A setup that will be of interest to those with an EV with V2L capability, that are looking to be able to use their EV as a backup power source. Some photos of an off-grid house system, 3-phase 30kVA, with AC-In wired for a backup Genset (future if needed), AC-Out 1 for general loads and AC-Out 2 co…

Hey @PeakShaving could I ask you a couple of questions? I’m in Australia, and I would like to achieve V2L from my BYD Seal into my system. I’m leaving fully off-grid, and I would prefer to use my car as a backup power source, rather than having a noisy diesel generator. Thanks in advance!

Hi Carlos, sorry for delay in responding. Yes certainly. Still learning from the Pilot system we done, certainly works. The comming winter months will determine if V2L negates the need for a Genset

The solution is to install a separate Smart Shunt between the separate Multiplus acting as the charger and the common DC Busbar. It’s connected to the main system Cerbo via VE.Direct and you can chose type as AC Charger in the settings instead of battery monitor. Hope this helps

Hey Ryan, I have two questions for you: How is the system behaving after these months? Now that winter is in, is it still looking like the V2L could effectively replace the generator? Regarding your observation on being essential to install a 230Vac/230Vac isolation transformer, I think I und…

Hello Ignacio, Apologies for the delay in replying. Yes the V2L MPII Charging setup is working very well. EV is able to discharge at around 3.4kW continuous, which after efficiency losses in the MPII outputs around 3.1kw to the common DC Busbar / Battery Bank. It’s likely a backup generator will …

Thank you again for the info Ryan, I take good note of your advice about the isolation transformer. Have a great 2026!

Very nice set-up, my compliments. The EV is solely used as back-up, right? Or can you also charge it in this set-up? In other words: this isn’t bidirectional, right? Sorry if it’s a stupid question.

@Palindroman Thanks for your question. No not stupid at all. Yes can also change the vehicle from the system too. A Victron EVCS has been installed providing upto 22kW Charging Power. It’s not bidirectional, however archives similar end result. There’s separate connections installed for charging …
