#homebattery #solarpv #givenergy - วิทยาศาสตร์และเทคโนโลยี
I bought a Givenergy system 18 months ago based on your original video and have not been disappointed. For me the most important thing has been the support team. There's an active forum but whenever I've phoned, I've been able to speak to a human with a max wait time of about 5 minutes - that is sheer rocking horse sh*t these days.....
The local integration via Home Assistant is awesome and as you say removes cloud from the equation. So far I just monitor on a dashboard but now I've moved to Octopus Flux I really want to look at putting some intelligence into the charge/discharge timings to maximise savings.
With batteries size really does matter - I have 8kw/h and would honestly like double or even triple - I *hate* throwing power back at the grid.
@@user-ep3iv1pc8k lol whatever....
Thanks again for these type of videos EVM. It's great to get the information from a user rather than a company. Always watch your intuitive videos & appreciate the depth you go into to give us the watcher the insights you have. Cheers.
I agree that having local control capabilities and not through the cloud, is important. Overall I think you have made a good choice for your situation
Thanks for the update video. I'm getting a 9.5kw battery (AC coupled) fitted in a month so it's useful to see the main features of the app. Looking forward to using more solar instead of sending 60-70% per year back to the grid 👍
Great video! Agree with everything you have said. I love my GivEnergy battery and would love another to match your system and it's definitely up there with the best on the market still! I was supposed to get the Gen2 inverter installed as part of my system, but after Covid I could only get the Gen1 when my install was done... So an upgrade like yours may well be my path forward in future, mostly for winter coverage and if I get a heat pump in future! Thanks!
Have GivEnergy 9.5 battery with their AC coupled inverter. This was added about 9 months ago to our 8 year old solar system. Huge difference to bills.
Just gone double electric on the cars too. Had my 24kwH Leaf for about 2 years and just added MG ZS. Both quite short range but ideal for our usage.
Added Zappi charger as I wanted untethered (quiet public access to our parking) and the GivEnergy one seemed to only be tethered.
Love the channel has been huge impact on some of our choices!
Great video as always. We ordered our solar+battery system back in November, but with just one 9.5kW battery. We then had AirCon fitted and I asked you the question on one of your lives earlier this year if you thought is was a good idea to get another battery as our daily consumption, during the Winter, was around 21kWh a day (using the A/C for heating). You said if we could get the batteries charged in the window then yes. Then Octopus launched Flux, happy days. We finally had our system installed earlier this month and so far so good, although the 2nd battery hasn't fully charged yet as once the primary one is at 100% it stops charging the secondary one and the excess solar is going to the grid (for free as we haven't swapped tariffs yet). So thank you for your videos and knowledge, keep up the good work.
I bought the givenergy setup last year based on your review back then. Its been working fine.
Another great review of your Givenergy setup. I went to a Givernergy system after your last excellent review. I had to compromise at the time due to covid so had to change from 2x8KW batteries to 4x5.2KWh batteries giving us 20.8KW. After 18 months it has been nearly 100% perfect with the only snag being the Gen 1 inverter could only charge/discharge the batteries at 2.6Kw, however it hasn't been that big an issue. The awesome part of the hybrid inverter is when I get max sun the inverter hits just over 7KW, 2.6KW of DC + 4.4KW of AC. Once the batteries are full its back to 5.2KW AC which is mostly going into the Zappi and into one of our EVs. Love it, especially the app and web interface. Considering a Gen 3, it will give me a higher charge/discharge rate but need to see if it makes financial sense. Let us know how you get on with it.
Wow, that sounds like an incredible power station! It definitely seems like a reliable and versatile option for outdoor enthusiasts like us. With its massive capacity, powerful output, and fast recharging capabilities, it would definitely be a great addition to anyone's camping gear. Thanks for sharing this recommendation! 👍
I think you've done well with the choice. Ive just had mine installed last week and went with powerwall and enphase microinverters as its less complex to install better scalability (at this point I only installed less than half of the solar I want/need) redundancy and its less components in the house. The downside is that it's more expensive for less ROI than yours. My neighbor has had the same as yours (minus the second battery) installed for a couple of months and is very happy with it. Great value and very nice nice ecosystem :)
Hi EVM, thanks so much for this video. We have an EV and Octopus Go, but no solar or battery at present. We recently started looking at a solar PV and battery installation, mainly because it is impossible to get a decent electricity tariff at the moment, and no sign this is going to change any time soon. The GivEnergy is top on my list too, and your video has helped reinforce this. Another positive it the GivEnergy uses LFP batteries, which makes perfect sense for this application. Love your work!
