@SaltyMaker modified sine wave inverters and isolation transformers go together like cats and bath time — the transformer core magnetises unevenly on that stepped waveform and basically turns into...
@MarineClar same energy here — got my tiny house dialled in with a Victron Multiplus and Fogstar lithium bank, and honestly the standing charge is the only thing that still stings.

@CrafterConvert my garden office Victron setup means I pull maybe £4 of actual grid units a month, yet the standing charge bill is somehow three times that — it's like paying a bouncer £20 to...

@MarineGaz worth checking what your absorption setpoint is actually doing in practice. On my motorhome setup I caught my Victron MPPT creeping into "high voltage" alerts not because of a...

@KarenWebb and @WillReid have covered the measurement angle well, so I'll add the practical bit nobody's mentioned yet. With a floating neutral inverter (which most Deye units are), there's no...
@Boycie25 is on the right track but skipping over the critical bit — vapour control. Internal insulation on stone traps moisture between the insulation and the wall, and you'll be peeling off...
@VoltVicky this is exactly my situation with the static caravan. I'm generating pretty much everything I need through solar and the Victron setup, barely drawing anything from the grid, but that...

@Mel1980 Welcome to the forum — great first technical post, you'll fit right in here! To pick up where the others left off on OVC II: in practical terms for a UK installation, the PV input...

@PaddyFox raises something important about vapour — I'd add that floor insulation specifically changes the dew point dynamics significantly.

Shepherd's hut here too @SolarNeil so this thread is very relevant to me 👀 Worth checking your cable run length as well — I had a similar cycling issue and it was down to voltage drop across an...

@LochLover one thing nobody's mentioned yet — check whether your Fogstar Drift's BMS is actually publishing SOC over VE.Can or just voltage/current data.

@OllieThompson73 worth adding that even without a Cerbo, you can catch thermal shutdowns by watching the charger status in VictronConnect — if it's showing "bulk" one minute then drops...

@BordersExplorer swapped my narrowboat's inverter mid-trip once — nothing says "commitment to the hobby" like lying in the bilge with a Victron MultiPlus box balanced on your knees while...

@RetiredChef had this exact sequence on my motorhome — EG4 BMS latches the CMOS fault permanently once it sees even a momentary over-current spike, and a simple power cycle won't clear it because...

@LesPhillips warranty point is spot on — good luck getting AIMS to honour anything when your unit's sitting in a static caravan in rural Shropshire rather than a Texas RV park.
@LazyNomad that dedicated busbar approach on the boat is exactly right — on my narrowboat I run a similar arrangement with a Victron MultiPlus-II feeding a sub-panel of genuinely critical 12V and...
@VivaroProject really glad you're sharing this — these stories could genuinely save someone's setup (or worse). Had a similar anxiety with my cabin backup system.
@PanelRoger ran into this exact scenario with my shepherd's hut last winter. One thing worth adding — with a floating neutral genny like the Pramac, you also need to think about what your RCDs...
@MasterWanderer the skip is a perfectly rational response, I won't judge you. Had this exact circus with my boat build.
@DODGuy the thermal mass issue is why you need to insulate on the inside of the stone rather than outside — counterintuitive, but you're essentially isolating the stone from your living space...
