- This is my second video on using V2L to power my home. When I made the first video my electric car didn’t have a V2L, but now I have BYD Seal with V2L I wanted to make a second video showing it in action. I suggest you watch the first video to help put this one into context
• Can Vehicle 2 Load pow...
In my inverter I have set the priority: Solar First, then Utility (normally switched off) then Battery. SUB. I have also set the batteries to only charge from solar. If U (V2L) can meet 100% of the house load (my night time usage is 500-800W) then it is as you see in my video. If U can’t support the house load, then B will make up the difference.
I now made a 3rd video which is a simplified summary of what I’m doing.

This is great news! I didn't know that V2L was already possible with the BYD Seal.
This is freaking amazing! you sir are a pioneer!
Fantastic information, I am surprised that not more people review BYD car mentions this feature.👍
It works best with home solar, otherwise you would have to run an extension cable into the house and plug things into it.
In the not too distant future EV's with V2L capability will have a major bearing on the kWh's required for off grid ESS specifications. This video shows exactly how this will happen. 👏👏👏
Thanks Greg
This is amazing info! Its giving me ideas. I have solar as well, but I use about 20 kwh at night in winter mainly for heating. I reckon i can save 100 bucks a month during the winter months using V2L. Just wonder how much it would cost to install the system to work with my exisiting solar system.
Installing a transfer switch shouldn’t cost much, by installer did it when we installed the inverters. I did the rest of the installation myself
Great video, and very well explained! 👏👏👏👏
I have a Model 3 and live in Switzerland. I will be considering the BYD seal once it comes to Switzerland as the Model 3 highland is just a facelift with no USS, front camera and worse functionality by moving all controls to the steering wheel.
Your channel is great sir 🙏🏻
Lol.. I just bought a Seal a week ago as well... With the same idea to power my home at night.
The developers of my gated community in hua hin for whatever reason don't want me to share my solar power with my neighbours any more (over the private village grid they claim to own). So I started to look at a battery solution (as backup for the case the legal solution won't work out). Just need to figure a way to do so without having to replace my on-grid inverter.
Are you on the AseanNow dot com forums? My handle is Bandersnatch and I started the EVs in Thailand discussion.
Brilliant video and thanks for sharing. This is what EVs should be doing along side being used for transportation. Question for you. Can you use V2L to power your house if you have solar however no battery?
Thanks for your kind words. If you have a solar inverter you are good to go. Watch my other video linked in the description
Very interesting. Here in the UK I asked the makers of 'Zappi' chargers, about using the Seal V2L much like a power wall, as they make inverters for their own brand of home battery. I was going to charge the car at cheap 'off-peak' electricity rates. They told me using the car to power the house was not feasible ?
You should watch my first video on V2L linked in the description. I had a transfer switch with 2 AC in (grid and V2L) and one AC out into the inverter
In the UK there may be issues with PE.. If you have a solar inverter with some batteries you could circumvent this by switching off Grid completely and using the car to bump your batteries + house.
Then as soon as the car stops providing power you could swap to grid again (some ATS could help)
Your MG can also do V2L I believe right?
Can you tell us more about your solar setup? How many panels, how many Wp each and what batteries and capacity do you have? Looks really cool
Nevermind, saw all that in your linked video.. crazy impressive.. Don't tell me you also own the rice fields around your house too XD
@@Airbag888 My MG is over 4 years old and doesn’t have V2L but new MGs like the MG4 do.
I started my solar journey 6 years ago with 11kW of 350W PV then increased to 20kW using 550W panels. There a plenty of videos on my channel about my solar system this is the latest: th-cam.com/video/HaQJCp505Ic/w-d-xo.htmlsi=9KTb-aUR_8E-qya4
Land: we have 3.5 Rai (1.4 Acres) (0.56 hectares) around the house and about 7 rai a few hundred meters away - videos on the channel
@@EcoHouseThailand so are you looking to adopt by any chance 😂
@@Airbag888I have a one year old son and no plans to adopt
A glimpse of the future :)
Thanks very much Christian
Most of the new Chinese EV have V2L features now. The feature was originally designed for camping.
The Seal is open for orders in Australia and I am interested in the long range model. I currently have the Atto 3. There are not many good reviews on the operation and performance etc of this EV. You could be one of the first. I am interested in the real world range of the seal. Have you done a video about this topic. You said you have the 82.5kWh battery, is it the RWD or AWD.