That givenergy looks amazing.
I've a mix up of everything. Solis hybrid inverter, the myenergi products eddi and zappi, then Weko batteries.
The problem is, I have too many apps. I love my setup it can just be annoying. Love the fact that givenergy even do there own inverter.
I'm glad you're highlighting this with the Libbi, it needs pointing out! I had my eye on it but the high price and the fact I can't install it myself (Myenergi won't sell it to me) has put me off... Givenergy will be my next port of call! Thanks for the video.
Great video. I have A GIV Energy system, which I added to complement the solar panels with solar edge inverter. Zappi charger. I switch on the car charging manually as the I don’t trust the Zappi to manage … it just sucks the battery dry.
I've got Gen 1 Givenergy hybrid with solar and 9.5kWh battery. Very happy with it.
I think the new GivEnergy all in one is gonna wipe the floor with the competitors. 6kw inverter and 13.5kwh usable storage for 6k+vat.
Nice system, at a reasonable price. However if you DIY it, its under HALF the price, i.e.
@@pepermintpilot1694 Yep, I did a 28kWh system with 6kW inverter, two charge controllers and 10kW of solar panels for under 10k Euro. It's not something everyone can do however, so it's good to see prices are becoming more reasonable.
@@upnorthandpersonal Yes, mate. I was not critisising any part of it. Just pointing out there are other way's. Even if you cant DIY, there are others who are willing to help if you are interested enough! Take care!
Still, about 2k too much, if you look at the wholesale prices.
@@pepermintpilot1694I'm thinking about doing this, I see the 9.5kw battery online for £2800+vat, but the people that installed the solar want to charge £5k just for the battery, I got hybrid already, literally just plug and play. Not sure if I'm allowed to install it though without sign of from a sparky...
Brilliant, thanks, we are about to get this ( just 1 x battery, not 2 ) and a whole heap of solar...Your arguments pretty much match ours ! Nice to be validated, cheers ( P.S. Also from Yorkshire, so tight as chuff !! ;-) )
I think ive got the system you've just upgraded from - 8.2 kWh GE battery and gen 1 3.6 inverter. Your old video was one if the reasons i went with the GE system. So far really pleased with it.
Good video, I understand why you went for that system. We have a Tesla 2 battery. Our main reason for choosing it with our solar plus micro inverters was the Tesla comes with a gateway. In the event of a power cut our home is discounted from the grid and powered from the battery. We have had a few short outages of late, wind issues with power lines.
Great system Andy. Likewise we're North Yorkshire with 9.5kwh Giv but gen 1. Limited to charging one battery in 4 hour octo go tariff window. Presume the gen 3 input/output covers fully charging both batteries and peak demand from heat pump. Happy days 👍
I have the 5km hybrid inverter and a 9.5 battery along with a 7.6 array. Very pleased and self sufficient still have gas heating next step is air to air heating. I want the cooling in the summer and we have micro boar pipe through the house
I needed something that would install outside so went for the Powerwall before they were on a very long backlog (now over I think), yes Panasonic make the batteries but in a Tesla factory! It performed superbly last winter with its own heating and cooling circuits that many other batteries do not have and lead to issues with cold during winter. I am fairly sure a Tesla solar integration will be along soon for their wall charger as for them it is only a new bit of software required.
As installers we have decided not to offer the Libbi to our clients for some of the reasons you highlighted. Also love the wider products but that is something that feels over priced and under specified. The Zappi and Eddi are still huge favorites of ours.
The GivEnery AIO and 5kW hybrid is spot on. Battery systems well specified and offer great value. App best on the market imho.
Great video
I bought a Zappi some time ago, very good at handling the car and the solar panels.
Last year I added the Fox EMS battery and inverter. It clips to the solar input, so it also knows what is going on, though it cannot also talk to the Zappi, as far as I am aware. Maybe, if I add the Eddi, it might? I'm currently running at 13KWh but will go to 20 once I move over to a heat pump at some future point.
But either way, it seems to work plenty well enough for now.
I was previously dismissive of GivEnergy because of the comparatively smaller storage, the lack of modularity compared to the rack-mount Fox system, the smaller inverter. Now they seem to have upped their game somewhat, I would happily buy one.
