DodgyGrafter | 847 posts @Rodney58 One thing I'd add to what's already been said - temperature throws those cheap Daly SOC readings right off.

Woke up at 2am absolutely freezing — my Fogstar Drift 100Ah had shut itself off. Temps dropped to around 3°C inside the hut overnight and I'm guessing the low-temp protection kicked in.

Currently running four 110Ah AGM batteries (Numax) wired in parallel giving me 440Ah usable at roughly 50%, so about 220Ah in practice. Been doing this for three years on the boat and it's...
MrBodge | 📍 Array Worth adding: flat panels in winter suffer badly from the low sun angle but the Fens compound this with their notorious haar and freezing fog sitting for days at a time.

Hey @LazyFisher — worth looking at your battery monitor settings and specifically whether your MultiPlus knows it's dealing with lithium.

FellKev | 412 posts @ExJoiner6 My static in the Lakes had this exact drama two winters back. Frost-bright mornings are brutal — panels pumping out near peak Voc before the battery's had a chance...

Aye, it's been a nightmare hasn't it. I managed to snag a set back in March but I reckon I got lucky with the timing.

Has anyone found a practical workaround for keeping the battery warm enough to prevent the BMS tripping in the first place, rather than just waiting for it to recover?

Right, so I've finally convinced myself to sort out a proper backup system for the static. We're up in the Scottish Borders and the grid here can be properly unreliable in winter — last February...

@GlenDixon worth noting the charging side too — AGMs want a proper absorption stage that eats time, whereas LiFePO4 just... fills up and stops.

RetiredNurse58 | Posts: 847 @RhysLee78 This took me an embarrassingly long time to sort on my motorhome.

Great write-up @MickDavies, looking forward to reading the full lessons learned! One thing I'd add that caught me out on my own LiFePO4 install — make sure your alternator charging setup has a...

I've been running a Victron SmartSolar 100/30 with two 200W panels on the roof of my narrowboat since last spring and it's been brilliant all summer.
@SteveBurns yes, had exactly this on my boat setup. Pairing a Victron SmartSolar 75/15 via Bluetooth and it would just vanish mid-session, sometimes after 30 seconds, sometimes a few minutes...

@SimonJohnson67 the narrowboat use case is brilliant for this kind of setup - you can add GPS nodes into your Node-RED flows and log position alongside your battery state, which is genuinely...

Great points already from @Slim13 and @Tommo10. One thing I'd add @LakelandSolar - worth double-checking whether your split-charge relay is a voltage-sensing type or a proper VSR (voltage...

Hey @RogerHobbs, I had exactly the same issue running a van setup through a Scottish winter last year — brutal!

@BatteryWez worth thinking about what your worst case day actually looks like rather than the average.

@MarineClare two Drift 100Ahs freed up so much weight in my van I accidentally became a better driver — the handling improved or my ego did, genuinely can't tell which.
@XJ_Solar the curved roof edge issue is genuinely underappreciated — most mounting rail guides assume a dead-flat surface.
