If it comes to market we will all LOVE Victron
⊠and all that in a Systainer like this ⊠great ⊠
We donât know yet whatâs really under the cardboard box⊠
Yeah but if this come to the market this will make a huge difference !
First you can charge at very low power (less than the 1.4kw).
And second you could use your car as storage without additional Hardware !
I just fear that the car manufacturers wil update theirs BMSâs to not allow outward dc currents !
Letâs wait and maybe next year Santa will be nice to us !
NiceâŠ
If we were to guess, some bidirectional DC / DC converters.
Or the hardware of a Multi RS with an additional bidirectional high voltage DC/DC converter, in order to bring the HV DC from the car onto the Multi RS DC bus.
For the beginning and show, only an Multi RS with the battery part adapted for high voltage of the car battery.
The high frequency transformer inside will have different size windings, besides different input capacitors.
This way the VRM is already suited to show all the info.
Of course a high frequency thing⊠Sorry low frequency toroidal lovers⊠
A complete thing will look something like this, below, in order to have the possibility to charge the car from house battery or vice-versa, charge house battery from car, or both from solar, or whatever combination.
Letâs see how long from this to production/selling, as the HS19 is waitedâŠ
Or donât tell me thatâs an HS19 with some small added hardware and/or software to talk, in its ânative languageâ, to the carâs battery, instead to a HV battery⊠Because the carâs battery is also a HV battery.

Thatâs the secret 
If the car manufactureres will do so, then the car buyers will select the cars based on a new thing - if the car is alowing it to be discharged. And then maybe the car manufactureres will change their opinions. I wope we all have the power to convince them, once the bidirectional hardware will be available.

Is nât this the same as âvehicle-to-gridâ or V2G, what is already possible with certain Nissan, Hyundai, Volkswagen, Renault , Cupra, Volvo, etc. EVâs?
As far as I know âvehicle-to-gridâ is not alowed yet, or in pilot fase in most countries, due to regulations, and shortcomings at the network operators.
Yes and no, some of the vehicles you are discussing about are using the internal inverter to generate AC. That inverter must be certified by all the grid operators from all the countries. This product will take DC from the car battery and, with the Victron hardware (already certified), will generate AC. And as you can see in the video, it can do some other extra things, like off-grid operation, switching from charging to discharging instantaneously, PV directly connected to the charging station, etc. There are so many possibilities.

I am not sure of that it will occurr spontaneously for many reasons.
- Choice of a car is not a logical choice
- Temp management of the battery is a huge issue in ensuring a long battery Life and probably the car manufacturers will use this to not encourage this use if they are not 100% sure that their bms is able to coop with it
- The cost of the Ă©quipement will influence it strongly : assuming a home use target (so max 32 to 40 amps on the Ac side ) so some 16 amps charging on a 400v, the Ă©conomies engendered should be significant. The calculation depends on many assumptions (wich are subjective)
If the équipement is able to respond to external demande for keeping the grid stable that would pe « fun » but to my best knowlegde no were in Europe regulators have clearly communicating on this ( i strongly hope they work on a pan european technical / régulation framework but i hope it is not wishfull thinkkng)
Nice thoughts, butâŠ
The Victron universe is already full of all kind of MPPTs (low and high voltages), is full of inverters, full of chargers and so on, all on 48V.
In other words, the Victron users already have most of âextra thingsâ as you name it, because of its modularity.
Building a charging station with all these and most of all, certifying it as a whole, it will be a bumpy and long road.
If I were you, but thatâs just my opinion, I would design a stand alone 5kW bidirectional DC/DC converter, like the Orion class, only that it will be 48V DC to 350-450V DC.
Once this, you will just plug it on the 48V DC bus and with a proper control of the car battery, it will be just like adding another battery to the 48V bus.
Charge the car from already existing MPPT(s) on the system, draw from it and make AC when needed, inject the AC and so onâŠ
All with the already existing hardware.
You just need to design a new, high voltage, bidirectional Orion-like DC/DC converter.
Thanks for sharing your opinion!