Would have to agree that the GE system works very well. My only downside to having a complete GE system, is that I have a 3 solar string system, but all GE Inverters only support 2 strings, meaning I have a Solis Inverter for the 3 strings fed into GE AC Coupled Inverter.
I had my system installed on 6th April 2023, and its still not fully operational (Solis inverter was installed broken!) - I was hoping that the new GE Inverter would take 3 strings 😞so that the Solis / AC Coupled could be swapped out to a single unit.
Liking the GE plugs, will have to replace my current Tuya versions - cheers
Having had a Givenergy battery and inverter (in the last few days) added to my Solaredge PV system, I'm glad to hear your comments. Although I did my own research, I appreciate your views and knowledge, and I'll admit, you had me second guessing myself for a moment.
Do you think you'll switch to a Givenergy charger as well? Or does the cost outweigh the benefit of having everything in one app?
Did you go with an EPS option?
I'm glad that you also reiterated that a battery/solar setup does not mean you will never draw from the grid. There is always a bit of draw, as the system is balanced and the inverter(s) catch up with things being turned on and off.
Another great video Andy. We've had the GE system for almost a year now and it's been outstanding. Like you, I did a lot of research before purchasing but your original video helped me make the final decision. I'd agree with all of your point made in this video, the GE lead time and product ETA being one of them which you mention at 15:29.
I'm looking to replace our old EV charger 8:47 so have been wating patiently for the release which after being "coming soon" for over a year, seems to be almost here. From the initial test devices, it seems to have had a complete revamp which is good to see. I'd much rather a vendor get a product right rather than rush one out and then the owners have to put up with flawed software for example; VW and CUPRA, I'm looking your way here!
I have a few GE smart plugs 7:50 and I think the are great although the usage graphs seem to not reflect the time you select so that needs some dev work. I've also heard that there's a complete app overhaul due soon so I'm looking forward to what that will bring. (Ahem) SOLAR FORCAST feature please GE.
We’ve had our GivEnergy system since January. Two Gen1 5kW hybrid inverters, a 5.2kW battery and a 9.5kW battery. Overall it works well but its had teething troubles; the twin-inverter setup (needed for the number of solar panels we have) isn’t officially supported by GE. The two inverters act independently of each other - most of the time this just works fine. Initially the two batteries were installed on one inverter which meant the other inverter’s excess power went to the grid and I kept on getting over-voltage errors on sunny days. Moving the batteries so one on each inverter and it works much better.
Would love to get more battery power to run the ASHP through the winter on overnight charge, but the payback period is still too high. 😢
Be aware that battery charge rates are not as good as you think. According to the GE datasheet the Gen3 can charge at 3.3kW (my Gen1 its 2.6kW) so you could struggle to fully charge 19kW of batteries in the overnight off-peak period. Having two inverters does mean I can get twice the throughput.
I'd forgotten how long ago you got your first Givenergy system. Interesting to see you trading up to the new system. I have the tighter footprint of an 1860 terrace and no garage so it's a real head scratcher how to plan a system and locate these large devices. I'm wondering how well Givenergy will get all the bugs out their first gen EV charger at launch, also I thought the LiFePO4 cells came from China even if the design and build of the rest of the system is UK based.
Looking forward to seeing the financial side of this. I'm trying to work out whether to buy a home battery or wait until a)next gen batteries reduce the price of them or b) wait until I can V2G with my car. My man maths looked at a 4 year payback for a home battery but my usage is much lower than yours.
Reassuring.Thank you EVM ... GE all in one is arriving this week
I recall watching Tim and Kat highlighting the doppelgänger that is the KStar and Libbi; I then saw the difference in price when Myenergi launched it and thought that they were taking the proverbial; they clearly think people who have already entered their ecosystem won't look or care about the significant mark up...
The significant markup is enough of an issue that people will ditch the entire ecosystem
I've got the GivEnergy gen 2. It really was in a different league to other options when making the decision about a year ago and it sounds like they are still offering a very competitive proposition. Tesla obviously don't feel the need to attempt to compete on price because they have the name. The app is great - I keep finding more features. The only issue I have is with controlling the discharge, which has been a little odd - sometimes it doesn't discharge.
I'm really happy with my giv energy system. Looking forward to their car charger coming out
Just had our 2nd PowerWall added to our 9kw system. 9 month lead time for the PW's each time. Integrates very well with, though a different Ecosystem to, our Indra Pro charge-point (solar aware).
