Help I need firmware 2715563.....victron has done this to me again with unreleased firmware

Classic Victron: the firmware lottery you never asked to play. 🎰

Had almost the exact same headache last winter on the narrowboat — MultiPlus arrived with a firmware version that sat in some sort of weird limbo between what VictronConnect would acknowledge and what was actually stable. Couldn't go backwards, couldn't go forwards without breaking AC input functionality, just... stuck.

The 2715563 situation sounds painfully familiar — you're essentially held hostage by a release that exists in the wild on physical hardware but hasn't been formally published. Victron's firmware versioning has always felt like it was designed by someone who actively dislikes narrowboat owners and shepherd's hut dwellers specifically.

A few things worth trying if you haven't already:

• Victron Professional portal — sometimes firmware versions appear there before they hit the public VictronConnect rollout
• Contact your dealer — if you bought through a Victron authorised distributor in the UK, they can sometimes request firmware directly from Victron
• Victron Community forum — the devs do actually lurk there and occasionally drop files in threads, proper old-school style

The AC input issue with 564 s98 is a known problem or a new discovery? Because if it's documented somewhere that'd at least give you ammunition when you contact support.

Genuinely baffles me that a company charging MultiPlus money ships units with firmware that has no clean upgrade path. My Fogstar batteries arrived better documented than this.

Anyone else currently running a unit that came out the box on 563? Curious whether this is a batch issue or if Victron are just having a moment again.

@OffGridGeek mate I feel this deeply 😅

Had the same drama setting up my garden office last year — Victron kit arrived and VictronConnect just stared at me blankly like it had no idea what it was looking at.

Turned out the unit shipped with some pre-release firmware that hadn't hit the public portal yet. Had to dig through the Victron Community forum (the official one) to find a beta firmware thread where someone had posted a direct download link.

Worth checking there if you haven't already — the Victron devs actually respond on that forum which is rare and genuinely useful.

One thing though: don't just grab any random firmware link people post. Stick to anything linked directly by a Victron staff badge. Flashing dodgy firmware on a MultiPlus is not a fun afternoon.

Is there a way to check the firmware version before you even take it out of the box, or does that require connecting to VictronConnect first?

Wondering if this is something that could be flagged at point of sale — like, should dealers be shipping units pre-updated to a stable release? My Fogstar battery setup arrived perfectly configured but then the Victron MPPT I paired it with needed an immediate update before it would play nicely with everything else.

@OffGridGeek did Victron support actually point you toward a specific stable version, or was it just trial and error? Feels like there should be a clearer published list of "known good" firmware versions for each product somewhere on their site rather than having to dig through the Victron Community forums piecing it together from other people's bad experiences.

@OffGridGeek oh, this takes me right back to commissioning the narrowboat setup last spring — standing on the towpath in the drizzle with my laptop balanced on a windlass, wondering why VE.Configure was refusing to talk to the MultiPlus properly.

To answer @George1972's question directly: no, you genuinely cannot check the firmware version without connecting via a MK3-USB interface or VE.Direct cable and firing up VictronConnect or VE.Configure. The box tells you absolutely nothing useful. Your only pre-purchase option is to ask the supplier which firmware batch they're currently shipping — some of the better UK dealers like Bimble Solar or Offgrid Tech will actually know.

The real lesson I learnt the hard way: always budget time for a firmware update session before you need the kit in anger. Emergency backup situations are precisely the wrong moment to discover you're on an unsupported version.

@George1972 short answer: no, not really. You need it powered up and connected via VictronConnect before you know what you're dealing with.

What I do now on the boat is grab the MK3-USB adapter first before touching anything else — at least then you're not scrambling around trying to find one when you realise the firmware's nowhere near where you need it.

Worth bookmarking the Victron firmware repository too. Doesn't tell you what's in the box obviously, but at least you know what's current and what's lagging behind before you start a job.

The real fix is Victron shipping with consistent firmware but... yeah, not holding my breath on that one 😅

@BirchTrevor is right, and it catches people out every time. What I'd add from bitter experience on my narrowboat — if you're buying from a smaller UK dealer rather than a big distributor, ring them first and ask what batch they're holding. Some of them have genuinely no idea, but occasionally you'll find one who does.

The other thing worth knowing: even if you do get a problematic firmware, Victron's beta program through VictronConnect can sometimes get you an earlier stable release. It's not advertised loudly, but it exists. Had to do exactly that with my MultiPlus-II to get ESS behaving properly before the official fix dropped.

Frustrating as it is, they usually sort it — just not on your timeline.
