What EV Charger Do You Have at Home?

Preamble
For the claims that EV is straight forward and more convenient than an ICE (including hybrid), I do not share the same view. Of course, EVs have their merits.
This is based on an experience of owning an Atto 3 as a spare car and having had a rental for a good few days. The list goes from 1. Waiting for a charger, 2. Need to BYO cable, 3. Need to have some sort of charging ability at place of residence, 4. One app for each charging vendor – seriously, I thought credit card have eliminated this non-sense, and 5. The array of non standardised charging options at home.
The FBT exemption makes BEV an attractive option, and the arsenal of BEVs at home is steadily increasing owing to the courtesy of Australian tax payers. Therefore, it is time to instal a 7kws charger at home. It is a rabbit hole.

Vendors
Which ones are reputable from a safety point of view. The key is proper wiring on internal components in which dissemble review of EV chargers online is non-existence. I read a few hobbyist own take part some years ago whilst they commented to an EV charger thread.
So far, a few looks promising

  1. EVNEX – NZ made and owned.
  2. Sevr – Solid cost-effective option with minimal “smart”.
  3. Ocular – looks good and seems to be popular.

Solar integration
My take is that there are two key items:

  1. CT clamp – taps into the wiring so that solar charging is enabled (oppose to charge from grid only).
  2. OCPP – protocol to determine solar energy generated and the ability to charge on solar only, subject to minimal threshold on input from the solar system (e.g. 1.xkws).

Installation
All sparkies, in theory can instal it. Do you go with a vendor installation option or BYO sparky? I see the benefit of a supplied and installed option is the ease on warranty claim. I have no idea how durable EV chargers are (not so much the hardware, but software can take the entire charger down – at one stage, a software update fried an EV charger).
Concern with some random sparky is cabling and able to beautifully hide the wire instead of running conduit to the sun and back.

Would appreciate some input based on the following criteria

  • Charger

    1. Safety– any bad ones to avoid, or good ones to prioritise?
    2. Ability to have solar integration – CT clamp is an absolute requirement, OCPP is a good to have.
    3. Warranty – might be too new of an industry for comments based on long term experience.

    What EV charger do you have a home?

    You've got that all screwed up.

    What? EV charger, do you have a home?

    • Look at mr fancy pants here with their home ownership

  • +2

    If you're getting a proper wall charger installed, you might as well go the three-phase route and get a 22 kW charger installed for a bit more. Bite the bullet once.

    I'll be doing that once I get the recent VoltX battery system deal installed then utilise the 3-hour free electricity/solar to charge 50 kWh home battery, then use that to charge EVs.

    • +1

      No dice. Currently single phase from the street.

      • +2

        Unfortunate. For me personally, I don't see value in spending $2,000+ on installing a relatively slow 7 kW single phase charger. I would rather rely on nearby 60c 75-150 kWh Chargefox while Coles shopping, and top up with granny charger where required.

        • +4

          If you charge for free with excess solar, then this is usually not an issue unless you have a 20+ kw inverter installed. I do have a 22kw ev charger installed but seldom charge at full speed due to wanting to charge with excess solar only. Cost me $699 fully installed as my solar installer installed the charger for me free.

          • @aarick: Yea. A 7kws panel and 5kws inverter. The 7kws will max it out (will dial it down if needed to). Two years petrol should recoupe the cost.

        • +2

          You can get a charger installed for under $1,500 and upgrading to three-phase is usually additional cost (for those who don't have it in place already). Agree it makes sense if it's not much additional cost.

          Definitely rather have a 7Kw charger rather than use Chargefox though. After 9pm I pay 18c KWh and it'll be charged by 6am, whereas a granny charger would take a full day. Not that I do that often, mostly the excess from the solar goes into it. I don't recall a time I had to have the car charged in 3 hours though (and if I did, I'd just go to a fast charger and have it done much quicker).

          It's also becoming awful charging at shopping centres during busy times. Usually half a dozen EVs sitting around waiting to get a spot.

        • No clue where you got the $2,000+ figure from

          • +1

            @TheFreaK: Average of $800-1,200+ for the charger unit and $1,000 for installation quoted.

            • @Hybroid: Hand in your OzBargain license. Even Bunnings does an install for $700.

    • +1

      There are very few cars which can do 22kw on AC. Tesla and BYD both are a max of 11kw and that literally 100% of the current EV market covered.

      • A bit of future proofing doesn't cost much.

        • +1

          What are you future proofing here?

          Even with 22kW charging and an 80kWh battery - do you ever really need to charge it from 0 to 100% in 4 hours?

          Wouldn't it be better to not pay that and goto a super charger once in a while instead?