For us the most important aspect was the size of company behind the tech (never too big to fail, but hopefully not), and the fact the PW is designed to be happy outside, with active cooling/heating of the battery system.
My own advanced man-maths, shows the solar and 1st PW paying for itself in less than 6 years - the 2nd PW will take just over 9yrs. (At a total saving over standard variable rate with no solar & battery of roughly £3k a year)!
We're thinking about it. In 2025 we will be going for solar panels and a battery. I would like to build in capacity allowing me to run a heat pump which will come when the 22 year old gas combi boiler expires. We are a low energy use household and the boiler still has plenty of life in it, unfortunately.
The GivEnergy kit looks like a winner at the moment.
Thnks for the video that confirms that the order i have just placed for the same system with solar panels but only a single battery is the way to go. I am looking at using Octopus Flux for my supplier.
The extra charge for the Libby is the software which supposedly allows priority to the car charging function whether it’s grid only or solar/ battery charging priority… probably a tad more expensive than others solely on this function alone…
It;s a great system. I've got 2 Gen 2 AC inverters and 3 X 9.5 Kwh batteries and since I had them installed in feb it's reduced my bill by £300 month. I've also installed the GIVtcp home assistant integrations which allows huge flexibility in how my batteries are managed. E.g if I've more capacity then I need at the end of day use the batteries to supplement overnight car charging. Otherwise charge the batteries back up to what I need until sun kicks in again . Means No solar is wasted so I can charge the cars and run the entire for free even in night time. Factor in the abilty to vary the charge limit by the solar forecast and do all sorts of clever things in HA and it's a real game changer
£300 pm saving. Wow that's fantastic. Care to elaborate a bit more on your use case. Are powering a swimming pool?😂
@@jonathancullen1337 we are heavy users 2xev, plus working from home and over the last 2 years we’ve used over 13,000 a year . I will admit we probably over specced the batteries for day to day but the GIVtcp and home assistant has meant we found uses for the extra we hadn’t previously thought of
Hi, I'm fairly new to all this. Hoping to install it all in the next house. Accepting the, as yet unknown, costs of upgrading insulation etc, may I ask how much your system cost and what size property you have. (Don't mean to be rude by asking).
Excellent video. Your install looks very neat, can you let us know who your installer was (or did you DIY..?)
In my last I installed solar (with SolarEdge inverter) and Telsa Powerwall and Gateway and had very good service from it. When I moved last year to a new house I researched a range of suppliers but in the end, and despite the long lead times, I specified the same again because for us the ability to keep the critical systems live during a grid outage is critical. Although some systems offered an 'emergency' circuit, none provided complete grid isolation and running, including keeping the solar active. I am just planning to install an air source heat pump so interested to see the follow-up video with the numbers.
Giv now have a gateway equivalent on their All In One system.
@@ElectricVehicleMan Good to know but sadly not available when I was researching this last May,
Thank you for an informative video. Can you part charge it overnight rather than fully charge it?
Excellent video, and excellent choice, me I've gone DIY 4kw solar system £3.5 to installing including mountings, cut switches and Surge protection. 2 x 5kw Growatt SPF 5000 ES Inverters with wiring looms and cut off switches £2.5k. 3 x Seplos Inverters capable of 200A supply design to provide 100A, with cut off switches and fuses cables £7.500. New 18th edition Consumer units x 3 with Surge Protection and wiring £500. Total cost £14K and this was done peice meal over 5 years and its been a fun DIY project. This uses the Solar Assistant App, which can work with Home Assistant. Not into automation I'm old school don't like the idea of someone hacker it and changing all the settings on everything in the house just for fun!! lol
Totally agree about the libbi being over priced. My experience with the Zappi hasn’t been brilliant either, it’s proving a bit unreliable but will hopefully get sorted soon. Can’t argue with the choice of Givenergy, really good products. I went for the Tesla powerwall mainly cause we are fairly rural and get regular power cuts so the backup function swung it and it’s proved really useful. If it wasn’t for that I’m pretty sure we would’ve gone Givenergy too. Spot on that what’s right for one might not be for another.
Honestly MyEnergi need to really up their game because at this rate, I can't see why you'd buy their products unless you're replacing what you already have
Nice - completely agree with everything in the video ☀️⚡️👍🏻
I haven’t gone for a larger battery to cover Winter as the cost isn’t worth it for ~3 months of the year.
With a heat pump it is. And in Yorkshire it last a bit longer than that.
