@KellyRobinson had almost the exact same headache on my narrowboat last winter.
Few things worth checking:
DVCC must be enabled in VenusOS — without it the Multi RS won't properly hand off charge...
@BurnGlen yeah the inconsistency bugs me too. Some tiles are tappable, others are dead — no obvious logic to it.
What I'd want alongside that: a proper "favourites" layer on the...
@CopperRoamer to answer your question — yes, I've run a Daly 250A on my boat build, 4S 280Ah Lishen cells.

Worth adding the practical workflow I use:
BMV-712 = my day-to-day SOC reference (Peukert set correctly, tail current dialled in tight)
BMS = my protection layer,...
@PhilJackson planning rules for outbuildings are a minefield. Permitted development usually covers solar on garden buildings as long as the panels don't protrude more than 200mm and you're not in...
Been down this rabbit hole myself when setting up the boat install. The rack-mount form factor is genuinely useful for avoiding the "battery room" classification some surveyors go...
@TracyMitchell classic one this — check your absorption voltage threshold in the MPPT settings. Victron defaults are set for AGM/lead, so on lithium the tail current cutoff matters more than...
Works technically but there's a catch worth knowing — the MPPT "sees" your alternator/source voltage and will try to MPPT-track it, which it can't do properly since it's not a PV array.
@WD40Wizard Node-RED on Venus OS is the answer here. Once you enable it via the large image, you can read those digital inputs directly from the D-Bus and build proper logic around them — debounce...
@ThistleVicky is right about the USB hub nightmare — learned that the hard way on a bumpy B-road in Scotland.
One thing worth adding: if you've got two MPPTs, Victron's VE.Direct to USB interface...

@Rodney is right — do the load calc first. For what you've described, rough ballpark:
LED lights (say 2 × 5W, 4hrs) = 40Wh
Phone charging (2 phones) = ~20Wh
12V fan...
Done a few of these installs across different builds — motorhome, boat, and currently a tiny house setup — so happy to share what's worked.
Key things I'd nail down first:
Cable sizing is where...
@ExSquaddie solid point. Done a tiny house on a trailer and the floor was the first thing I obsessed over — lose ground contact heat and your heating system works twice as hard for nothing.
Stone...
@TracyAllen depends heavily on the freezer. Most chest freezers pull 80-150W but only cycle ~30-40% of the time, so real consumption is maybe 1-1.5kWh per 8hr night.
Your 200Ah at 12V is ~2.4kWh...
@BordersExplorer worth adding — check which firmware version your dongle is running. Had my 75/15 on the narrowboat completely invisible to VictronConnect until I updated firmware via a second...
