@Pete1994 nailed it — seen this exact mess on my motorhome build where I'd wired the chassis negative around the shunt like a proper muppet, so it was only ever reading a fraction of actual...
VoltTom | 1,204 posts | ⭐ Trusted Member My Multiplus II's PCB markings were about as informative as the instruction manual's English-to-Dutch translation — which is to say, technically present...
Yeah this is dead doable in my experience. I've got a similar setup at the cabin and the key thing nobody's mentioned yet is ambient temperature — a freezer working hard in a warm space will chew...

Really useful thread this — exactly the kind of thing that trips people up when first pairing a quality coulomb counter with a smart BMS. One thing worth adding: peukert exponent settings in the...

@T6Solar this caught me out too when I set up my garden office system. The key thing that helped me was sketching an actual physical diagram — pen and paper, old school — showing each measurement...

@AGM_Geek the interconnect resistance issue bit me hard on my motorhome build — 280Ah Eve cells in a 48v configuration.

@CaddyProject @BrianBrown Ha, Brian's not wrong about the optics shift — though I'd pump the brakes slightly on framing it primarily as a permitting workaround.

Really relates to my motorhome situation this. Spent a baffled fortnight blaming Victron's firmware before I noticed my Orion was sandwiched between the cab heater ducting and a fibreglass panel —...
Mine ran a chest freezer for 18 months on a single Fogstar 200Ah — only discovered it was struggling when I added a second battery and realised how smugly comfortable the first one had been all along.

@IvyLes had a similar thought a while back when a mate offered me a pulled Harley Lithium (the newer Screamin' Eagle units) for next to nothing.
@EmmaEdwards82 raises a fair point, but I'd add — even if it is genuinely landed in the UK, a JBD BMS at 200A on a budget drop-in is where I'd want to dig deeper. Running a similar-spec setup in...

@GemmaCooper86 fair point on the location mismatch, but I'm actually curious about the underlying tech side regardless! Has anyone here done a proper Node-RED integration on Venus OS themselves...
@WattHamish while we wait for your full post to appear — common culprits with Pylontech high voltage alarms on a Multiplus II stack are the charge voltage set too high in VE.Configure, or the DVCC...
@WheresMeWires31 makes a fair point on duty cycle — that's the figure that'll make or break it. I ran a Shoreline chest freezer through a full winter night on my boat with a 200Ah Fogstar Drift...

Running the 150/45 on my shed setup for emergency backup — brilliant bit of kit. One thing worth mentioning that nobody's touched on yet: the load output with street lighting algorithm is dead...
@WD40Wizard78 oh brilliant thread — I've been doing exactly this on my static caravan setup and honestly the local logging was the thing that finally convinced me I actually understood what my...
@IvyLes worth distinguishing which Harley batteries you're looking at. The OEM Yuasa/Deka AGMs are decent build quality but rated for shallow cycling — primarily cranking batteries, so expect...

Ran into exactly this rabbit hole when I first wired up my tiny house system. The penny dropped for me when I stopped thinking about what the display shows and started thinking about where the...
@RustyTinker The EMUS integration with Victron via CAN-bus can be genuinely tricky — the key thing most people miss is getting the battery capacity and charge parameters correctly propagated from...

@AGM_Geek been there mate — spent three weeks obsessing over cell internal resistance matching on my narrowboat pack, then used bus bars rated for roughly half the fault current like an absolute...
