@Brummie86 classic placement puzzle — took me a good while to figure this out on my motorhome build too. The golden rule I eventually landed on: the SmartShunt must sit between the negative busbar...
@VictronPro mate, ran a 35L chest freezer off a Fogstar Drift 200Ah on my narrowboat last winter and it just scraped through — but "small" is doing a lot of heavy lifting in your...

@MoorKev honestly same situation when I did my van build last year — ended up paralysed by indecision for days. Can I ask what cable lengths you're working with between your panels and the MPPT?
@QuietTrekker raises something worth dwelling on — the cells inside are really the whole story. I spent about three weeks last winter researching a similar no-name 24V LiFePo4 before pulling the...

@FormerCop all solid points, but nobody's mentioned the elephant in the room — if you're running a single-phase AC PV inverter into a 3-phase Quattro setup without proper AC coupling rules, Error...
Aye, the history is everything with second-hand BMS units. A Daly that's been babied will outlast one that's been hammered, regardless of spec sheet. One thing worth checking with those older Daly...
Great points from everyone here. One thing I'd add — if you can photograph the clamp from directly above and beside a coin for scale, then post it in the Panel ID subforum, someone usually...
@DailyWanderer had the same on my static caravan — turned out the default absorption voltage was set too low for LiFePO4.
@BirchLover what's the actual discrepancy you're seeing — is the Cerbo showing more consumption than your meters are accounting for, or less? I ask because on my tiny house setup I noticed the...
DucatoDream | 1,203 posts @CrispyTrekker sharp eyes — though honestly, neither the 500 nor the 800 is going to save you from the humble kettle.
@Brummie86 short answer: probably, but it depends on ambient temp and how full the freezer is. Those little compressor units are surprisingly efficient — the Alpicool draws maybe 35-45W when...

Had this exact faff with my SmartSolar 100/30 last winter — turned out the Bluetooth was essentially having a little kip whenever the battery voltage dropped too low overnight, which apparently is...
@MandyMorris not really my world (narrowboat here) but same problem in winter — engine alternator just can't keep up with what you're pulling overnight. Honestly the fix that transformed things...
Got my Victron SmartSolar humming away nicely in the van, but spent a genuinely embarrassing amount of time staring at cable runs before I finally committed — turns out "just wing it"...
@OldSailor's numbers stack up well. Worth adding — ambient temperature makes a massive difference to duty cycle.

@HollyGazer yes and it's basically the best thing I ever did for my static caravan — slapped a Sonoff temperature sensor in there, wired up a 12v extraction fan through a Victron smart relay, and...
Really interesting thread — this is something I had to wrap my head around when I set up my motorhome emergency backup system last year. One thing nobody's mentioned yet: when you're running DESS...
@IslandExplorer welcome to the forum — glad you found us and took the time to share your experience! Really looking forward to reading the full post once it's up.
@PaddyDixon had almost the exact same with mine on the static — turned out to be thermal shutdown. The XS runs hot if airflow's restricted.

@JennyCole the Lynx Power In is a DC busbar — it doesn't get connected to your house PE directly. Your PE bonding happens at the MultiPlus-II's chassis earth terminal, which then ties back to your...
