Hi,
I recommend adding a Chargehanger to your setup, helps to keep the cable from trailing on the floor.
Would you recommend getting wall charging station at home, even I'm planning to do 60-70kms a day?
@@smartniraj a 10A mobile connector may be enough if you’re only driving that much per day
@@LudicrousFeed Thank you, i wanted to drive the car first and see if 10A enough or not. Have you tried charging at the Tesla charging station? or
@@smartniraj It should charge at the V2 Tesla Supercharger stations (the ones with 2 plugs). There’s a known issue currently with the V3 stalls which BYD are apparently aware of and working toward a fix 🤞
Thanks Tom. Informative as usual. I’ve got a Tesla M3 with gen 3 charger and powerwall. I’m using charge HQ and it’s brilliant. The solar tracking function in charge HQ allows only excess solar to charge my Tesla. It gets all the info it needs via the powerwall. This was an easy setup with all the info you need on the charge HQ website. It doesn’t matter that Charge HQ can’t talk to the gen 3 charger if you have a powerwall. I’ve signed up to the Tesla energy plan so to take advantage of the feed in tariff after 2pm charge HQ will also stop charging my Tesla at this time. There’s endless combinations of timing and scheduling I can do. Charge HQ has made managing my solar and charging a breeze. I wish I knew about this when I first got my M3. Hope this helps someone. It’s you Tom I need to thank as you made me aware of charge HQ over a year ago.
Pleasure! Agreed, ChargeHQ does make things easy and is good value
Great video…thanks Tom
Pleasure
Great video, thanks.
Pleasure
Great vid
Very informative video
🙏👍
Hey Tom you convinced me that I made the right choice of purchasing a Tesla Gen 3 charger. I looked at plenty of non-Tesla chargers & just can’t justify the extra expense for no real world advantage. I tend to just charge at night 00:00-06:00 at 8c/Kw rather than use solar. This leaves the solar generation for my pool pump & thirsty air conditioner & export excess @ 8c/Kw. In winter when solar is next to useless I will charge 11:00-14:00 for free from the grid. I don’t care where my power comes from as I don’t buy into the Man Made Climate Change theory so cheapest is best. The extra cost of batteries & power meters just don’t add up at the moment but I’m glad you have invested to show what can be achieved. Keep up the great reviews
Thanks! Yes the Tesla Gen 3 Wall Connector works well for the purpose you described 👍
Hi I'm Tony , love your chanel. I'm not yet an ev owner but will consider one in the future. I've just bought a brand new i30n sedan. Loving it so far. But am very impressed with bud seal performance model reviews. Love your descriptive information as a daily user for commuting to work and daily family trips. Keep up the great info, hopefully one day soon I'll switch to an ev car.
Glad you're enjoying my content!
Thanks Tom. I saw you on stage at EE on the weekend - good stuff! I’m getting an Ocular IQ from EVSE soon for my Seal. You actually helped me pull the trigger on the seal, so thanks!
I was interested to see that the cars charged from your powerwall. Do you have a way to coordinate them so that that doesn’t happen?
It sounds like you have a bunch of credits with Powershop. When those run out, you should check out what we’re doing at Amber.
Cheers!
Thanks! I’ll definitely shop around after my credits expire 😁
You can set the PW as “time based control” and that keeps it from being drained when the tariffs are cheap (which can also be configured)
My dream setup (battery, solar and home charger). One day I'll get there. Nice one, Tom.
One more thing to add to the Wishlist: V2H ✨
I just use a 15A GPO. Delivers about 3KW. The electrician charged $350 to install.
Our cars use LiFePO, we normally charge them to 100% once per week over night. In those occasional weeks we do a bit more driving, we can give them a bit more, also if we are doing a trip we charge to 100% night before.
Good practice 👍
Sounds like the smart thing to do
I have a complicated charge setup using custom software (I created for my self that will only ever work on my setup) that balances chaging my solar battery and Model Y from solar only. Currently producing 13 KW solar and feeding 7KW to my solar batteries and 3 Kw to my model Y and the remaining 3 kw consumed by my home currently estimated to finish charging between 3 to 3:30. It estimates a 30 min bracket based on house usage and solar generation forecast data.
