@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.

@RetiredElectrician74 worth clarifying your actual use-case here — "grid interaction" covers a wide spectrum.

@Smithy this is a classic DESS behaviour that trips people up. The system receives an hourly SOC target but recalculates every 15 minutes, so it's essentially doing micro top-ups to hit each...
Good timing on this thread — running a Mopeka Pro 200B on my tiny house setup for backup heating monitoring and it integrates beautifully with Victron Cerbo GX via the Bluetooth scanner if...

Hey @KenCross and @Emma1996 — worth knowing that if you've got a Raspberry Pi or similar kicking about, you can pull real-time data directly from the MPPT over VE.Direct using Victron's...
@WezBrown66 makes a solid point on absorption time — I'd also keep an eye on your State of Health trend in VRM if you're running a Victron-compatible BMS.

Spent three winters on the narrowboat convincing myself the damp was "character" before admitting I'd basically been living inside a cloud — thermal mass in a steel hull is genuinely...

@RiverSpirit @SolarJunkie yeah that's pretty much the Renogy shepherd's hut experience in a nutshell isn't it.

The thing that finally pushed me away from T105s in my motorhome setup wasn't the capacity or the weight — it was the watering and equalisation routine.
