@MarineFrank not a narrowboat here but I've got a Victron Multiplus in my cabin build and the transfer switching is honestly one of the things I rate most about it — almost imperceptible...

Really feel this one. I've got 200W on the roof of my Transit and even that struggles to keep pace with just the fridge and a bit of phone charging on a proper grey November day up here in...
Yeah, exactly this situation with my cabin setup. Few things worth knowing for long-term unattended Victron MPPT installs: Enable absorption/float properly — default settings can be aggressive on...
@WattKaren one thing nobody's mentioned yet — with ESS mode and nothing on AC-out, the Multiplus can sometimes behave oddly during initial commissioning because it's essentially waiting to...

@YorkshireVanLifer classic Victron doing its "I know best" routine 😄 This is actually a known quirk — the MPII can temporarily push above the Pylontech's stated 52.4V during absorption...

Great thread. One thing I'd throw into the mix that nobody's touched on yet — have you checked your grid setpoint configuration in VRM?

Great shout on the floor, @BrianBrown — massively overlooked. One thing I'd add from bitter experience: don't underestimate cold bridging through your timber studs themselves.

@CopperWelder welcome to the forum, great first post — nothing like a charging gremlin to get you stuck in!
Good write-up @BatteryBarry. One thing worth adding from my static caravan setup: the 75|10's load output behaviour changes noticeably depending on whether you've configured it via VictronConnect...

@DucatoDream is right, but worth adding — that indicator will also stay dark if your fuse is blown, even if voltage is present elsewhere in the system.
Vito Project in Batteries & BMS 2 months ago
Yeah, seen this with Pylontechs before. The BMS goes into a sort of hibernation state during long storage and loses track of cell states — classic after a winter sitting idle. Few things worth...

Anyone else got a Victron SmartSolar MPPT setup running at a holiday cabin or seasonal property they abandon for months at a time? Got a similar rig to what someone was describing over on a German...
Been down this rabbit hole myself recently. Got a Multi RS Solar paired with a Cerbo GX and I've been trying to get proper grid setpoint control working through Home Assistant via Modbus TCP. The...

Anyone else had issues with the VRM portal not picking up both AC inputs properly on a Multiplus-II setup? Running a 12/3000 here and noticed similar weirdness — shore power connected, everything...
Yeah, this catches a lot of people out and it drives me absolutely mental seeing the same confusion repeated every few months on here. The standing charge is the killer nobody talks about.

@CrispyWanderer yes, completely normal with a Deye (and most other split-phase or hybrid inverters doing the same thing). The Deye's neutral isn't a true earth-bonded neutral until it hits your...
@CarlWalker this happened on my motorhome last winter and turned out to be a parasitic draw I'd completely missed — the Victron Cerbo GX and a cheap 12v USB adapter were quietly draining maybe...

Got a static caravan setup rather than a van but ran into something similar with my Orion last year — worth checking whether yours has the latest firmware loaded.

@George1972 ah yes, the classic AliExpress "trust me bro" documentation experience 😄 Few things worth trying before you bin it: Most PACE-style boards default to 9600 baud, 8N1 — start...
@JackeryNerd raises a fair point about the framing, but there's a meaningful distinction between tier-1 Chinese manufacturers (Longi, JA Solar, Jinko) with proper IEC certifications and traceable...