Great video mate
Re. Winter Fish tank power usage : if you leave it in the dark all night you might as well put some insulation around it like I do .
Solaredge 10kW battery is now DC coupled ( more efficient ) No grid permission required. The monitoring and online portal is 2nd to none. Home backup as standard. Car charger, hot water device, optimises and home smart devices all controlled through the app in one eco system. I haven’t been able to find another system better than that. And they will contribute towards scaffolding if they ever have to visit due to fault.
I had a few issues with my two Givenergy 5.2 gen 1 batteries after the software upgrade a couple of months back, I thought they had fixed it remotely but I had a call a couple of weeks back asking if they could come and check the system out anyway. Their engineer pitched up when they said he would, spent nearly two hours testing and stripping things down to check everything and gave it a clean bill of health but they are remote monitoring it anyway. By contrast, I had a Zappi installed at the start of the year, I bought the extended warranty and a few days later it kept sending false tamper alarms. To be fair Myenergy sent a new unit but I’m still fighting to get my extended warranty transferred to the replacement unit. Guess who I’m more likely to buy from in the future?
I think this may work for us. We stepped back from solar as our roof isn't ideal (not that an installer will tell you that) and have instead invested in a Ripple Energy scheme to 'outsource' our renewable energy supply, so the next step is a battery. This seems top be a good way to reduce carbon and not too pricy when combined with an Octopus Energy tariff to match.
N how much tax u paying on your power?
We've put in a Battery only system and use it with Octopus Go.
It's brought our bill down to £75/month for a 5bed house with an EV.
Unfortunately we don’t have those in the states. But enPhase does have that same eco system. I already have their solar. Just need to find money for batteries. Love the update!
I'm trying to get mine taken out, hybrid Inverter with 4x2.6kWh batteries (8kWh available for use only the 9.5kWh has 100% depth of discharge, all other batteries are 80%), it's never worked right, batteries have never balanced, catastrophically failed 3 times in 5 months, support just says problems we are having don't exist or are always somebody else's fault or a firmware issue. We have also had a leak from a battery for a month and Givenergy can't send an engineer to site for 5 to 6 weeks, I hope whatever has leaked isn't toxic. When the servers went down at givenergy our batteries didn't charge overnight
I don't know if we have a Friday afternooner but the shocking support we have received from Givenergy has given us no confidence in the product or the company.
It's a shame as on paper they should be a no brainer and a market leader with the features, no good if it doesn't work though.
Brilliant thanks - If only I understood it 😊
Hi, I’m new to a lot of this. Can you help me with why you have a heat pump as well as an immersion heater? Do you have to have both or could you manage with either one?
I got a 2x9.5 Givenergy battery's + 9KW Solar mainly because of cost and your glowing reviews for your original system. So Glad I did. I use the well documented api to control and Octopus Flux tariff. My last bill was 18th May 2023 - 17th June 2023 + £276.82. I've earned ~£600 these last 3 months :). I have a Sunamp heat battery for hot water. Still contemplating what to do for heating. I don't think Flux will be good for the darker months.
Hi can you please advise who did you battery install it a great video and a very neat and tidy job from what I can see
Les
I have a 3 phase supply which was installed to run my Ground Source Heat Pump, really struggled to find a cost effective 3 phase home battery system that i had confidence in and provided the integration with solar divert EV charging etc covered in the video. In my current arrangement only my heat pump is 3 phase all other house loads are on one phase and we have a high electricity demand. So I came to the same conclusion and purchased the same GivEnergy 5kW Gen 3 Hybrid Inverter, 7kWp ground mounted array with 2 x 9.5kwh batteries on the phase the house uses. I've actually purchased the 3rd battery at the 0% VAT rate whilst buying the solar and will probably connect it even though i won't be able to charge it in my cheap rate window in the winter due to limitations on charging rate on the inverter but i can charge it from solar in the summer months for now. Eventually I'm planning to split the house loads across the 3 phases and buy 2 more inverters, reconfigure the batteries to get 9.5kW of battery on each phase which will optimum for my situation and allow me to have just below 30kWh of battery storage and remove the charging rate issue with the current system.
I think Giv do a 3 phase system.
@@ElectricVehicleManthey do. Not sure if it’s available yet?! I’ve got 3 phase supply coming in next week because of the heat pump coming. They aren’t charging me for the upgrade!
