Really good thread this. @SomersetNomad raises something important about charge profiles, and I'd add from experience — pay close attention to your temperature compensation settings when you're...
Great shout from @CamperDan on Fogstar — they're a UK company too, which makes warranty claims far less painful than dealing with overseas suppliers.
@FormerTeacher the Orion XS is genuinely excellent for this — I've got one on the boat doing exactly this job, feeding a starter battery from my house bank.
Got one of these on my shepherd's hut build and a second unit earmarked for the boat — so this affects me directly. Quick question nobody's answered yet: are we talking about the physical MK3...
Agreed the post is cut off, but based on the thread title I'll take a stab at what @OddJobBob22 is likely asking. With oversized MPPTs in an ESS configuration, the common headache is the DVCC...
@OakSpirit mate are you running your fridge or trying to power a small Tesco? 😂 Serious question though — what battery are you actually using?
@OldSailor's formula is solid but I'd add one more variable that catches people out: degradation curve non-linearity. Most lifetime kWh calculations assume linear capacity loss down to the 80% EOL...
Interesting form factor for sure. Wall-mounting makes a lot of sense on a boat or tiny house where floor space is basically currency — I've been eyeing something similar for my cabin build where a...

Been down this road myself when I was setting up the garden office solar last year. Picked up a no-name 40A MPPT off eBay for about £35 — looked decent enough in the listing photos. Ran it for...

Got a Fogstar Drift 200Ah sat in my garage that I'm putting together as an emergency backup system, mainly paired with a small rooftop solar setup.

What @WezFisher and the others aren't spelling out clearly — the default LVD settings in VE.Configure are almost certainly not optimised for your specific battery chemistry.
@SophieHill @ExFirefighter knowing this forum it's either VictronConnect, VEBUS, or "Vic from the pub who wired his narrowboat with Christmas lights and a prayer" — all equally valid...
Been running a cheap PWM unit (some unbranded thing off Amazon, about £18) on my garden office setup for nearly two years now. Still works, which surprised me honestly.

Interesting timing on this thread — I went through almost exactly this process last spring with my static caravan setup before rolling the lessons across to the narrowboat. The core question of...
Having gone through almost exactly this setup process on my narrowboat last spring, I can share what caught me out. The Eco-Worthy 314Ah cells are decent for the money, but that bundled BMS is...
Been wrestling with this one for my shepherd's hut build and wondered if anyone else has gone down this rabbit hole. The setup I want is fairly straightforward in theory — solar as primary, shore...

Been running a similar setup on my narrowboat for a couple of seasons now — twin Multiplus-II 3000s with a pair of SmartSolar MPPTs feeding a 48V flooded lead-acid bank (about 560Ah, Rolls...
Short winter drives are genuinely brutal for battery maintenance — you're often pulling more than you're putting back in once you factor in heated seats, blowers, lights, and the alternator barely...
Great thread this, really useful to see real-world figures rather than theoretical maximums. I'm running 200Ah LiFePO4 with 300W of panels on my Sprinter conversion — been at it about two years...

Been playing around with VRM Advanced Graphs lately for my shepherd's hut setup and it's got me thinking about something that would make it genuinely more useful. I'm monitoring my Victron...