Looks like a great set-up, I'm in Sydney also and would love to charge my car by solar . I have a time of use meter so my unit's power is off peak from 10 pm to 6am everyday. (Because I'm in a unit I can't get solar panels . ) So I have a timer to turn on my hot water when it's off peak and also I only have single phase power to charge an EV in off peak
Excellent use of your off-peak tariff 👏
Thankyou for a great video I am surprised of how small the unit is, I believe these chargers do not have a CT (current) clamp for solar aware, instead they have a power meter in your case a three phase power meter inside your fuse box, do these usually come in the box with the charger or are they a additional cost? Also do they take much room inside your fuse box? Maybe a follow up video of this device inside your fuse box? Keep up the great work you do 😊😊
Thanks! It’s an additional cost for the power meter
I just use the Tesla charger between 10 and 3 during the day. It just sucks up whatever excess is going on with the solar plus some grid. It doesn't really need to be any more complicated than that does it?
Sure, if it works for you and if you're happy to use grid power. This is for those who want to just use solar only with minimal grid input
@@LudicrousFeed OK. Thanks for the feed back Tom.
I like your videos man. When you picked up your car did they said anything about breaking in the battery? I saw some brazilian videos about the BYD Seal where they say that mechanic`s from BYD recommend all users to do 2000 km without using sport mode so that the batteries can break in? DId they said the same to you?
Thanks in advance
I think it’s also stated in the manual although I still don’t understand why you need to break in the battery: doesn’t make sense
@@LudicrousFeed I bought a BYD Seal Wich will be delivered towards the end of March, that is why I was asking. I asked that here to the people from BYD in Portugal and on the garage where I bought my car they said that I could drive has I wish. But I do Rc Helicopters has an hobby and all the time I buy lipo battery the manufacturer says to go gentle on the 5 firsts flights to break in the battery. I will check the manual when I get the car and ask them again. Thank you for your kind reply.
Just installed the evnex E2. Any tips for enabling the changer after install and set up? Mine remains on an oscillating white light, and enabling the charger via the app shows the green ‘success’ message, yet the white light and charger disable remains in the app. 2:24
Apologies I don't have any experience with this brand of EVSE. Hopefully one of our viewers can help
A couple of questions. Can you schedule the charging time at the car (Seal). So if you are charging from a GPO it activates during off peak.
Secondly, surely it’s better to send excess solar to the Grid as feedin tariffs would be higher than off peak rate?
Yes you can schedule from the Seal
Depends on your plan. My FiT is 5c vs off peak is 10c
@@LudicrousFeed thanks, my FIT is $0.52 as an early adopter, locked in. So off peak is the way to go.
Definitely in your case go off-peak 😁
Hey Tom, great video. When you say that the BYD Seal will be woken up by the EVSE for the scheduled charge, roughly how long was the car plugged in but not charging for prior to the scheduled charge? Was the Seal definitely in sleep mode? I have an Atto 3 and our EVSE cannot wake it once the car has gone to sleep, so was just wondering if this has been rectified for the Seal. Cheers Leon.
I plug in once I get home from work ... let's say 6pm. Then it is woken up at midnight for the charge session. I leave my car unlocked (but powered off) in the garage. It has been this way since I took delivery in late Dec 2023
Evnex chargers have a solution for the Atto 3 falling asleep. They had a blog on it which google would probably find for you.
Fantastic video! I have a query: Is the BYD mobile charger compatible with the Tesla Model 3/Y?
Thanks! Worth a test 👍
Will the wallbox dynamically shift between single and 3 phase like the zappi will?
Unfortunately not … that’s the down side
Fantastic video. I have a seal and considering the wallbox on a single phase supply but taking advantage of a large solar excess. Will the 7.4kw single phase supply charge the seal at that rate minus losses?
