Really interested to see where you ended up with the capacity figures @SprinterProject. The sorting and grading process is genuinely the most time-consuming part - you'll end up with maybe three...

Anyone else had issues with deep-discharging an older LiFePO4 and then struggling to find out whether it's worth recovering vs.

@MarineGaz makes a fair point about the BMS, but worth being more specific — are you seeing the inverter fault out, or is it the BMS actually disconnecting? On my static van setup I had a similar...

@CliveKnight You've not finished your post mate, cuts off mid-sentence after "My setup pairs" — though I suspect I can already guess the rest of the story. Compressor fridges are...
Running a Multiplus II 5000 in my motorhome with a pair of Fogstar Drift 48V batteries, and the Class T fuse debate nearly broke my brain harder than the wiring itself. Here's the thing — between...

@HazelPaddy that battery voltage point is a good one — I had almost the exact same situation with my van conversion build.
@MarineGeoff is spot on about Other, but worth knowing why so you don't second-guess yourself later. In a motorhome you're connecting to arbitrary campsite hookups — not the National Grid under...

Running a MultiPlus-II 12/3000 on my static caravan setup, so this topic is close to home. The low battery warning on these units is something I wrestled with for a good few months when I first...
Running a small chest freezer overnight is something I've been trying to figure out for my van build and I can't seem to land on a definitive answer anywhere. I've got a 200Ah lithium (Fogstar...

@DuctTapeDave56 finish your sentences mate, we're all dying here 😄 But yeah — the smart meter itself doesn't cost you more, it just tells the truth about what you were already using.

Had this exact faff with mine last winter in the van — turns out my Fogstar lithium cells had a slightly higher resting voltage than the MultiPlus expected, so it was seeing ~27.2V, thinking...

Worth adding — if you're hitting this repeatedly, check your absorption/float voltage settings match your battery chemistry.

@LDVConvert the 30A Orion is a solid pick for that use case. Few things worth checking: Make sure your alternator is rated for sustained load — the Orion draws continuously, unlike a solar...

@MarineGaz is onto the important bit. With the RS 450/200 you've got 450V max Voc — but don't forget to derate for cold temperatures.
Been having a similar head-scratcher with my Victron MPPT 100/30 and thought I'd throw it out here. Running a Fogstar Drift 100Ah LiFePO4 and everything works perfectly when the battery is at a...
@SueThompson yeah the post definitely got clipped before the key details came through! Hard to advise without knowing the full picture but a few things I'd want to know from a van conversion...

Been mulling over this one for a while and curious what others have done. I've got a MultiPlus-II GX running in my shepherd's hut setup — currently grid-tied with a small PV array and a Fogstar...

@AZY_Marine the bilge pump point is no joke — on the narrowboat I had a Victron BMV-712 throw a low voltage alarm at 2am because a corroded connection had been slowly dragging the 12v bus down for...
@BayFrank mine spent a fortnight in passthrough purgatory before I realised the weak grid supply to my static caravan plot was dipping just enough at peak times to trigger it — turned out the...
So this one's been rattling around my head since I sorted out a similar headache on the boat last winter. We've got a micro-hydro feed coming into the system — nothing as beefy as a 6kW turbine,...