I am seriously considering the Giv Energy all in one and PV installation. I am currently the owner of a Model 3 so want to try and produce my own energy, i have recently retired so suddenly spending more time at home..and carrying out the chores! I am therefore looking at changing my tariff which is currently fixed at a fairly good rate for a few months over to Octopus and integrating everything. I think i have made an error installing a PodPoint EV charger when i bought my M3 last year as it doesn’t seem compatible with solar panels. Thanks very much for the ongoing product information and support. I presume you are charging your M3 off the granny charger at the moment?
We use the growatt 6kwh hybrid inverter & two 6kwh Batt’s charged by 19 panels. Idea is to go hybrid heating with smaller h/pump and keep gas new boiler for extreme temps or electrical faults.
Why would you need a gas boiler for extreme temps or electrical faults?
I don’t get it?
@@ElectricVehicleMan Me neither. You can either back up with infra red or a convection heater or to play really safe go with heat pumps rated to work to -25C. And/or improve airtightness/insulation further. If more redundancy is desired then I guess a non-electric wood gasification or burner dependant on urban vs rural location but still seems superfluous if the house is passive (or near) and electrified.
Hi many thanks for sharing. I was trying to get the same (already have SPV and heat pump) but my DNO declined saying that I was limited to 6kwh and they count the battery in that. Did you have problems like that?
One of the things we need to worry about from any vendor is "will they stay in business and support my phone in future?" App is good- but not having to depend on the app as the sole source of interaction is risky. givEnergy does have a Home Assistant plugin-it'd be worth setting that up on a raspberry pi to see how well it integrates. I like using it to get a single view of the charger (Easee) car (Tronity) and whether I've left the car windows open BMW. Have a play-if you haven't already
It might be a bit of a faff, but I suppose you could run a pipe from the heat pump radiator system and rig it up to heat the aquarium in winter.
#cosyecofish
I already had a Tesla battery so have bought another but as my memory of the price paid fades I’m becoming aware of the significant advantage having enough power to charge the car as the system can deliver a sustained 10 kW. This leaves a margin to power the house and the car at the same time. I have a Zappi and have moved to intelligent Octopus as well.
Previously I found that too often the car was away from home when the export of surplus occurred. Now I can charge the car in the morning the go off leaving the battery to store the solar. The 10 kW also very much reduces the expensive power that took my average price paid over the 7.5p. Winter will be different as I will need to charge the car from the grid a bit but for the moment it is easy to run all ‘entirely’ from solar.
Timely video. Currently have an EV, solar panels, Zappi, Eddi and a heat pump. Have invested in Ripple (Kirk Hill) so last part is a battery. Agree Libbi is expensive. Would be interested in your "man maths" on sizing your battery . I suspect need 10 kWh minimum but with Ripple etc can a 20kWh system be justified ?
Love a nice bit of battery pron 😜
We went solaredge for everything (except panels). Pretty happy with it overall. I suspect we paid a North Wales Premium for the system, but seemed comparable to the price of other solutions available here.
Seems to work well. The battery was new to the market last year though, and functionality has been basic. They're now starting to roll out time of use control, so we will take a look at more advanced octopus tariffs.
I too went with the Solaredge system here in Essex. I am very pleased with it apart from not being able to change the battery profiles which have to be done by the installer. I see they have updated the app to have a little more control of the battery but it still does not meet my needs. Solaredge should provide the end user with full control over the battery like GivEnergy
@@paulcolu talk to your installer, they can set you up with an account manager admin permission to access and alter your system settings. There is no law or other reason why the only the installer should be able to do this. In fact, SolarEdge have been promising for well over a year to make this facility open to the customier. A bit like Mr Musk though, their 'imminent' promise has yet to come to fruition!
Getting my system installed July 17th.
2.4kw solar
3.6 givenergy inverter
9 5kw battery
£10k
Great video, how much was that system, including installation?
I painted my wall white.🖌 Do you know when they are releasing the charger? I have an openEVSE housed in the guts of a rolec wallpod at the moment so I can charge the car from solar. Its a bit DIY with a EM115 talking to a simens PLC over modbus RS485 to get the outgoing ammount, the PLC then talks to a emoncms runnning on a PI via nodered, that then talks to the OpenEVSE to send the data. It's actually really relaible, even though the data is doing about 4 jumps between source and use 🤣
I like your videos but as a 26kWh Powerwall owner on 3-phase, one of the best things about it since about 18 months ago is the way it’s AI “decides” how much to grid charge form our Io cheap rate period based on consumption history and next day Solar forecast. I’m not sure any other systems do this yet despite various supplier promises. And this is without faffing about with home grown / HA automations. I think PW2s now on almost immediate availability too.