Is your solar inverter single or three phase? Given you have a regular large solar excess, I presume you have a three phase inverter ... in which case a single phase installation of the Wallbox will mean that you may only benefit from 1/3 of the excess solar production. I can't find any sources online to confirm this so I'm happy to be corrected. Unfortunately as you can see even with a three phase Wallbox setup you'll still only get 1/3 of the excess production ... this is the disadvantage of vehicles with single phase onboard chargers such as the Seal 😔
@@LudicrousFeed thanks for the prompt reply. 9.8kw of panels on a single phase supply/inverter. House generally draws around 2 to 4kw depending. But I have limited export to the grid to 6kw. Would prefer to push the excess to the car and remainder to the grid. As I don’t have a battery.
Then your setup is easy. Install a single phase solar charger and your excess solar production will go to the car 👍
Hi Tom
Pick up my Seal Premium next week. Can i install a 15amp socket at home to charge Seal faster. I was told the Charger that comes with the car only works on 10Amp socket?
Yes my understanding is that the included mobile charger can only do 10A
I recommend a product similar to this from EVSE: Tesla UMC Universal Mobile Connector Charger versus Alternative EVSE
th-cam.com/video/R7l17dGC_pc/w-d-xo.html
@@LudicrousFeed Many thanks
Given you have 3 phase electricity presumably you can charge both at the same time at quite a good rate?
My electricians: LME Electrical in Sydney kindly setup our system such as we can potentially supply up to 22kW at both wall connectors if this is ever required
@@LudicrousFeed wow. Awesome.
How do you get 22kW 3-phase working through solar/battery? Do you have one battery per phase?
My Powerwall is only single phase. I have a mix of microinverters and a string inverter across the different phases.
@@LudicrousFeed we have 10kW solar on our
Place and I’m considering a 7kW single phase wall charger (BMW unit) - changing over from my bmw 330e to a BYD seal performance.
So much more car for the $ and compared
To the i4 is a step up in many ways. The sound system is a step down from the 330e Harmon Kardon system but maybe aftermarket can fix that…
Hi, we just bought Seal and Tesla 3… what ev charger would best work for both. No solar yet
Both chargers reviewed in this video would suffice. I also recommend looking at the Ocular range from EVSE: BLUETOOTH CONTROLLED ELECTRIC VEHICLE CHARGER | Ocular LTE Plus Review
th-cam.com/video/MOTuw0AixAU/w-d-xo.html
Stay tuned as I will have more Ocular reviews coming up
Great video. Not sure if I missed it. At 7kw max charging for the Seal, how long is it taking you at home to get a full charge?
The AC "full charge" time should be seen as an outdated concept and something most EV owners don't put into practice. Most of us top up a bit either every night or every few nights or couple of times a week depending on our usage. For example I will only charge max 4h each night (0000 to 0400) due to cheaper tariffs from my provider, Powershop. But if you must know, it is a matter of a simple calculation. A 82kWh battery charging at 7kW will take approx 11-12 hours for a "full charge"
Thanks. Should have figured that out myself ;) Likely I will go a Seal on Novated Lease in the coming months. Can you see any benefit of paying more for the 22kw 3phase installation for the Seal or save some costs and get a 7kw install?@@LudicrousFeed
The cost hurdle is the initial installation. It’s not much more money to buy a 3-phase EVSE over a single phase unit
- I would personally go 3-phase 22kW to future proof my home if/when you upgrade to a car that can support that rate.
What distance do you drive each day? I am going to be driving 200km each day. I am trying to decide whether or not I get a home charger or just use the local chargers.
Depending on my work schedule and family commitments I can sometimes drive up to 100km per day. For your sanity, get a home charger. Public charging is a last resort option for me
Hey Tom, how does the Wallbox Pulsar go switching between 1 Phase and 3 Phase when Solar ramps up and down. I bought a Fronius Wattpilot GO 22J and I am extremely disappointed with the way it moves between single and 3 phase.
The Wattpilot GO stops charging on single phase, then switches to 3 phase to start charging at a higher rate. On a cloudy day the unit stops and starts continually.
