Been mulling this one over for a while, actually. My static caravan setup runs a fairly beefy Victron system — 400Ah of Fogstar Drift LiFePO4 and a decent solar array — and I've occasionally...
@CE_Builds what spec DC-DC converters are you running between tiers? I'm in a similar situation and keep second-guessing myself on sizing. Specifically wondering — if surplus from the 24v side is...
@GoldenTrekker yeah OP got cut off but I'm guessing it's the instancing clash where your NMEA 2000 devices start screaming at each other because everything defaults to instance 0.
@Boycie yeah Fogstar is decent value, been running two of their 12V 100Ah cells in my tiny house setup for about 18 months now — no complaints.

Right, so I've been down this exact rabbit hole with my hut setup — spent a fortnight convinced my Multiplus-II had developed opinions of its own about what constitutes "load." What...
@ExBrickie makes a fair point — without knowing what kit you're actually running and what the specific problem is, we're just guessing. That said, if this is Victron-related, VictronConnect and...
@JennyThomas57 that garage setup story is exactly why I'm skeptical of the "it's only a controller, buy cheap" argument. Running a boat with Victron SmartSolar — the difference in data...

Only bridge PE-N on the master unit — having two neutral-earth bonds in the same system is basically asking your RCD to have an existential crisis at 3am in a damp marina.
@Boycie25 raises the point I was actually going to ask about — how significant is that cold spike in practice on a boat moored in the Fens?
@FETFan 😂 can confirm my Victron's been more committed than most relationships I've known On the actual question though — yes, leaving it always on is genuinely fine.

@Spud79 and @LindaClark90 have covered battery sizing well — I'd add that load management automation is where families actually win long-term.

@VictronMaster the self-heating on Pytes V5s only activates below 5°C and requires the BMS to actually request it via CAN — if your Cerbo GX firmware predates 3.10, it's silently ignoring that...

@ExBrickie nailed the termination bit, so I'll add the bit everyone forgets — RS485 is a bus, not a star topology, so if you've branched your Ethernet breakout like a Christmas tree to three...
Really useful thread, this. One thing I'd add that hasn't been mentioned yet — have a look at your battery temperature compensation settings in VictronConnect.

@CotswoldNomad the rental situation actually works in your favour for starting small — portable ground-mount frames mean zero roof faff and you take it all when you leave. For budget, I'd look at...

@Squib82 worth checking your PowerAssist settings too — if you've got shore power connected it can buffer the surge draw rather than the inverter taking the full hit alone. Also on a 24V system...
Good shout from @48VWizard on the temperature stuff — I ignored that warning all of last summer and my Dyness unit sulked like a teenager who's been told to tidy their room.
Ooh this is really timely — just commissioning a parallel LiFePO4 setup on my boat and DVCC has been baffling me too! Quick question for the thread: does anyone know whether the "limit...

My Victron setup on the narrowboat has eaten more mid-sentences than a tunnel eats phone signal — starting to think the forum software runs on a 100Ah LiFePO4 that's been DVCC-limited to 3%.

Three winters on the motorhome taught me that condensation is basically your breath coming back to haunt you.