Do you get power-outage back-up with that system, Andy? If so, is it the whole house or just a single plug like some seem to offer?
Great set up. How much of a hassle it is to go above 3.6 for the inverter in terms of getting the approval from DNO? Does it need the G99 application?
3kw AC coupled givenergy inverter & 9.5kwh battery. I wanted a solar divert system for ev charging so have a zappi too. If giveenrgy had their ev charger out at the beginning of the year then I would have gone with that.
Very interesting, had this been available five years ago I might have considered this instead of Tesla. Have had one problem with one of my two powerwalls contacted Tesla and it was replaced no questions asked. Took a little while as it was during Covid. I use negligible amounts from the grid in summer and all from four hours of Octopus Go in the winter. Have a Zappi and this works well to divert excess solar to the car or hot water. Have considered a Heat Pump but have a major issue with location and to install would involve major expense over and above the Heat Pump. May consider it if I win the lottery!! My electric bill for a year at 9.5 pence a Kwh is £465 the real killer is the meter charge at £219! We won't talk about gas, but at least the price has come down so annually it will be £830 plus meter charge of £98.50.
🤔10:47 would be great if you could do interview with their R&D engineers showing inside the pack and cells. whether they re-used any (Leaf) cells or did something custom...🤔
factory tour! just like we like to watch Bjorn about Kempower...
also you should have referral code for yourself! 💡
Hi EVM
Could not find your system spec's
I will look at your system as I can see that it is all I need
Thanks
James
I would like a holistic home energy system. I live in an apartment, so I don't have the space and options EVM has. That makes this advice difficult to assess what is right for others. We also have rules we can not just install EV panels and systems, because of influencing the building design and safety concerns with regard to fire hazards with incorrect installment. In apartments we usually try to get into agreement with a single system for the while building with rooftop solar and decide how the energy is used to benefit all (like lighting the building, parking, and waterpump, and excess goed to the grid.
I think for me the most practical system is a solar two panel or single panel 400 Watt option with one or more portable power grids, like an eco flo. Pricey, but makes a lot more sense for an individual appartment owner, simply because space is at a premium.
What was your old inverter? We have a 5 KW gen 2 Givenergy with 9.5kwh battery, and I'm wondering if we'd need to upgrade if we got a heat pump. Cheers!
When you park in that tiny garage how to you exit your car through the sunroof?
Or do you just push it in and out?
Do you have to fold your mirrors in to fit through the door?
Does the Givenergy solution protect you from power cuts, and allow you run the house off the battery during the grid outage, like the Tesla PowerWall and gateway do?
Thankyou
Does it integrate well with your Ohme Home Pro charger? Do you have control over this from a solar diversion point of view?
Great video! Don’t new Tesla Powerwalls contain LFP cells made by CATL, not Panasonic?
Nice roundup. I too like myenergi a lot but agree the Libby is just too expensive. At present they have the unique selling point of the "holy trinity" of battery, car charger and solar diverter but this won't last long. More and more manufacturers will have that soon, as givenergy are demonstrating, and with that pricing I fear they will be left high and dry.
Givenergy are looking really good right now.
I do feel the need to point out that you haven't mentioned Victron as a comparable and indeed more capable system. They have an EV charger now and the software is outstanding. The flexibility and capabilities are amazing. It is very modular and can be installed in many different ways up to and including fully off grid. They are really the only manufacturer that will allow meaningful integration with third party products. You can use their batteries or third party ones to keep the cost down. No modulating solar diverter yet, and I don't know if it is coming, but it is fairly straightforward to make it on/off switch an immersion heater with the inbuilt relays. Only possible downside is that the flexibility brings complexity. Not many people really properly understand it.
What system would you recommend for someone living in the USA?
I've got the same system but using the ac3 inverter as my panes are in a different building, I'm presently addin another inverter so I can get 6 kw drawdown. I. sing the zappi charger with it,at the moment interested to see the givenery charger when it comes out
Perfect setup I've a Solax X1-Fit and 3, 5kw batteries but a hybrid inverter and 2, 9kw batteries would certainly be better over the winter period, Summer I think most battery systems will suffice 👌
Solax could be a massive GivEnergy competitor because they're much cheaper, and they "work with Octopus" but crucially they don't automagically download the best times into your battery. That's where GivEnergy excels
That's one reason why people buy GivEnergy over Solax. Equally they need to release a proper charger that also works similar to both the Ohme and the Zappi.
