What is Victron’s and Victron’s position on this issue, as their interests cannot be overlooked? Bye bye 12, 24 and 48V. Is Victron already on the bridge? ---

Maybe with the Multi HS19, but like Multi RS19 is just a dream for the moment… ---

There will always be some (major) concerns about safety. I have seen “professionals” make same pretty scarey mistakes with HV stuff. Now i shudder for example thinking should DIYers (and i mean the real ones with a lack of fundamental knowlege) taking on installing them as well. Should it be in homes? What needs to change for us all to be safe? > [@alexpescaru](#): > > Multi RS19 They exist 🤣 not mythical. Also can’t wait for them to be (and the market to be) ready and released. ---

My personal belief is that the future will see a massive transition from an AC to a DC based power grid with isolated high efficiency wide voltage range bi-directional DC-DC converters becoming commonplace. All your legacy AC gear will still work as usual connected to your Victron inverter, no matter what gets hooked up to its DC bus. ---

To extend the scope slightly … would a Gen2 EVCS from Victron (with DESS integration 😉) be able to connect the cars DC high-voltage battery via a DC-DC connector for bi-directional energy flow? Or would the link to a Victron based ESS still be AC? And which device would convert the high-voltage DC from the car battery to whatever is needed for the Victron ESS (AC/DC)? A separate device (inverter or DC/DC coupler) in addition to the EVCS? How could such an architecture look like and how would it integrate in the todays Victron EcoSystem? ---

As to what Victron will do all I suspect is that they will move with the market. The key argument for a grid wide transition from AC to DC is the need to facilitate flexible power generation and distribution in much more localized and nested ways than what could ever (technically) be achieved with an AC grid that dictates a common frequency base and flow of power regulation by frequency modulation. It’s not about having enough ‘wired’ transport capacity, it’s about controlling the flow of power. When the whole grid becomes multi voltage bi-directional DC, an EVCS becomes just another power connection.

I would welcome a higher voltage. Victron just brought out the 12/5000 which calls for twin 150mm cables over 5m. Can you say voltage drop!? ---

They have their place and application. I am thinking along the lines of other system integration such as engine charging and dc appliance integration in mobile etc. I would never install that (12vdc) in a house as it is way too inefficient. And for some install locations you would not be able to have the separation necessary for higher VDC to be anywhere near safe. So other VDC systems will not be done away with. ---

HV batteries can be quite dangerous. Like HV PV installations. Some people still don’t understand the meaning of: “DO NOT OPEN UNDER LOAD”. Now imagine working with HV PV. Arcing there gets a new meaning. Scary. Imagine someone without proper protection and training 😬 Not to mention that in a YT movie a home battery building company in NL admitted that at least three people made a short, and one guy flipped the plus and minus in twenty 24V batteries. That they had to redo all of them. ---

I think that Harold is a fellow forum member 😬 “ **Construction of professional home batteries and conversion of my hobby home battery”.** Let me add this note. Harold is a nice guy. His business is booming. Their batteries are really nice. They install a lot of them. In this video he talks about the past. But the message is clear. Anyone can make mistakes. Small or serious. We’re all humans. Learn from your mistakes and move on. ---

Beyond safety considerations, which are obviously very important, wouldn’t these HV batteries be the short-term replacement for current 48V batteries for domestic use? And if so, wouldn’t manufacturers be working towards this goal? [Next page](https://community.victronenergy.com/t/could-the-future-of-our-batteries-be-high-voltage/46610.md?page=2)