So with three phase installations, if you leave it on "full green" it requires a minimum of 4.1kW before it will start charging on three phase. On "Eco Mode" it will only need 1.4kW on three phase so I generally leave it on Eco Mode otherwise it will just switch off if it's any lower than 4.1kW on Eco Mode. I explain it around 6:30
@@LudicrousFeed Yeah, I watched the video. What I'm not clear on is how the Pulsar handles moving from single to three phase - e.g. is it seamless (e.g. doesnt stop charging) as it moves from single to three phase, or from three phase to single phase based on available kW from solar.
I'm not sure if it does ... because it always requires 4.1kW minimum?
How far is your wallbox from your inverter?
@@LudicrousFeed Obviously i'm not making myself clear. Apologies.
If I have a Wallbox Pulsar and charging starts in ECO mode at 1.4kW in the morning as the sun rises, and as my solar output increases to 10kW will the Wallbox Pulsar seamlessly, and without interruption increase charging to 10kW via three phase? If a cloud comes out and only 3kW is available will it seamlessly move to single phase. By seamless I mean will it not stop/start the charging.
Hi Tom, when you charge 7kw from the Tesla wall charger into the byd it receives 6.3kw so approximately 0.7kw losses about 10% fron evse to the car.
What are the losses like on the tesla y rwd?
That's what's weird ... no reported losses from EVSE to car in the Y
There's something very strange about the Australian BYD charging setup ... may need to confront EV Direct about this
There is a 10% overhead on charging. Loss is through heat and the charger management system and the car’s battery management system.
If you increase the batteries charge by say 40kwh you will use 44kwh. Same on tesla, polestar and MG
@@BYD_Telsa so every EV has about 10% losses with AC charging. Is the same with the fast DC charging?
% @markng899 Depends on temp and speed of charge but seems to be around 10
@@BYD_Telsa I thought Tom said there was virtually nil losses in the AC charge process for the model Y? Do you have an actual number for reduction in charge rate for the Tesla Tom?
How do the charging losses compare between Tesla and BYD?
What’s interesting is that with Tesla, losses seem to be minimal when AC charging
Is the Wallbox compatible with the Enphase solar system,(envoy system )?
That’s what I’m also using currently … Enphase microinverters 👍
@@LudicrousFeedthanks Tom, we don’t have a powerwall though so I’m not sure whether that’s an essential component for the charge on solar functionality. The Model Y is scheduled for delivery next Saturday and we’ve yet to organise charging at home 😢
Yes you’ll need a PowerWall for the Tesla Charge on Solar function
@@LudicrousFeedthought as much, thanks again. Very helpful videos for first time EV owners like us 😊
I considering a three phase charger atm that does 22kw meaning my car less likely to loose time when i recharge and need my car for Rideshare
You will be limited by your weakest link so despite your EVSE delivering 22kW, you’ll only charge as fast as your car allows you. There are some cars that do charge at 22kW …
@@LudicrousFeed I wonder if this is software limited for ac charging considering some car will chagre at DC speed
@@tehtron It’s probably an inverter issue. Whether it’s software locked or whether you need new hardware probably varies between OEMs
The Wallbox load management is not detecting that the Seal is a single phase car and adjusting its load management accordingly, hence the difference in the unconsumed solar between the Seal and Tesla. It actually has nothing to do with the Seal.
Our charging system, which is also three phase, detects the number of phases where there is a current draw by the EV and adjusts its load management accordingly. :-) Wallbox needs that capability without having to specifically purchase a single phase charger as I'm sure many single phase EVs will be plugged into its three phase charger with load management.
Re. scheduling, we had to comply with the UK smart charging regulations which requires a randomised 10 minute window of when a scheduled charge begins. I can see this becoming a requirement here. The requirement is in place so that many EVSEs don't all start charging at once. It is a reasonable thing for an EVSE to incorporate, particularly if they also need to operate in the UK.
Finally, the loss of current between the EVSE and the Seal is BYD's issue. Nothing to do with the EVSE, its cable or plug.
