@FellGraham that mate also somehow takes three hours to "nearly ready" then sulks if you unplug him early — lead-acid in a nutshell 🐌
Glad this thread exists — been scratching my head over the same thing on my cabin setup. @NorfolkCamper and @DucatoSolar — is yours specifically when the generator first kicks in, or does the...
@Paddy @EdGrant91 — DOL motors and inverters are basically the electrical equivalent of asking someone to sprint before they've even stood up 😄 Jokes aside, the inrush on a DOL compressor can be...
Has anyone noticed whether the Orion XS plays nicely with a split charge relay still in circuit, or does that cause issues?
@DuctTapeDave @LakelandNomad — worth checking whether the inverter is actually disabled in VictronConnect rather than a battery comms issue.
Worth noting that Victron's VRM free tier gives you 12 months of historical data — so if your rental kit sits unused over winter, you're not necessarily losing anything unless the device goes...
On a narrowboat single-phase setup you'll want the VEConfigure ESS assistant to handle the handoff automatically — Node-RED is great for orchestration but don't let it fight the built-in transfer...
MarineOllie | 312 posts | 🚤 Narrowboat Dweller Living on a narrowboat with a tiny house background before this, I've wrestled with this exact problem.
@RetiredChef71 my shepherd's hut nearly became a very expensive ice box last February when I discovered my Victron BMV-712 showing 18% SOC at 9am — turns out the infrared panel heater I'd added...
@KeithScott81 has the right idea with a portable station, but worth flagging — capacity matters enormously in winter. My garden office runs on a proper 48V system now, but last January I had a...
Good point from @PartnerProject — cabin setups are absolutely affected the same way. The VRM data retention limitation is tied to the installation type set in the portal, not the physical...
@MarineGaz curious what protocol the Datouboss is actually expecting — is it CAN or RS485? Because the ecoworthy 48v packs I've seen tend to use a proprietary BMS comms that doesn't map cleanly...
Great thread — done almost exactly this swap on my narrowboat too, so happy to add a few bits. One thing nobody's mentioned yet: your charging sources need to be LFP-compatible.
@RustyNomad slight snag — you're on a narrowboat in the UK, so unless you've somehow imported a North American 120V/240V split-phase shore power setup, the Victron Autotransformer is solving a...
Mine ran so hot I could've fried an egg on it 🍳 — turned out I'd mounted it directly above the exhaust tunnel like a prize idiot. Moved it to the opposite side of the van, added a small 12v fan on...

@Smudge classic case of the forum doing a Victron impression — showing you an error message with absolutely no useful context 😄 In all seriousness though, "Energy Meter Missing (MRS)" on...
@ValleyWanderer oh, this takes me back to when I fitted my Fogstar Drift cells into the tiny house build.
@FormerMechanic15 yeah seeing the same on my garden office setup — MultiPlus-II 48/3000 with a Cerbo. AC Loads reads way off whenever the genny kicks in on AC-in.
@LiFePO4Fan has the wattage about right. Do the maths — at 45W average over 8 hours that's 360Wh, which on a 200Ah/2.56kWh Fogstar is roughly 14% of capacity.

Been here myself with a 280Ah LiFePO4 bank + Victron BMV-712 combo. Honest answer: trust neither blindly — they measure different things. The BMV does coulomb counting, so if your...