Been asked many times for a range update so we are charging to 100% today and will set a trip
Hey! Amazing stuff. What do you think the max discharge could be from the BYD. Are there different charging cables that could make it discharge more. Ambibox have been able to discharge at 7kw it looks like
The V2L adapter that came with the car was restricted to 2.6kW from memory. I bought an aftermarket 3.5kW which I thought was maximum for the car. I only V2L at night as I have a lot of solar and home batteries, so I rarely draw more than 1kW
@@EcoHouseThailand Great, what made you think the 3.5kw was the maximum?
@@georgehartshorn8932 What I have seen online, but I haven’t tested it to confirm
Hey gents did you guys get any more detail or confirmation over the V2L behaviour in this “grid connect” config? Ie does the car LIMIT to 2.6kw ? Or does your aftermarket 3.5kw cable (can you link to this so we can buy it?) increase the discharge rate to 3.5kw?
And or does the seal SHUT DOWN the supply of the v2L if the demand load exceeds the 2.6kw limit ?
This is nice . May I know how much you spent on this system ?
Connecting my EV to my solar system cost about ฿1,000
Thanks for sharing this video. Could you get the car to charge your batteries through the house inverter back to DC?
I have never tried that as it could exceed the V2L maximum power output of 3.5 kW and V2L could well shut down.
@@EcoHouseThailand I just wondered if there was a way of limiting the total draw without disrupting the house load - so just dumping the excess up to say 90% of the total v2l limit.
@@007silverwings I don’t think you can limit power output from the car
@@EcoHouseThailand I guess the only way would be to feed the car into the hybrid inverter and charge the batteries with a programmed wattage limit, or as you do, power the house.
@@007silverwings sounds right
Can you make a video about the lane keeping assist is and if its usable
I have a whole bunch of requests to get through first. The Seal is a fantastic car, its ADAS system is not. I have most of it switched off. Have you watched my video on the infotainment system walkthrough? I talk about it there.
Hi! Just got the Seal here (ireland) and I have noticed and a few others that the zappi charger and a few others show output of 7kw but the byd is only showing 6.2 on the screen. Also tried this at 11kw charger and similar results. Have you noticed any large drops from the supply to the charger? I know there tends to be some transmission loss but this seems excessive.
My home charger pulls 7kW AC but only 6.2 DC is added the battery
Perfect thanks. Sounds like it's losses via the ac dc conversion then.
Excellent video. Thanks! 👍
I dont have engineering experience,how hard is it to learn to use solar panels and storing it in battery then transfer it into power outage to power up a house for noobs like me?
This is a good forum to join www.diysolarforum.com and the TH-cam channel that goes with it www.youtube.com/@WillProwse
Question about Seal's V2L in general (not for powering a house) - does the car need be switched off to use the V2L or can it be on at the same time? I.e. can I run the heater / AC in the car simultaneously when powering some external devices through the charge port?
I have tested V2L with the car on and it still works
Have you checked in how much your Seal draws when V2L is active? I do have reports here and there from different vehicle types that it can be 300 Watts, and I was wondering if the BYD might be any better. 300 extra Watts is a lot if you have one heat pump running which draws less than 200 Watts total.
@fnordpol I can run my house at night for 12 hours with aircon and servers running and only deplete the battery by 7kWh so it seems very efficient
@@EcoHouseThailand I cant tell because I have no idea how much of those 7KWh is getting used by your house and how much is getting used by your car.
If your car burns through en extra 300 Watt just to keep the MCU and Battery condition running, this would loose half of the power you are draining. And the thing is: I have checked the reports and calculated this drain this on other models.
In your scenario it is mostly the question if you should probably charge your house battery from your car, and turn the car of to get better efficiency.
In my case I plan to power a camper with it off grid and it is the question if I can run 2 days or a full week on the battery.
@@fnordpolYou should watch my video on “how to size battery storage for home solar” The seal is way more efficient than my home solar setup. When people choose inverters they never consider their efficiency, but with EVs that’s practically all they talk about.
So, did you AC Couple the Seal V2L to the Generator Port on the inverter? Can you talk about how you made this connection? Thanks
Did you watch the first video on V2L? link in the description
Hi, Peter from Slovakia here. I have Ioniq 5 and intend to power my house with v2l too. However, the output from the car is one phase only. Does your inverter accept this? Plus, if you wish to top up your home battery from your Seal, you must certainly reduce the charging power to keep the house running. The home battery cannot be charged and discharged at the same time. Is it so? Thanks for your reply
Yes my inverter is single phase. I have set my inverter to only charge my home batteries from Solar. I’m not sure if you seen all three videos I have done on V2L, but I talk about running the house load only and only at night. This preserves my home batteries.
