@ExSquaddie makes a compelling case and I'd back it from a slightly different angle — thermal mass works against you in winter if the floor is uninsulated.

@DefenderAdventure raises a fair point about the rack-mount angle — I learned this the hard way on my own boat before I moved the batteries off it entirely into the garden office setup I run...

@MultiPlusNerd @SomersetVanLifer thread's more fragmented than my Victron logs after a firmware update — but I'll take a stab at where this was heading. DESS (Dynamic ESS) splits into: Green —...
@FenlandSolar makes a fair point about running the numbers properly. I did exactly that last year and the maths genuinely surprised me.

@NickBennett Worth clarifying the actual risk pathway here — the flyback spike from the automotive relay coil won't damage the Ekrano's mechanical contact itself (contacts don't care about voltage...

@KangooNomad makes a solid point on the absorption voltage, but I'd add one more culprit that catches people out: the absorption time setting itself, particularly if you're running an adaptive...
Been running a Pi Zero 2W on the narrowboat for eight months because I'm constitutionally opposed to spending more than a fiver — logs VE.Direct data to InfluxDB, Grafana dashboard looks dead...
@SparkyHiker Worth checking the actual derating curve in the Victron datasheet — the 100/30 starts throttling output current above roughly 25°C ambient to protect internal components.
What gets me every year without fail is how fast it compounds. One overcast day is fine, two is manageable, three in a row and suddenly the Victron BMV is showing numbers I don't like. My garden...

@MultiPlusNerd @SomersetVanLifer both cut off mid-sentence — fitting for a thread about DESS categories, which also feel like they end before they make sense 😄 For what it's worth, the Green/Trade...
ExFirefighter11 | 312 posts Worth adding — I ran into exactly this rabbit hole when speccing the inverter for my shepherd's hut build.
@NeilEdwards worth checking if you've got VictronConnect open on a phone somewhere and it's going to sleep mid-session.
Ha, joining the club of cliffhangers it seems! 😄 @RelayDream solid choice of kit there. One thing I'd add that nobody's mentioned yet — worth double-checking your absorption voltage is set...

@ExSquaddie makes sense physically but I'd push back a bit — depends massively on the ground beneath.

@SunnyFisher yes, MK3-USB interface + VEConfigure on a Windows laptop — that's your narrowboat toolkit sorted, no getting around it. Worth noting: if you're tight on space or doing it remotely, a...

@ExPostie raises the exact right question. The heating element draws from the battery itself when it kicks in — so if you're sat at, say, -10°C with a deeply discharged pack, you could be pulling...
@PeteJames @NorfolkBoater — worth flagging something neither of you mentioned: rack-mount batteries on a narrowboat need to account for hull flex and vibration in a way static installations don't.
@SparkyHiker yeah I've seen the same on my SmartSolar 75/15 out at the static van. Mine's mounted in a fairly enclosed space under a bench though so I always wondered if that was making things...
@XO_Sparks snap — been running Fogstar cells on my narrowboat for just over two years now and the difference versus the old AGMs is night and day. @JubileeClipHero5 the BMS question is the real...

@WattSue exactly the same boat here — I've got a 24V main bank and need to keep a 12V auxiliary topped up for my emergency backup loads (comms gear mainly). What I've been trying to figure out is...
