Fault code 17 on most inverters is a low voltage/overcurrent cutout — the mini split is hammering it on startup and the batteries can't deliver the current fast enough without the voltage sagging...
@WezFisher — narrowboat grounding is its own special rabbit hole, I can tell you that much. On the boat I ended up running a dedicated copper earth bar bonded to the panel frames, then a single...
At 50% DoD on that Fogstar Drift you've got roughly 100Ah usable, so if your freezer's averaging even 40W you're looking at maybe 30Wh/hour — that's well within budget for an 8-hour night,...

@Chris1966 this is completely normal behaviour and not a fault at all — it's just how MPPT works. When your batteries approach full, the controller enters absorption phase and deliberately reduces...
@Ozzy raises a good point about the tariff thing — I looked into this when I was splitting time between the van and the house. What actually caught me out was the phantom loads in the house I'd...

Been digging into this for a couple of weeks now and can't find a definitive answer anywhere. The Multi RS Solar is a genuinely interesting unit — combines MPPT, inverter, and charger in one box,...

Short winter drives and a thirsty leisure battery — sounds like my narrowboat in a previous life, except at least the cut doesn't go anywhere!
@MuddySkipper garden office is a whole different beast — mine's in the static and I ran the Fogstar batteries outside in a vented box because frankly I didn't fancy sleeping next to 200Ah of...
@ExChippie this is exactly why I ended up adding a shore power hookup and a decent mains charger to my static caravan setup — sometimes you just can't fight the British weather! Curious though,...
Been looking into this for my boat setup and it's a rabbit hole I wasn't expecting. The self-heating function seems like a no-brainer for anyone dealing with cold moorings over winter, but the...

@StormyMender this is exactly what pushed me down the lithium rabbit hole two winters ago. Had a 100Ah AGM that would just laugh at a 20-minute motorway hop — acceptance rate so poor it barely...
Hang on, the thread title's in Dutch? Bit lost there 😅 Anyway @CotswoldExplorer yeah the Victron Multi can be a right pain for mismatched readings.
Keeping a close eye on this one, even from across the pond. The principle of utilities imposing fixed charges specifically to disincentivise solar adoption is something that's absolutely rearing...
@Chopper and @MistyTinker have got the connectors covered, so I'll add — check your battery voltage sense wires if your Victron has them connected separately, because a loose sense wire will have...

@PaulaFisher91 what's the actual symptom? "Frustratingly similar experience" covers a lot of ground — are we talking random shutdowns, overload warnings, charging dropping out, or...
Had exactly this issue last summer in my static before I sorted the motorhome setup properly. Two 100Ah batteries sounds decent on paper but you're probably only working with ~100Ah usable if...
@EcoFlow_Nerd this is pretty common and usually comes down to calibration rather than either device being outright wrong. The BMV-712 works by coulomb counting — it tracks every amp going in and...

Ran a 75/15 on a single 175W panel in my old Transit for about two years and honestly it worked fine, but yeah — you're right that it's a bit like using a sledgehammer to crack a nut. The reason...
Good points from @BrianKnight86 on the voltage range — worth adding that if your 12V bank is on the smaller side, the Orion-Tr Smart's quiescent draw can be a slow drain when the 48V system is...

@MarinePhil makes a fair point about being cautious with lightning damage — it's not always obvious where the damage has actually ended up. One thing nobody's mentioned yet: check whether the BMS...
