@FEE_Solar raises a good point about the curved roof issue on narrowboats — worth adding that you can sometimes get around this with tiltable aluminium mounting frames along the gunwales rather...

Got two 175W panels already wired to my Victron SmartSolar 100/20 on the motorhome roof. Found a cracking deal on a single 200W panel and wondering if it's worth chucking it in series with the...

Just wired up a 200Ah Fogstar Drift 12V to my Multiplus-II 12/3000 and trying to nail down the charge profile.

@LisaKelly66 is on the right track but didn't finish the thought, so I will. Your 100/30 is using its own internal voltage-based SOC estimation, which bears essentially no relationship to what the...

@RobHenderson I had almost identical behaviour on my boat last winter. Turned out my absorption time was set too short in VE.Configure — the MultiPlus was hitting the voltage threshold quickly on...

@NicolaTaylor72 I've had almost identical behaviour on my boat — worth also checking whether your battery capacity setting in VictronConnect is actually correct.
Really useful thread this. I've got a Victron MultiPlus setup which helps enormously here — it'll automatically switch to the generator input the moment it senses the batteries dropping below a...

@ForestDweller living this nightmare on my own boat — BMS said "nope" on a -3°C morning last January and left me with a very cold and very dark breakfast situation that no amount of...

Been running a Renogy 48V 3500W for about four months now in my converted horsebox up in Yorkshire. Honestly pretty solid so far — handles cloudy days better than I expected, which as we all know...

Last summer I finally ditched the old coolbox and fitted a Brass Monkey 50L compressor fridge in the van.

@MarineKaren is absolutely right about cable runs — I spent a weekend on my knees pulling 6mm² through a conduit I swore was accessible until it suddenly wasn't.
Good shout from @VivaroWanderer on the temperature angle, but worth adding that I've seen this same drop-out behaviour on a Daly Smart in a perfectly warm environment — turned out to be ground...

@FEE_Solar raises something really important there — curved roofs on narrowboats are a nightmare for standard rigid panels anyway, so the flexibility argument goes beyond just aesthetics.

Been running a 100/30 MPPT on my van build for about four months now — two 175W panels in series feeding a 200Ah lithium (a Fogstar Drift, since you're asking).

Running a Victron SmartSolar 100/30 with a 200Ah lithium (a Lion Energy UT 1300) on my narrowboat. During summer it was spot on — hit 100% around midday, held it, all made sense.

Really familiar with this one — my garden office setup went through exactly the same drama last January when we hit a cold snap. What sorted it for me was wrapping the battery bank in closed-cell...

Good point from @ExChippie94 about load changes — I'd also add that it's worth checking the physical mounting.
Ella in Batteries & BMS 7 months ago thumb_up 2
Something @MandyRoss touched on is worth digging into further — if your BMS is actively talking to the Victron via VE.Direct or Cerbo GX, it can override your manually set charge voltages...
