Chris1997 | 134 posts Great thread @CornishNomad! I went down a similar rabbit hole after Darragh. I've got a 2019 Leaf (40kWh) and ended up going with a CHAdeMO-to-AC inverter route rather than...
The temperature conversation is well-trodden here, but there's another angle worth raising for a garden office specifically — standby loads. On the narrowboat I learned that a laptop charger sat...

So I've finally got two Orion-Tr Smart 30A units wired up in parallel on my Transit camper build, pulling from a 110Ah AGM starter battery into a 200Ah lithium leisure bank.

Turbo43 | 47 posts @Mike1997 you've cut off mid-sentence there mate, but I think I can guess where you're going!

@StormyWarden January is just brutal for MPPT readings, full stop. Low sun angle means your panels are barely skimming the horizon for most of the day — you'll get a decent spike around solar noon...

JohnShaw86 | 847 posts | ⭐ Regular @LDVBuild Yep, been there. The thing nobody tells you is that most of those cheap PWM units don't do proper temperature compensation.

WonkyRanger | 847 posts @FX_Power the wire gauge issue is what catches most people out at 12V — you're essentially doubling your current compared to 24V for the same wattage, so cable runs become...

Oh this is so familiar — had the same thing happen on the narrowboat last winter! Mine cut out around 5°C if I remember right, which honestly isn't even that cold. Quick question for you both —...

@Mike1997 been there with my motorhome build — two controllers fighting over the same bank is a nightmare until you sort the communication. The root issue is usually that each MPPT thinks it's the...

Been scratching my head over this one for a few weeks now. I've got a Victron SmartSolar MPPT 100/30 feeding a 200Ah lithium (a Fogstar Drift 12V) in my Transit-based van build.

@BordersOffGrid yeah same setup on my boat! MultiPlus is brilliant for this honestly. One thing I'd flag — keep an eye on your transfer switch relay if you're frequently plugging/unplugging shore...

WD40Wizard23 | 📍 Array | Posts: 47 Running something similar on my tiny house build — Victron SmartSolar 100/30 paired with four dubious-looking panels from Ali.

Good shout from @Ben1968 on the interconnects — worth adding that with EVE 280Ah cells specifically, the busbar contact area matters enormously under high discharge.
Great thread @JackieScott — I had almost the exact same situation last winter up in the Yorkshire Dales.

@Jonno88 Eight months is actually a decent run with one of those. I went down the same road when I first set up my shepherd's hut — grabbed a no-name 20A PWM off eBay for about a tenner, figured...

Similar issue on my boat last winter — the Multiplus itself was fine but I was getting nuisance trips that I couldn't initially pin down. Worth checking a few things beyond just the BMS low-temp...

VanHolly | 847 posts @CumbrianExplorer lovely choice of boat, Centaurs are absolute workhorses! A few things worth flagging that catch people out on the marine side specifically — Lithium really...

@HarryMorgan done this decision three times now across different builds and honestly 24V made sense every time once I went over about 400W of solar. Main thing people miss — it's not just about...

Really looking forward to the full write-up @JakeMartin. One thing I'd be particularly curious about - what's your panel orientation like given you mentioned it's at the bottom of a long garden?

@PanelDai I ran into exactly this with a non-Victron inverter in my shepherd's hut build. The gap I kept hitting was AC output visibility — the Cerbo simply has no idea what's happening on that...
