Brilliant video. Thank you. Finn, for the clarity of your explanation and great annimations. Finally, a great system for three-phase homes. Looking forward to the follow-up video in six to twelve months.
I'm a Victron person through and through for ESS, but looking at this - it seems like a worthwhile system to have installed Simply as a Home ESS system without even considering the EV Charging capabilities!
Actually Finn... we beat you to the title of "Australia's Fastest Home EV Charger" with my SigenStor with 25 kW DC EV charger modules installed a few months ago :)
I hope Sigenergy and similar platforms are massively successful in Australia… because I just installed a 10kW Fronius Gen24 and I want a system like this next time!
Thanks Finn, great video. It would be great in the future to understand the whole setup including solar panels, the total cost and whether it would be possible for city/city fringe homes to go off-grid. I am prepared to make the switch when I know I can buy a car with bi-directional charging and just need a little extra assurance I can make it work. Or the enthusiasm you have!
@@flukeylukey7559 You can start with just inverter, then add a battery later, then add more batteries even later, then add the DC charger even later! Fully modular and totally flexible.... it's just like an expensive lego set!
I was recently quoted $27200 for a 32kw Sigen system with a 10kw inverter. Exceptionally positive reviews about them, but that works out to $680 a quarter for the next 10 years. My winter bill, the highest of the year was $540. I so much want all the benefits but it’s just too hard to justify.
Also worth noting that our batteries are fully modular and independently optimised which means it couldn’t be easier to add more batteries in the future…. Start smaller and add more batteries when the budget allows
If your winter bill was $540, you most likely don't need a 32kwh battery. You could most likely halve it to a 16kwh, which is what I'm looking at, though my bills are higher than yours, you might even be able to go lower to 13 or 10kwh. (Since it's modular, you can start small, then add-on later if needed)
Needs to intergrate with Amber smart shift! Yesterday, in Adelaide, I had my solar curtail to zero output and ran my house and charged my PW2 at negative prices. All I up I was paid $35. I could only imagine what it would be like using this in the same way and charging a car at 25kw as well.
Do you need to have a 3 phase 415v input to the house to get the max output DC output to the car? Or will a single phase 240v input feed the DC charger with the same DC output speed.
What's the legalities if you're only installing these systems for off grid? Surely if it's being installed off grid, you can activate the bidirectional function now?
40kW allowed over East, whereas here in WA maximum we're restricted to 30kW maximum and only 15kW inverter - that's due to the Western Power caveman rules we have here in WA.
We only have single phase (no room on the local transformer for 3 phase). Is there a single phase version of the system and if so what specs are different?).
OK V2G is not enabled yet - due to cars/network not ready... but some cars do support V2G, so Can it do V2H? - i.e. V2G but limited to not exceed the homes usage to keep network happy.
The bit about the whole setup needing to be where just your EV charger is now will rule a few people out I reckon. I didn't see any mention of an IP rating either. Can this be installed outdoors at all?
IP66 rated. If you are limited with space, then we have a longer cable for the DC charger up to 10mtrs.... otherwise you can opt for one of our standalone AC chargers (7/11/22kW) which you can install anywhere but still integrate with the smarts and control of our system.... but you won't be able to do bi-directional charging with our AC chargers
What is the cost of a unit with 6 batteries, no car charger, and can it be connected to a 15kW Enphase solar system? Who do I call for accurate prices and an installation in Western Sydney.
but forgot to mention that the 25kw is not peak because it has a 0.8 leading and lagging power factor so can only get up to 27500va or 30kw for 10 secs
should have mentioned that if got the home max TP home gateway can take 2 inverters for a total amount of 52.6kw of power and 96kwh of storage and 2 x 25kw dc chargers
Good point - but we've learned that not overwhelming people with numbers is important on YT. It's always a balance of how much info you throw at viewers, and what people can absorb.
Japan mandated bidi for all EVs (Leaf, Outlander) made there post Fukushima (2013 on) to help grid resilience. Kia have V2G functionality on the EV5 & EV9 I believe, as does the Polestar4 and some VW models. Most manufacturers will move towards offering this functionality in the coming years and hopefully the choices of bidi chargers will progress accordingly.
@@willhall2468 thanks for replying but what I am trying to determine is does the DC current coming out of the battery to charge the car ever become AC current which would then need to be converted back to DC to charge the car. If not then what is the role of the inverter in this use case? DC - DC voltage conversion perhaps?
