails uprated and an isolator switch fitted before my electrician fits a new consumer unit and installs the charger.I have been charged £264.25 for OVO to carry out the work in the meter cupboard. Thinking this seemed a bit much I did some research and came across this price list by OVO. DP isolator says £158.25 but has no mention of the meter tails. I called my DNO and they said the tails are normally updated during any work carried out by the supplier like a new meter. My smart meter was installed last year and the old tails were left in place. So my question is, why have I been charged £264 for an isolator normally costing £158 and the DNO says meter tails are normally updated during any work carried out as they are not my responsibility and down to the supplier to ensure they are safe and sized according to the demand required.Many thanks.

Well, the date is now 1st January 2022, so that can only mean one thing…On behalf of the entire OVO Forum community, I’d like to wish everyone who reads this a very big Happy New Year! I would do the sparkly text effects, but those got left behind when Microsoft Office Word 2003 stopped being a thing. Oh well. XDNormally, @Tim_OVO or @Jess_OVO would make a post like this, but I’m afraid they fell into my trap this morning and are currently… Erm… Unavailable… Yes, that’s the reason. They might be back later this year if they can escape my lair. Muhahahahaha!2021 has been a pretty strong year on the forum with a huge number of topics created, masses of comments posted and a ton of answers and advice given. But 2022 has some new plans being cooked up right now. I can’t reveal what they are just yet, but I will say this much. Look out for some new forum features coming soon.We’re also on the lookout for the next Plan Zero Hero as well. The way to earn it is a sekrit, but it’s definitely p
Updated on 09/08/22 by Tim_OVO:Our post V2G trial plans and FAQs have now been announced over here. Export credits applied to customers using the Vehicle to Grid charger will be paid at the following rates outlined here The much-awaited announcement on the V2G trial for me was a fizzle as compared to a blast. The opportunity to create, innovate and progress the V2G trial was rather missed. I am fully supportive and appreciative of the OvO trial however the incentives for the participants appear to be under-represented. If this has to succeed as a sustainable business model, it must work for the customers, Kaluza, Indra and OvO. Let’s look at some of the benefits (for the customer) at the end of the trial:a free (Not smart if you exit the contract with OvO) charger with ChaDemo cable Now given this is trial funded by the UK taxpayers, the cost of the V2G unit is being ignored. That is a whole different discussion on the viability of V2G technology. In contrast, most of the trialists wo
What's the best Home Energy Storage option for retaining domestic stored solar power in preparation for power cuts?
Due to inept official planning and misguided political priorities there seems to be a consensus that power cuts are more likely than usual this coming winter. In fact. preparation for power cuts was a strong motivation to me for installing extra storage batteries to keep systems operating during outages.However, I am looking for some help in how best to achieve this.I live in Cheshire in the NW and have 28 JASolar PVMono 345 south-facing panels, nominal output 9.5kW.4 Pylontech 3.5kWh batteries = nominally 14kWh capacity.Pre-solar my domestic load averaged around 10 kWh per 24 hours and is still similar.I don’t fully understand the relationship or the interface between the AC grid and my installation as it was all put in by a professional team.The main inverter is Solis 5G Single Phase.Batteries are controlled by Growatt SPA3000TL BL (AC Coupled inverter)(BTW, does anyone really know what SPA means in this context? There are vague possibilities among the over 200 meanings listed in “th
The electricity grid in balance - guide We are more often hearing energy experts use the phrase “Balancing the grid”. It is an important concept and one with which we should try to be engaged as we accelerate towards a zero-carbon, energy-efficient future. However the term “Grid Balancing” is applied in various ways according to which part of the electricity grid is being referred to. A Government spokesman will use grid balancing in a very different way to a Network Planner working for a Distribution Network Operator (DNO). 1: National Grid Balancing - Supply and DemandThis is the concept of grid balancing which is most often being referred to, and is the simplest to understand. It is also one that has existed since the formation of the National Grid in 1926. To keep the electricity grid in balance, the amount being generated (the Supply) must equal the quantity required for consumption (the Demand).This is the task of National Grid PLC. However, they are only directly in control of t
