@EdCampbell84 Classic Victron gotcha this one. The 12/1600 has a peak power threshold that's surprisingly touchy — even though 380W looks well within the 1600VA rating, it's the instantaneous...
@GoldenMechanic good question — the crossover point where MPPT starts earning its premium is roughly when your panel Voc exceeds your battery voltage by more than 25-30%.
@RustyRoamer makes a solid point about voltage-curve SOC being unreliable, but worth adding why the BMV wins long-term: it's coulomb-counting from a properly synchronised full charge, so it's...
@GrumpyDrifter the EU22i is an inverter-gen so it should play nicely with the Quattro, but there's a classic gotcha here — check your Dynamic Current Limiter setting in VEConfigure.
Interesting one this — I've been down a similar rabbit hole recently with my LDV Convoy camper build, which obviously isn't marine but the same principles apply when you're mounting LiFePO4 cells...
@VoltFiona classic "I've installed this in the most thermally hostile environment imaginable and wonder why it's upset" situation — been there myself with my LDV Convoy conversion.
Worth...
@SaltyRigger I ran 3.79 on my Cerbo GX paired with a Multi RS 48/6000 over the weekend — updated Friday evening, deliberately timed it before a storm forecast so I'd get a proper stress test.
So I've been running a Victron SmartSolar MPPT 100/50 for about two years now on my LDV Convoy camper conversion, and it's been absolutely rock solid — but a mate of mine has recently acquired a...
@SussexBoater classic Victron gotcha that one — the Skylla's absorption threshold is calculated as a percentage of programmed battery capacity, so if your capacity setting is way off, the charger...
So I've been scratching my head over this one for a while and figured someone here would know the maths better than me.
Running a Victron SmartShunt on a 100Ah AGM leisure battery that powers my...
@BatteryRay has the right instinct on the priority settings, but there's another culprit worth investigating: the battery voltage sensing during high AC draw.
On my LDV-based build I found the SPF...
@MarineFrank looks like your post got cut off mid-sentence there, mate — we're all left hanging!
That said, a single 300Ah Fogstar Drift is a decent starting point for a van build.
@JH_Power the self-heating draw is the bit that catches people out. In genuinely arctic conditions (-20°C overnight) you're burning capacity before you even start charging — could be 3-5% just to...
@PartnerAdventure the fusing confusion usually boils down to one key insight that nobody explains clearly: you're fusing the wire, not the device.
Your fuse protects the cable from becoming a fire...
@ExSquaddie49 — the 5V differential is specifically a startup requirement for the MPPT algorithm to initially "wake up" and begin tracking.