I believe that every Nissan Leaf ever sold is capable of bi-directional charging. Shame it has taken everyone else so long to understand that it is a great idea. If all EVs were equipped with bi-directional charging, and were plugged in to an appropriate charger when not in use, there would be fewer problems with grid stability, and there would be plenty of places to put the solar surplus...
I'm on my second LEAF and still on the look out for a cost effective off-grid bi-directional charger to work with my original solar set up. I'm not that keen to buy another 10kw battery for cloudy days when i have a 60kwh battery in the LEAF!
@@SolarQuotes Even in the EU they only list Nio vehicles so far. In North America they go under Point Guard Energy, and they have zero vehicles. So selling hopes and dreams doesn't seem like a good business model.
@SolarQuotes just my thoughts. Nuclear electricity needs 24/7 cashflow. Grid to customers needs 24/7 cashflow. Customers ARE the cashflow. When the sunshines 🌞 With rooftop 7kw PV and 10kwh home battery then NO cashflow to the grid. More customers offgrid for longer With rooftop PV and BV's 100kwh battery and V2G then no cashflow to the grid from all the battery vehicle owners The FREE battery storage with BV's oversized battery parked 23hrs every day and all night long. More customers permanently offgrid.????? Or the grid takes the customers dirt cheap electricity and supplies more industrial customers. The GRID KEEPS ITS CASHFLOW. Happy days. 😊 No nuclear monopolising government money.
9:18 Hey Finn, great video. Just wondering, can you please elaborate on waiting 6 months for cars that can do bi directional charging? I thought the BYD vehicles can discharge via the ccs2 port already. Thanks
BYD can do ~3kW V2L (Vehicle to Load) via the *AC* pins on its Type 2 socket. The SigEnergy DC EV charger in the video is a DC bidirectional charger, so it requires a car that can do DC bidirectional charging via the *DC* pins on the CCS2 socket.
Really struggling to see the benefit of this. 7kW overnight is more than enough for a weekly charge. Can someone enlighten me of an example lifestyle which this would benefit?
DC EV Charger ~$8,600 Retail, 25kW, 3ph inverter ~$6,000, 8kWh battery modules x 3 ~$4500 each: = ~$28,100 - Gateway is another $2k. But the stack is about $28k worth. WIll add a note that its $28k + gateway
@@semsolar9273 It utilises PV, then batteries, then grid if required. You're right, 25kW will be overkill for most resi installs, which is why we also do a 12.5kW DC Charger. But the 25kW DC charger is a great solution for commercial clients.... you can parallel unlimited stacks together to go as big as you want (recently did a winery with 63 stacks / 3MWh), so having a few stacks with 25kW DC chargers would be a good fast charge stop off for those that need to get out on the road quickly
If BVs oversized battery is parked 23hrs every day and all night long, then 10kwh home battery is big enough. Daily drives are very small kWh users. Ezi pezi to top up daily.
This is cool but completely useless. There is 0 and I mean absolutely 0 need for dc charging at home, if you have the money go for it but just know you are throwing it down the drain. It charges 2x faster than a normal ac charger but that takes about 10hrs, so this still takes 5hrs, what’s the point it’s not fast enough to warrant being useful and you don’t want it to be that fast anyway, fast charging especially over 1c all the time will damage your battery. The inverter and battery are fine I install lots of systems like that but the dc ev charger is pointless at best, and anyone who says otherwise doesn’t understand how to properly live with an electric car and has too much money to waste.
For clarity, if you want to understand, just look at the basics. The national electricity transmission grid is the connection between millions and millions and millions and millions of customers and their supply of CASH. $100sBILLIONS cashflow. The nation's 100 years to build, $TRILLIONS infrastructure investment. Obviously the owner's need the $100sBILLIONS in cashflow for this $TRILLIONS investment, its maintenance and emergencies. The real relationship is between the $TRILLIONS grid and the millions and millions and millions of customers and their $100sBILLIONS of cash. 😊😊😊😊
You do realise that only rich people can afford this setup unlike most people who live week to week on what they earn which is a majority of people who you are insulting?
@dikkybee4003 I do not mean to insult. Early adopters will do this first. It will take 20 years to happen. I have gas appliances that will cost to be replaced. When I eventually go all electric. Nuclear promoters are misleading the Australian population, about their solution to worldwide CO2 emissions and their climate change solution.
