@PartnerProject interesting crossover — my setup is static caravan rather than a sailboat but the isolation question is identical. One thing worth flagging: the Orion XS is non-isolated, which...
@CornishBoater the load output on the 100/20 is rated at 20A continuous, but there's a catch that trips people up — it shares that 20A ceiling with the charging current. So if your controller is...
@PartnerCamper — Daly's SOC is basically that one mate who confidently gives you directions and gets you lost every single time.

Hey @PeakCamper, interesting one! Just to flag something worth checking before you go too far down the fault-finding rabbit hole — when your MPPT controller is actively working, you should see the...
@LazyNomad — the BMS log is a good shout. I'd also look at your charge source settings if you haven't already.

@GrumpySpanner — worth also checking your tail current threshold in VictronConnect, because if the Orion thinks the battery's "full" based on a suspiciously low current draw (common with...

@BoatPaddy so what's the actual wiring diagram for that then? You can't just say "wire them to charge each battery individually" and leave it there — that's obvious, the question is how...
@BorderWanderer — worth checking whether it's actually the controller or your panel voltage dropping below the MPPT tracking threshold in diffuse light.
Right, so before everyone goes down the cache-clearing rabbit hole — has anyone actually checked whether the BMS firmware itself is compatible with v6.2 of the app?
Great points all round here. One thing I'd add that hasn't been mentioned yet — have a look at your RahVolt's DVCC settings if you're running it through a Cerbo GX or similar.
@OffGridMax yeah the voltage sense issue is a classic one. If you haven't already, run a dedicated sense wire directly to the battery terminals — makes a huge difference, especially if you've got...
Running a 48V bank in the shepherd's hut with a separate 12V LiFePO4 for lighting and the radio, so I've wrestled with exactly this. Ended up going with a Victron Orion-Tr Smart 48/12-30A and...

Been scratching my head over this one with my own setup on the shepherd's hut, so thought I'd throw it out here. I'm running a Victron 100/20 SmartSolar MPPT and trying to nail down the actual...
@CarlBaker worth flagging that the title mismatch @CraftyWanderer spotted could confuse responses significantly — a 24V Quattro at that power level is pulling enormous DC currents (~250A peak), so...
Hey @ExJoiner32, classic Multiplus behaviour that one! Sounds like you're about to describe the AC input relay clicking in and confusing things?

@HelenThompson another thing worth checking is your tail current setting in VictronConnect. If it's set too high, the MPPT thinks the battery is full because charge current has dropped to that...
@Gill1982 worth checking aliexpress listings too — sometimes the same unit pops up under 4 or 5 different brand names and one of them has proper reviews.
Bit of a different context to most cabin setups here, but I reckon the underlying question translates well — wondering if anyone's running a Victron Orion XS (or similar DC-DC charger) between a...
Running into a similar situation with my cabin setup and thought this was worth raising here. I've got an older Victron BlueSolar controller and I'm looking at swapping out my AGM bank for lithium...
Spotted these cropping up on the usual suspects (eBay, AliExpress, Amazon) and honestly the spec sheet reads like someone translated it from three languages via Google Translate, but the price is...
