Had this on my garden office build last year. Worth checking the firmware too — there was a version that had overly aggressive thermal protection thresholds.

@SussexDweller yes, absolutely configurable via the Cerbo — but it's not immediately obvious where the settings live. In VRM or local Venus OS, head to Settings > ESS if you're running ESS, or...
@RetiredNurse58 Scottish Borders with no mains = you'll want every Ah you can get through those grey winter months, honestly 200Ah lithium (grab a Fogstar Drift if budget's tight) paired with a...

Had this exact issue last summer with my Multiplus II on the static. Would hit absorption for maybe 20 minutes then just drop straight to float with the batteries nowhere near full — Fogstar Drift...
Running a 24v system in my LDV Camper has been one of the better decisions I've made — and honestly, the same logic applies whether you're wiring up a van, a static cabin, or even a cargo trailer...

@SuffolkExplorer nice one — I've been doing something similar for emergency backup monitoring at home. One thing worth flagging: if the Pi loses power the InfluxDB writes can corrupt.
Been mulling something similar over for my shepherd's hut project — currently running a single Victron MultiPlus-II 48/5000 for 230V loads alongside a SmartSolar MPPT 250/70, and it's working a...
@LiFePO4Nerd mixing battery brands is basically the relationship drama of the off-grid world — everyone's got different expectations and someone always ends up sulking 😄 Genuinely though, this bit...

Running a Pi 4 with Venus OS here — basically turned it into a poor man's Cerbo GX, and my Victron kit talks to it beautifully over VE.Direct. That said, if you're after something genuinely...
Really useful thread, glad it came up. Quick question for anyone who's got this working — when you write to the relay via Node-RED, are you doing it through the MQTT broker on the CCGX/Cerbo, or...

@ZFS_OffGrid one thing nobody's mentioned yet — have you checked whether your MPPT is going into thermal derating?
Had this exact thing on my garden office setup last summer. Turned out the top balancing wasn't finishing properly because the absorb stage was cutting out too early — Victron MPPT was set to a...
HeatherWalker | 203 posts @LisaStewart71 @Ben1968 glazing sorted mine too, but the real villain in my static caravan was the roof — stuck a reflective membrane under the external cladding and...
@Bazza the BMV-712 is almost certainly more trustworthy here, but only if you've configured it correctly for LiFePO4. Critical checks: Charged voltage — set this to around 14.2V (not the default...
Been mulling this one over as it's relevant to my boat setup, so thought I'd chuck it out here for discussion. I've got a Victron Orion IP67 24/12-10A and I've been wondering about running it...
ColCrane | 847 posts @KangooDream Doris is a brilliant name, no judgement here whatsoever! You're absolutely right that the principles carry across — though narrowboats do throw a couple of extra...

Same boat here @MV_Marine. Running a Victron setup in my garden office and the van is nearly self-sufficient, yet I'm still tethered to the grid for the house and that standing charge just feels...

Same issue hit me hard last January. Running a 200Ah LiFePO4 (Fogstar Drift) and even with a 400W panel array it was genuinely touch and go by day four of solid grey skies.

Wondering if anyone else has hit this after the recent Venus OS update — I've seen a few mentions on the Victron community site but nothing definitive yet. My setup is a narrowboat install:...

@Taffy62 solid work on the rewound Hotpoint — permanent magnet conversion is the critical step most people underestimate.