    • Depends on your exact setup but you won’t pull 22kw from the solar/battery alone, you’ll be limited by your inverter and then the rest will come from the grid.

      7kw charger for an 8kw inverter makes sense for example.

      If it doesn’t cost much extra you can always throttle it and it gives you options at least, but it will be pointless if your goal is to charge off grid exclusively.

    Evnex E2 Plus. Has been running great, with no issues.

    • This comes in more colour options than most new EVs!

    • I have Evnex E2 Core. Great charger but I wish I had bought the plus for the extra cable length

      A home or EV charger? I'm confused

        • +1

          You didn't post a question

      • Yes.

  • I've got the Sungrow AC22E-01 charger, but I'm not totally happy with it. My inverter and battery are sungrow, so it made sense to keep it all together in one ecosystem, but the main issue I have with it is lack of control. I have it set to only ever charge off excess solar, which for day to day use is fine. We are with Globird and get free power from 11am to 2pm, but there is currently no way I can schedule it to force charge during that time. I have to go in and manually change it, then set myself a reminder to change it back before 2pm. Before I had it installed and was charging off a GPO with a smart plug I had some great automations setup to control the charging, now it is vastly dumber. The limitation was only 2.4kW charge rate though.

    It comes with this iHomeManager device that currently doesn't easily integrate into home assistant so I can't control it that way. I suspect as time goes on Sungrow will improve their software, and/or people much smarter than me will get that integration easier to setup for idiots like me.

    • If you have a Tesla there are home assistant integration which you can use.

    • Same scenario as Frashal and also unimpressed with the "seamless integration" of Sungrow's AC22E-01 charger within a Sungrow system. Sparky installed it as per the provided instructions and when it didn't work left me to sort it out. Sungrow support also ignored email requesting support.
      To get it working I installed iEnergyCharge on the phone and configured the charger as a stand alone device. I look at iSolarCloud and then set the charge rate in iEnergyCharge to whatever excess solar is being produced. Test and adjust as required. Not ideal, but it works.

      To address your criteria: Safety - Device build is of high quality, I ran it today for over 4 hours in 37 degree heat without issue. RFID cards work. I've had no issues with the Sungrow inverter and battery since install. Solar integration/software/no OEM support is why I wouldn't recommend this charger.
      Electrician: If you know a good one, use them. If not, compare quotes between a vendor and other sparkys.

  • +1

    For solar-aware charging, I wouldn't bother with CT clamps myself. I'd ensure OCPP compatibility. OCPP not only facilitates solar-aware charging, but can also do other variable charging based on a variety of different control factors e.g. controlling charging based on variable electricity rates.
    (In my case I have a Tesla Wall Connector 3 (TWC) with a Tesla vehicle, and using a Tesla BLE with EVCC software. The combo of these allow me to do solar-aware charging with my Tesla EV, and also orchestrates with my Sigenergy battery system.The TWC is a solid charger, however I wouldn't recommend it to anyone that doesn't have a Tesla EV. It is pretty much a dumb charger).

        @mapax I am glad you asked… I was able to go over some of the old footage and see that Great Great Grandpa Ian did have an opinion on horseless carriages…

    • That looks so nice. Way better than my shitty HA implementation.

    • That looks very nice and neat. Did you build it yourself or is there an existing application that helped? Keen to build something similar for my own setup and would appreciate any helpful information!

  • +4

    I use a regular 10amp charger between 12am and 6am at 8c per kwh (AGL EV Plan)

    So I'm getting about 13 kWh or around 80km range every night for $1.

    • Me too. Wife gets free charging at work and i can get about 30% each night just at this rate. If i need to i can go overnight at 30c kwh(ish) or i was in a rush i would just pop down to the supercharger and fill up at 60c kwh(ish)

    • Same setup and plan.

      Partner does about 100km return a day 4 days a week, so the 6 hours doesn’t fully cover the usage, but including the other 3 days it’s covered in the discounted window.

      Rarely will charge outside that window depending on weekend driving,

    Have had an EV for almost a year, driving about 1200km a month, and have gotten by with a 2kW granny charger off Amazon for $170 - charging with excess solar, during free 3 hours periods, and now overnight if required from a recently installed home battery.

    Have only needed to public DC fast charge twice and that was during overnight trips away from home.

    Effectively has been free to drive for us, even with a not super efficient Mach-E GT (20kWh/100km).

    Recommend trying out a granny charger and seeing if it works for you - it's a low barrier to entry cost wise and is still useful to have if you find you need a 7kW charger installed.

    • We have with the Atto 3. It will be money well spent for the convenience.

    • +2

      15amp power point is a decent upgrade if you are going the granny charger route (and it supports it).

      • Will cost a few hundred to run a wire.

