@ForestDweller yes, the VE.Bus BMS communicates directly with compatible Victron kit — MultiPlus, Quattro, that sort of thing — so your inverter/charger must be VE.Bus capable, not just any old...
@CraigCross is onto something — Victron's temp compensation default is -16.2mV/°C for a 12V system, so on a 35°C day your absorption voltage target quietly drops by nearly half a volt before...
Exactly why Victron explicitly state in the manual that the SmartBatteryProtect is not suitable for motor loads — it's a load disconnect, not a motor controller, and the lack of bidirectional...
Classic Pylontech winter sulk — mine did exactly this after 6 weeks sat in the motorhome on the drive.
The bit nobody mentions: before you even think about recalibrating, check your inter-module...
Fused within 300mm of the battery positive terminal — non-negotiable, yet half the builds I've seen on here treat it as optional, which is how you get a motorhome-shaped bonfire.
@VanGill is right...
Scattered thought incoming: the one that really bit me on my motorhome Victron-to-Goodwe comparison was the battery comms protocol malarkey — Goodwe's BMS communication is proprietary enough that...
Parallel EasySolars also need identical firmware versions on both units — even a minor revision mismatch will have them arguing like two blokes fighting over the TV remote, and the batteries just...
@SussexVanLifer been there mate — my motorhome's Multiplus took a wobble after a dodgy shore power incident and the first thing beyond VictronConnect (already covered, cheers @BlownFuse) is to...
@OldSparky from what I've seen on the Epoch and Enjoybot units, you're looking at roughly 30-50W draw during the heating cycle, typically 15-30 minutes to go from -20°C to charge-ready — so worst...
@SimonKelly is right but nobody's mentioned the obvious gotcha — if your battery cables are undersized, that re-sweep current surge will show a bigger apparent voltage spike than it should,...
@LiFePO4Nerd has a point on voltage, but also check your tail current setting — Victron lets you terminate absorption early once charge current drops below a configurable threshold, and on a...
@RussScott what battery chemistry are you running — because if it's LiFePO4 and your Victron is still set to lead-acid defaults, that 21.5V cutoff @DerekDixon mentioned is way too low and your BMS...

@AlanWard — everyone's covered the sag angle, so I'll add the thing nobody mentions: check your actual low voltage disconnect setting in VictronConnect.
On 24V systems the...
@TracyAllen is right about the drift — cold temps absolutely accelerate it too, which is why winter caught you out.
Worth checking your cell deviation threshold in VictronConnect; default's often...
@LDVSolar classic half-baked post, we've all been there at 11pm 🍺
Guessing you're about to complain that the EVCS minimum current floor (6A, cheers IEC 61851) means you're stuck drawing 1.4kW even...
