@JA_Solar was about to say the same thing — there's actually a middle path here that saved my shepherd's hut setup. I had a lone Fogstar Drift sat in the corner and rather than binning it or...

@Mel1980 😂 accurate Worth mentioning — if you're going the VE.Direct route, the Cerbo has 4 VE.Direct ports built in, so no hub needed for most setups.
Really useful thread this — I had the exact same headache with my motorhome emergency backup setup last year. One thing nobody's mentioned yet: even with Hub4Mode set correctly and External...
Been running a Pi 4 (the 2GB one I had gathering dust) connected to my Cerbo GX via USB for a few months now and it's been rock solid for logging locally.
Got a bit confused with the Orion XS settings in Victron Connect and hoping someone can clarify. Running it in my shepherd's hut to charge a 12V lithium bank (Fogstar Drift 100Ah) from the vehicle...

Hey @WonkyHermit — narrowboat life, I feel that! The maths is brutal isn't it. One thing worth considering beyond raw capacity is your usable depth of discharge.
Bit of a strange one this and wondering if anyone else has hit the same wall... Running a Victron MPPT RS 450/200 alongside a modest battery bank with a CAN-connected BMS.
@BordersNomad the thing that finally broke my October paralysis was imagining February me — properly cold, properly skint on electricity, watching the solar gauge flatline at noon.

Had this exact headache with my tiny house setup last winter — Victron NG bank feeding an Orion XS, and the damn thing showing as "non-BMS-managed" in VRM no matter what I tried with the...

What @BatteryRay said about transfer switches really resonates — I went through exactly this when wiring up my garden office last year. I ended up running a completely separate circuit from a...
BoatLouise | 156 posts | ⛵ Solar Boat Convert @HannahDavies85 ooh Node-RED on the Cerbo, I keep meaning to go down that route but it feels like a rabbit hole I won't climb out of 😅 On my boat I'm...
@SaltyMechanic the Victron update cycle is just "break it, acknowledge it, fix it in six months, break something else" on an eternal loop — meanwhile my Cerbo's sitting on v3.64 like a...
Been scratching my head over this one for a few days now and could do with some guidance from people who actually know their stuff. I've got a pair of 200W panels wired in series giving me roughly...

@24V_Queen's point about the flat voltage curve is the key bit here. I learned this the hard way on my old Ducato — spent a week convinced my Fogstar cells were dying because the voltage looked...

Been having this exact issue with my Multiplus II in the shepherd's hut build. It blasts through bulk, hits absorption for maybe 20-30 minutes, then decides it's done and drops to float — but the...
So this one's been niggling at me for a few weeks and I finally decided to post about it. Running a fairly beefy setup in my static off-grid place — two Multiplus-II 5000s in parallel, a Victron...

Not directly relevant to motorhomes, but I've been wrestling with exactly this problem planning my shepherd's hut build — space under the sleeping platform is tight. One thing I'd add: have you...
Ran a Fogstar 100Ah on my narrowboat for two summers trying to power a 12V compressor fridge overnight — spoiler: the fridge won.
@SIE_Electric Worth adding that the ZKE EBD-A20H is a solid choice for proper discharge testing — handles up to 20A constant load and logs data via USB.
Right, so I finally ripped out the old 75/15 and slapped in a 100/30 on the boat last weekend. Difference is already noticeable — panels are actually doing something useful before 10am now instead...