        Might as well spend the 2-3k upfront and get it over and done with.

        • +1

          A few grand over a few hundres is a lot more.

          How many kms per day do you drive? Do you need a 7kW charger? Would 3.2kW suffice?

        • +2

          I think you are missing the point, Do you need a higher charge rate? Or do you just want one?

          • @Mechanist: Just a want for the convenience. A small price to pay. I have seen people getting away with Jolt for some years.

            The amount of money saved via FBT exemption is app $5k a year on average + another $2k on running cost. (Not via novated leasing and holding it as company asset for personal use). Then there is no petrol cost which is app $2k/year for the car replaced.

            The car either not get used at all for a week or two, or will just get used daily to 50-100km/day. A granny charger will just work if remembers to plug it in. 2400w gets 1800w after efficiency lose. So app 100km for 10 hours worth of charging via a 10A socket.

            The current granny charger is permanently in the boot as no one is bothered with it. So whatever installed will be a fixture on the wall with ease of access.

            • @SetTheFaqUp: I have a granny charger myself and just plug it in when I get home. Its no different plugging in a granny charger over the 22kw lead I have in the boot. I leave the granny charger plugged into the wall .

              Its up to you what you want to pay for.

    • +1

      While i agree with the sentiment of trying a granny charger - i'd encourage not to just "grab one off amazon". Go with something with local RCM approval. I got a DETA brand one for $185 from bunnings.

  • +2

    Tesla Mobile Connector Gen 2, plugged into a 15A outlet. Bought the cable organiser to fix it to the wall, and I can disconnect it and take it with me for long trips as a backup. I top up about 25 kWh (a bit less than half battery capacity) by charging it overnight from 12 to 8 am.

  • +2

    Sig 7kw here. Although if SigEnergy had of announced their 50% price reduction of the 12/25kw DC charger earlier, I would have gone that route.

    If you are trying to min/max $$$ with EV, then expect some complexity in setup and perhaps some readjustment of routines/etc.

    On the argument of convenience - One thing I would say is that the Atto has a relatively small battery (~50kw?) compared to most other EV's (80kw), so charging routines are more painful than they otherwise would be.

    • Atto 3 is one - no one really cares, the car just sits there. A byd seal performance - a new daily (2-3 days a week).

      It will cost money, and have accepted this as a fact.

      • +1

        cool, I have a SealPerf as well.

        I would estimate I do about 200km a week, so pretty minimal.

        We got by on the included granny charger for nearly a year, decided on the 7kw purely from "in winter we need to be able to maximise the sun" point of view.

        What if any home solar/battery system do you have?

        • 7kws Winaco + 5kws solaredge invertor. No battery (the maths don't add up).

          In my case, a charge hanging on the wall and easy plug in and will charge at a reasonable speed.

          Otherwise the seal will sit there like the atto 3.

          I known a few that use to drive out to Jolts for free charging and use their granny charger. Not my thing as I appreciate my time.

          • @SetTheFaqUp: are BYD still giving away 7kw chargers?

            If not, I would look at the Solaredge EV charger, it may have some useful integrations with the inverter.

            • @tephra: No. $3k cash

              And no too. Solaredge charger costs an arm and a leg for what it is, as well only a very niche sparkies will do the job.

  • +1

    I've been using the mobile connector that came with my Model 3 since 2022 on a 15A plug. Does the job for me… don't need anything faster.

    I monitor my solar excess via Home Assistant, and have a (toggleable) automation that updates the charging rate to meet the solar excess.

    Terribly complicated and finnicky thanks to Tesla paywalling their web API and having to rely entirely on the local bluetooth API.

  • Sigenergy 22KW EVAC here. My Audi only does 11KW, but at least it's future proofed.

    Not happy with it for excess solar charging (it doesn't work when solar is curtailed during the day, when it's the best time to charge). But I can dial up/down the KW easily on the app easily enough.

    • Have you tried changing the settings from "auto phase switching" to forcing it to operate in single phase mode?

      Seemed to work as a temporary hack for me to get the excess solar usage working properly with the 3 phase/22kw EVAC for me.

      • Yeah I've tried several things; that included. There's been a software update since, so I might do my testing again.

        • Yeah it's been kind of infuriating that it hasn't worked as promised.

    • unless the charger dies first

  • +2

    Zappi

    • Yep, this is what I had installed. Local sparky added it when I first purchased an EV. Works well with battery and directs solar excess as needed. Quality bit of kit, solid app, good reporting - does what I need.

      What you need depends greatly on your home setup, vehicle, and driving/charging times. If my vehicle wasn't home during daylight hours to mop up the solar excess I'd have probably gone a simpler solution.

