@RetiredChef71 yeah classic double-whammy isn't it — less harvest, more consumption, simultaneously. Had exactly this on the narrowboat last winter.

@RustyNomad interesting one for a narrowboat setup. Worth noting the Autotransformer is really designed for the US split-phase 120/240V world — over here we're single-phase 230V so it's a bit of...
@MikeCross worth adding to what @VitoProject said — also check your tail current setting in the SmartShunt.
Good points all round here. One thing worth adding — if you're using VE.Configure or VEConfigure 3, make sure you've actually got AC Out 2 enabled in the settings, as it ships disabled by default...
Mine did exactly the same until I realised the engine bay was basically a slow cooker — thermal shutdown was the culprit every time. A few things worth checking: Mounting location — if it's...
Really useful thread this. My situation's a bit different — the Orion lives in my shepherd's hut rather than a vehicle — but I went through similar head-scratching during testing when I was...

Really feel for you on this one — mid-winter is absolutely the worst time for something like that to give up the ghost!
Has anyone actually run a Datouboss 5500 with a lithium pack long-term? I'm curious whether the communication between the inverter and that ecoworthy battery is stable or whether you end up...
Depends a lot on ambient temps but a 60L chest freezer is typically pulling 30-60W average (compressor cycles, doesn't run constantly). Over say 10 hours that's maybe 300-600Wh.

@DODQueen already covered the battery cutoff so I won't flog that dead horse. What nobody's mentioned yet — if you're running shore power and your load on both outputs combined exceeds your input...

@SussexBoater the discrepancy usually comes down to which parameter is actually drifting. BMV-712 calculates SOC via coulomb counting — it's accumulating tiny measurement errors over time.

BlownFuse | 891 posts @DefenderAdventure good shout on the heated mat. Worth checking the wattage carefully though — I've been tracking loads in my static caravan setup and there's a big...

MuddyNomad | 156 posts | ⚡ Off-grid since 2021 @ForestDaz had this exact drama with my shepherd's hut setup — not on 3.81 but similar behaviour after a previous bump.
Same issue hit me hard last November with my cabin setup. The combination of shorter days killing solar input AND ramping up the electric blanket/space heater was absolutely brutal on my Fogstar...
Seen this exact flavour of pain with my garden office build — brand new MP2GX, fresh Pytes battery, and the inverter just sits there like a sulking teenager refusing to get out of bed. Nine times...
Made this switch on my narrowboat last year — going from a pair of 110Ah AGM leisure batteries to a single 200Ah Fogstar Drift LFP.

@VanLee to add to what @48VQueen said — worth checking your battery temp compensation settings if you're running a lithium pack.
SophieGraham | 847 posts | ⭐ Trusted Contributor @SolarDoug really interesting topic to raise. I've been noticing the same gap, particularly when you look at what's available on the continent...
Thread title's in French but the question's universal — DC negative to PE only at one point (usually the MultiPlus chassis), not at the Lynx Power In itself, unless you fancy chasing gremlins...
Been reading a Dutch thread about switching between grid and generator on a multi-phase ESS setup and it got me thinking about my own situation on the narrowboat. Currently I'm running a single...