Ok, thanks for your reply. My inverter is 3 phase, so I am curious to see how it will treat one-phase power from my car.
Anyway, there is a bidirectional ac charger coming from Renault in the autumn and that should work on cars having v2l capability. And its price should be acceptable too. Unlike these 10.000 usd dc bidirectional chargers coming from us this year
Hi mate your house has a great setup, are you a sparky by trade ?
Thanks. No I’m not but I have research every aspect of the house build for years before we started to build. Everything was planned ahead to be off-grid. The house is super insulated but also with built-in natural cooling. It might look a bit funny, but it is designed on scientific principles for the climate here in Thailand, with rainwater harvesting and fruit and veggies growing in the garden.
@@EcoHouseThailand That is amazing mate that you have a eco friendly house in Thailand, i know all about the seasons here in Thailand as i live and work in BKK.
I have BYD ATTO 3 and SPF5000ES Off Grid, I have tried many different ways but either inverter or Car trips and will not accept any current from the car. I am not sure how its working for you. Any help will be appreciated.
I have the same inverter. Not sure if you have seen all 3 of my videos on this topic this is video 3 of 3 - links in the description. I don’t have a grid connection so V2L is connected to grid input on the inverter. The adapter supplied with my Seal was only rated for 2.5kW, so I bought a higher rated after market one. The cable I used was a high capacity one. I only use V2L at night when I am using less than 1kW most of the time. If you exceed the 2.5kW of the adapter, maybe a pump coming on, the maybe V2L will disconnect and you will have to reset it.
@@EcoHouseThailand I did watch the video, just couldn't understand why it wouldn't work for me, I even reduced AC IN limit to 10A. I even removed AC out to see if batteries would charge, inverters just doesn't accept the car. There are victron forms with people having the same issue. I'm glad your setup works well. Thanks for creating the videos.
Wonder why there’s is a distinction between V2L and V2G when it seems like V2L can be both
Did you watch my first video on V2L linked in the description, it is explained there
What's the output from Seal V2L into watt? Can you run big electric appliance such as aircon, washing machine or microwave?
3.6kW, but the supplied adapter is rated for only 2.6kW, so I bought an after market one. I only use mine at night as I have solar. It can run 2 aircons (8,500 BTU) multiple fans as well as stuff that is switched on 24/7 like fridges, freezers, and servers.
@@EcoHouseThailand What was the aftermarket charger that you bought? Cheers George
@@georgehartshorn8932 Here in Thailand EVs only started selling in 2019 so new EVs come with free wall chargers bundled with the car. My MG came with an MG branded charger and my BYD came with a ABB charger.
@@EcoHouseThailandAs I understand you rather power a few selected appliances than 'home'.
And you still have to disconnect form the wall charger and plug the V2L adapter to do that? Am I right?
The perfect V2H would use the wall charger both ways and allow at last 11 kW load on car!
@pawefiett2468 I power the whole house load at night. My inverter priority setting is Solar, Grid, Batteries, with Grid being my Seal as I don't have a meter. I charge my car from solar during the day as I don't have a grid connection, so yes my charger is unplugged at night. The Seal has V2L using an adapter not V2H using a bi-directional charger like the F150 Lightning which is very expensive.
Sacrifice the car battery to supplement house solar battery. Bummer if the wife wants to go shopping and charge is too low. lol. How many kW is the car battery? (myself wondered about adding a few panels to my system, in order to better support the rainy days but it may still not be enough)
A Tesla PowerWall has 13.5 kWh the BYD Seal has 82.5 kWh. Powering my house load for a few hours is insignificant compared to propelling 2 Tonnes of metal 650km
@@EcoHouseThailand Hmm, my consumption avg is only 40 kWh/day, so, yea, that can help thru the rainy season as long as I can get some sunny days. Is the warranty on the car battery based on time or cycles? How long does it take to transfer say 10 kWh ?
@@darwinjinaWarranty here in Thailand is 8 years 160,000km. The V2L max transfer rate is 3.5kW but it matches the load demand in real time. If your house was using say 1kW/hour then 10kW would take 10 hours.
@@EcoHouseThailand thanks
@@darwinjinaJust wondering what is your family size and your house footage that use 40kW/h a day.