  • +1

    We just use power point in garage. Works for us. Only drive 500k per month and charge twice a month. Would never go back to ice car

  • Had an EV for 2 years but don't drive a lot so just use a 15A socket in the garage. We've only ever needed to public charge on longer road trips and I tend to prefer/plan for Evie because their fast chargers are more reliable/much faster than ChargeFox. As for solar, check out EVCC. It's some incredible free software that can talk to many inverters and chargers and dynamically adjust charging rates based on your excess solar.

    Some additional gotchas you'll have to be aware of:

    • The Atto 3 only has either 7kW or 11kW onboard AC inverter. Take that into consideration with your choice. And keep in mind that a 15A socket can deliver 3.6kW, so a little over half what a 7kW charger can already do.
    • Related to the above, consider whether you actually need faster charging. You can generally top up 20-25% on most EVs just from a 10A socket from 10pm to 6am.
    • You say you only have 1-phase, so you'll need to see what your maximum inbound amperage is from the street. This will determine whether you can actually support a dedicated EV charger reliably or not. Many townhouses cheaped out on the line into the house (we only have 50A), so we would need a load balancer to install a dedicated charger.
  • +1

    I'm approaching 3 years with an EV and just use the mobile charger I got with the car plugged into 240V mains. Next time I have a sparky in my power box I might ask them to put in a 15A socket but 99.99% of the time home charging at 2.4kw is ample and much more convenient than dealing with petrol stations.

    • go the 32A legality aside

  • I got an EV Switch 7kw charger (the one BYD gave for free last year) for about $499, and a separate sparky (who does EV charger install on a daily basis) to install it.

    It's not solar-ready, unfortunately, but honestly considering Melbourne and only 6.6kw panels, I won't see much benefit.

    • I thought EV Switch is solar compatible? Maybe check out the Whirlpool Forum where there is an extensive discussion. I myself use the same charger and it's benn great (no solar at home just CT clamp for load balancing).

      • It claims to be solar-compatible, but I’m not completely convinced. From what I’ve seen, “solar-compatible” EV charging usually means one of two things:
        1. The charger will happily draw from both solar and the grid, but it’s effectively dumb — it has no awareness of your actual solar generation.
        2. The charger can prioritise or exclusively use solar, with the option to top up from the grid — i.e. genuinely smart charging.

        In my experience, most non-premium, non-branded chargers fall into the first category. That’s why I dislike the term “solar-compatible”: they’re only compatible in the sense that your house wiring is, not because the charger itself is doing anything intelligent.

  • We have an Ocular Home IQ. It was money well spent. With the house facing north (solar panels on the east & west), we can charge our EV3 any time during daylight hours - usually for free from Oct to April.

  • Picked up a ~$250 Ocular Home IQ from that riduclous Bunnings deal (probable price error) in December 2024.

    • Ditto. Probably wouldn't have bothered and stuck with the granny charger but now charge for free with OVO currently and have more choice which electricity companies I can churn to with rather than just sticking with those with overnight plans. EV charging is the bulk of our households electricity use. Churning offers has almost offset the install costs this year.

    I plug that charger that came with the car into a GPO each night, it recharges what I used during the day, I unplug next morning. Can't see how it could get any easier.

    I have Single phase, so went with 7 KW option 32 AMP, I got my EV charger from Amazon under $ 200, with all bells and whistle and colour screen display. Contacted my friendly sparky and he quoted me $ 300 to do the job. He spend around 3 hours and fixed the charger in my garage.
    I signed up with AGL who gives me 8 cents /KW at night for 6 hours.
    I have IM6 plat so 100KW battery so when battery is around 40% i put the car to charge for the 6 hours on schedule charge and by morning i get top up by 42Kw and spend $ 3.36 and that gives me another 250 km range battery.

    I too have solar and belive that i get 4 cents from AGL instead i pay 8 cents so i offset my income against the spending and i have another advantage of running my aircon at night for cheaper price too.

    EV really save the money if you plan well.

    • 4c FIT hahahahaha

      • For smaller solar systems, you don't make enough electricity to feed the car + home on most days throughout the year (especially true in winter).

        The plan is really good if you know how to optimise for it.

  • +1 for the wall plug option. A 15A power point is a solid upgrade.

    We installed an Autel 7 kW single-phase (32A) unit. It works well. But I usually dial it back to 10 to 15A through the car app to match our solar output.

  • +1

    I just use the one that came with the Sealion 7 and trickle charge it when I need to.

    Every now and then I'll spend $25-$30 and take it to a fast charger but it's extremely convenient.

  • I just use the free granny charger that came with mine.

    Never had an issue with battery not being charged in time, but live quite central so don't have to do too many km each day.