Unfortunately I’m not sure if the Wallbox can cycle between the different phases to account for the change in supply 😔
- Agreed the randomised 10min window is a sensible requirement
I’ll have to find out more why there is so much loss between the EVSE and the car
I'm pretty sure it is the Seal at fault re current loss@@LudicrousFeed - you should see something similar re. the Tesla charger and Seal.
Re. the EVSE and cycling phases... not quite what I mean. We detect the current draw of the EV and then relay that info back to the load management via the EVSE. The load management then considers the number of phases actually being drawn from before deciding how much more to allocate. If it detects a single phase then it will provide all remaining current avaialble to that single phase. Otherwise it has to divide by the number of phases. I'm pretty sure Wallbox are measuring the current per phase at the EVSE and could do something similar if they wanted.
Hopefully it’s a software thing for Wallbox? Not sure if they have the hardware already inbuilt to support. I’ll have to investigate
@@LudicrousFeed If you are game to open up the wallbox (turn it off at the wall!) then if there are three CTs then they have the hardware in place to do what we do. I'm pretty sure they'll have three CTs, otherwise they'd just be guessing the draw on the other two phases given a single CT. And that would be wrong. :-)
I am not convinced just yet that charging an EV is a good thing in your garage. Certainly, the charge points inside the garage is a good idea for security purposes, but I would be passing the cable out to your driveway and recharging your EVs out there. Not sure how you get on in an apartment situation (case by case I guess). I know this seems extreme and hey, what could possibly go wrong? Right.
The chargers are very smart and full of great options, but it is like having a fuel service station install the bowser at your place, and at your cost. I hope you can lock out the power wall, just in case you need the energy for something else.
Could the loses on the BYD be due to preconditioning of the battery pack?
I can understand your concern but one would hope there are safety mechanisms within the vehicles in place to prevent overheating. I've been charging an EV in this garage since 2016 through all possible weather scenarios in Sydney without any issues thus far. You can set a reserve % for your PowerWall 2
I'm not sure what the issue you believe there is?Cars belong in garage / carports.
I have been charging my EV in my garage for almost 3 years. No issue to report.
@@emmett3067 Good for you. Cars do indeed belong in Garages, and good you are here to report it. 👍
@@GolLeeMe Jerk.
u r on 3 phase 32A setup?
👍
@@LudicrousFeed oh my, does your electric supplier charge u 3X the daily supply charge to a single phase? i read on AGL - single phase charge $1/day whilst 3 phase would be $3/day
@@MrLoichin No that’s not how it works in Australia, daily supply is the same regardless usually. I know which forum you’re referring to - that answer is not officially from AGL so be careful what you read.

Hi Tom
Can the wallbox charge a tesla.
Yes, I demonstrate it doing so for our Model Y in this video
Sorry Tom, I should watch the whole video 😂
Hey mate, can we chat. I'd like to buy 30 mins of your time to chat about the BYD Seal Pref model, best way to open a line of communication? Email perhaps? Im also Australia and needing some questions answered from someone othe than a sales rep. Cheers

The seal is only single phase.
Yes but I was hoping it would get higher than 1.7kW when there was so much more surplus available! One would have thought it would be able to utilise up to at least 4kW+ which is the output I had that day 😭
@@LudicrousFeed presumably the 4kw is spread across the 3 phases, so it can only use 1/3 of it
Yeah you're only getting one phase of that solar. It's the disadvantage of the byd there. You'll also find if you plug the byd into an 11kW charger it'll only charge at 3.6kW for the same reason.
Annoying when byd in Europe charges at 11kW 3 phase.
If you had the single phase charger you'd get the whole solar output up to the 7kW
Well actually I'm getting 7kW at the charger and 6.3kW at the car for both my Wallbox and Tesla Gen 3 when charging manually (without solar charging) and both are three phase installations 22kW respectively - makes sense I suppose: 1/3 of 22kW is approx 7kW
@@LudicrousFeed yep. 7kw is 32a single phase, 11kw is 16a 3 phase, 22kw is 32a 3 phase