I reckon a significant chunk of people would then move to Solax. This being said, companies like Solax, Solaris and Growatt are global companies where the UK isn't that big a market so they're in no rush to change things just to change things for the UK market.
One other big reason why GivEnergy is perhaps favoured in the UK at the very least, is due to their UK based customer support. They've also obviously got their AIO system which only MyEnergi have as completion
GivEnergy also have the GivGateway which is weirdly more suited to non UK markets because it automatically switches over to batteries in the event of a power cut.
Looks like a nice investment. You must have spent £10 to £11,000 including install costs. Another approach might be to buy smaller batteries that can be expanded. I have two 2.4 kwh batteries that I can add others to when I can afford to so I am not borrowing money to buy batteries. Working out your house load is quite easy using existing bills over the past 2 years to size your system. . With a 4.8kw arrray and 4.8kwh battery system I can run a 4 bed house with a home office but still have gas. One disadvantage of larger batteries is that they weight a lot so you are limited to where you can put them. All my solar system is in the loft. You also have to consider the inverter as it can only deliver 5kw which is about 20 Amps AC. If you have an electric oven and hob you might exceed the 5kw when you first put them on so you will be reliant on the grid.
Lots of good info, thanks for making the video.
Can I ask - does the system connect to your home wifi, or does it use 4g/5g to send info back to the servers? We don't have any mobile signal in my village and rely on wifi calling on our mobiles, which obviously gives us problems with smartmeters too.
It’s wifi based. (Or I think the more recent inverters can also use an Ethernet connection - but check that).
erm, Tesla absolutely make their own batteries,
!
They literally designed, and engineered, the 2170 battery cell with Panasonic. Tesla literally have 5 Gigafactories making batteries (as well as other EV components), and they also get guess who? ... Panasonic to make the rest of the volume needed to Tesla's spec, be they 2170, or the newer tesla-designed 4680 cell.
Tesla make their own home battery packs, and even commercial "megapacks", their own software too, from charging software/firmware, to consumer "Tesla App", to the "autobidder" software for virtual power plants, etc, they make their own home inverters, etc all vertically integrated.
Im currently in the design stage and stuck with either going for the 9.5kw batt or pay a little more and get the aio, any advice to which to go for would be brillaint
I had to look twice there! With the reflection of the GivEnergy LEDs onto the unit on the left, for a moment there I thought EV Man had gone and bought himself a new-look 100kWh GivEnergy super battery??!! 🤣
I thought the same too! 😂
Need to find an installer for a Giv battery and 6 panels in West Yorkshire. Everyone contacted so far is pushing small 3.2Kwh batteries.
I just paid deposit for Givenergy system including 13.5kw all in one battery with gateway, 18x430w solar panels, 5kw gen3 inverter and EV charger also from Givenergy .
But after watching your video I'm wondering if I made good choice with 13.5kw battery insted of 9.5kw . I think for the parice I could have maybe two of these?
I bought the newest technology from givenergy and whole system is from them as I wanted all be in one place, in one application.
What do you think about my battery choice ?? chould I consider change? I dont think I have made the worst decision ever just want be sure it was the right one.
We have 3-5 power cuts during the year so I thought it make sense to get this battery .
Thanks in advance
Forgot to mention Im also now in the process of quoting me to install heat pump aswell.
I've got a 24kWh Fox cube battery, just hoping it's going to be enough for the heat pump come winter, some peoples HP's are using up to 30kWh on very cold days.
May be a basic question but I presume like your phone analogy, if I have a zappi charger and a givenergy battery then these cannot talk to each other, so you have to choose an eco system and then hope they don’t got bust?
What you didn't say was that you're heat pump was using cheap electricity for 6 hrs at the coldest time at night, so was that taken into consideration to the size of the batteries.
What company did you use to get it installed. I was looking at first for solar but they have closed I think.
Hi
I have a ZAPPI charger for my two Electric cars 🚗
I am with Octopus 🐙
So I looked at the Libbi
Your video and your setup is most interesting
I will have the cash for Solar and an ECO system next year
I am looking for the best Solat panels and the ECO SYSTEM .
Yay this GIVENERY system will not be available for 5 months. No problem.
I shall look into this system from now
Thanks for thisvdeo and all your other video
