Running a compressor fridge overnight on a single 100Ah leisure battery is genuinely borderline, and I learned this the hard way on my motorhome before I expanded the bank. A typical 12v...
Been scratching my head over this one with my van build and thought it'd be worth opening up a discussion here. I'm running a Victron Orion XS 1400 for DC-DC charging and trying to get the remote...
Ha, @BevJackson64 you've got us all on tenterhooks here! 😄 As the others have said, do finish the post off — but while we're waiting, I'll add that with parallel Fogstar Drifts I'd be looking...
@LH_Marine hits on something I learned the hard way fitting out my boat — continuous draw is the silent killer.
So this one's been rattling around in my head ever since I started speccing out the next phase of my van-to-tiny-house transition... I'm looking at AC-coupling a Victron MultiPlus-II with an SMA...
@CharlieStevens85 had this exact headache with my Multiplus II and a bank of Fogstar Drift cells. Once @PennineNomad's tail current fix is sorted, check your absorption voltage too — if it's set...
Been scratching my head over something similar for my shepherd's hut build and wondered if anyone's tackled this. I'm running a 12V 100Ah Fogstar Drift LiFePO4 as my main bank, but I need to...

Bit of a rabbit hole this one, and I've been down a similar path with my motorhome setup so thought I'd chip in. Running a pair of Multiplus II 12/3000s myself, originally with four 12V batteries...
What's the actual voltage range you're seeing from your panel at the input side? That's the bit I keep getting stuck on with my shepherd's hut setup — panels can spike well above their rated Voc...
Blimey, it's like someone raided a Victron warehouse and decided their narrowboat refit could fund a small holiday — half this stuff is sitting in my engine room doing absolutely nothing too, so I...

@HeathGazer this is almost certainly the ESS assistant version mismatch that @BatteryAlan alluded to — but specifically, post-update Venus OS sometimes resets the Minimum SOC and Grid setpoint...

Just to add a practical note to what @ExSquaddie49 and @LochLover have mentioned — with different roof aspects you'll likely find your MPPTs are rarely all peaking simultaneously anyway, which...
@HazelDawn one thing I'd flag that often gets overlooked on small arrays like yours — make sure your SolarSense 750 settings account for the actual installed tilt angle and azimuth deviation from...

@ShortCircuit 200Ah for a garden office through a British winter was always going to be marginal at best.

@RetiredNurse58 Worth doing a proper load calculation before committing to a size. Roughly — add up your daily watt-hours (lights, fridge, phone charging etc.), divide by your battery voltage, and...

Got a Pi Zero 2 W running Venus OS in my shepherd's hut — handles VE.Direct from my Victron SmartSolar no bother and costs next to nothing compared to a Cerbo. That said, the real game-changer for...
@RustySkipper narrowboats are a great use case for lithium — the weight saving alone is worth considering given how much lead you'd otherwise be lugging around in the bilge.
Good shout from @MuddyFisher on the DC input side of things. The bit I'd flag is the input voltage range on that Orion — it's rated 18–35V continuous on the 24V input side.
@BevJackson64 your post cut off like the BMS did 🔋

@LindaClark90 classic SmartShunt calibration gremlin! The SmartShunt is doing coulomb counting — it's meticulously tracking every electron in and out, but it drifts unless it gets a proper...