What about cars with 800V architecture, currently Victron does not have an official product out there, just announcements of a HV string inverter.
I like these ideas. But I would like to add that a system voltage of 560Vdc (3 phase 400Vac rectified) would make a lot of sense. That would open a world of possibilities and markets.
One could think of industrial users with grid independent machines. A central rectifier(bi-directional as option) for the grid connection, MPPTâs feed to this DC bus from the roof, DC-DC battery chargers to 48V for low voltage applications, lighting etc. and DC-DC chargers for big HV storage. Motor drives will be able to DC couple on this bus to drive the machines. That happens already within one machine (overhead cranes for example). One regenerative rectifier with a drive for every motion axis. And off course DC charges for the electric vehicles.
Next market will be electric ships., to bring it closer to Victronâs roots. A 100kW e-motor running on 400V requires a lot less copper to connect it to the drive system compared to a 48V motor. Drives down losses as well, which makes a boater happy. Halfway the Atlantic you wonât find a 800V DC quick charger.
Iâm taking my home as an example; my grid connection is 3x25A 230/400V. I would like to connect my house to a single phase Victron MP-II 6k5 which would be enough for my household. Our energy supplier would like to see a power imbalance of max 5000VA in both directions. So a 3ph. 48V controllable charger would be a welcome addition to the device list. Or a 560Vdc to 48Vdc charger. I will build my own rectifier in that case. A 16A 3 phase diode module costs about âŹ40. 2 pieces of 400V capacitors in series as buffer about half of that. Thatâs 11kW worth of rectifier.
Sorry for the rambling, but this is something thatâs been crossing my mind for quite a while now. Alex gave me a sliver of a hook.
Going by the recent video, the new Victron HV combo will support 800V (maybe even 1000VâŠ) not 400V.
They said this was to effectively get a jump on the market since thereâs plenty of 400V kit out there, and presumably to take advantage of all the 800V system development work and components (including batteries) being developed for newer EVs and ultra-fast chargers.

I was hoping to get a confirmation from Lucian that he bi-directional DC charger would support that and thus indirectly that the 800-1000V DC-DC converter is ready to be put on the market as a part of MPPTs or inverters but that did not work out 
The problem is that thereâs not going to be much market for a LV-to-HV (e.g. 48V-800V) DC-DC converter, bidirectional or not, because the market driving 800V kit is the high-power one â 30kW or more in a single unit, lots of units paralleled up for even higher powers. 48V is simply too low voltage for this, the currents would be unmanageable⊠
In contrast there is a big market for grid-battery-AC mains conversion, where low voltages are simply nowhere to be seen â and given the rapid emergence of new 800V components/batteries/systems for EVs, it makes a lot of sense for Victron to leapfrog 400V and get a jump on others have already invested a lot of time/effort/money.
And donât forget that boaters are a small part of this market, by far the biggest and most rapidly growing one is domestic/industrial power/off-grid/backup â boaters get to ride on the coat-tails of this market for free, thereâs no way marine apps would justify such developments.
Itâs a bold move but â assuming it pays off! â it could establish them as a market leader. Which is what the video saysâŠ
But for vehicle to home purposes like in this demo you donât need that high current, 11kW is already too high. Weâre not talking about 150+kW high speed DC chargers here where you would need 3000 Amps. An RS 450/200 provides 200A at 55V to reach that 11kW, that is fine. a 11kW HV âRS 800/200â or âRS 1000/200â would still only need 200A on the 48V side per DC-DC converter. No one is asking for an MPPT or inverter that can do 50kW or so, where would one even need that in a household situation?
I just watched the demo video (with auto-translated subtitles) and itâs honestly pretty amazing.
My guess is that the unit under the box is either a modified (or possibly even unmodified) prototype of the Multi HS19, which hasnât officially been released yet. If thatâs correct, then this video makes the upcoming HS19 release even more exciting â because it strongly suggests Victron is already preparing a full ecosystem around high-voltage / EV integration.
What I also find very interesting is the strategic position Victron could take here:
-
I expect Tesla will end up offering something similar, but as a proprietary closed ecosystem (Tesla car â Tesla inverter/charger â Powerwall).
-
Victron, on the other hand, could become the universal âintegration layerâ for multiple car manufacturers and other solar-related equipment
That would be huge â because it means the solution wouldnât be locked to one brand. It would be more open, more flexible, and potentially allow almost anyone (installers, integrators, even other manufacturers) to participate in the system.
From what I understand, this might become an official Victron product, possibly a hybrid concept:
-
HS19-based inverter/charger hardware,
-
combined with an additional interface/board that enables connection between the inverter and the EV HV battery via the DC plug
If thatâs what Victron is building⊠I honestly canât wait. This could be a major step forward.
By the way â so far Iâve only seen this concept demonstrated in this Romanian video.
Does anyone know if there are any other sources online (video / podcast / interview / blog post) where Victron presents or discusses this HV / EV integration concept?
Or is this currently the only public video that mentions (or indirectly shows) this still-unreleased product?
One more thing - can maybe one of the moderators change the title of this thread to be more specific than âHuge news from Victronâ.
This is such a cool concept and it would be nice if more people chimed in and rather than starting new thread, we can keep it in here but the existing title doesnât help.
