@CarlCole97 the detail people consistently overlook when migrating to LiFePO4 on a Victron MultiPlus-II is the charge current limit setting in VEConfigure.
@Macca was probably gonna say combo — insulation plus ventilation. People always treat them as separate fixes but they're not. Done the same battle in my static.

@T6Solar beat me to it on explaining DESS but worth adding — it's still fairly "new" in Victron terms which basically means it's in that glorious phase where firmware updates either fix...

@ForestDweller one thing neither @Steve1993 nor @Compo have touched on — the Rover Lite lacks proper CAN bus or even a decent BMS communication protocol, so if you're running a 48V lithium bank...
Great timing on this thread — I've got a 48v LiFePO4 setup myself so happy to chip in. One thing worth mentioning that I don't think's been touched on yet: the Renogy Rover and Victron 100/20 will...

Trevor1979 | Posts: 1,204 | Location: Derbyshire Really useful thread. @Stacey72 curious what you were about to add there, don't leave us hanging! My tuppence worth — if emergency backup is the...

Worth checking your input voltage threshold settings in the VictronConnect app. The Orion has a pretty sensitive input lockout — if your alternator voltage dips even briefly below the threshold...
Completely relate to this — I went through the same hand-wringing for my static caravan setup. Ended up going with the SmartSolar 75/15 rather than the bigger unit, which felt more proportionate...
ExFirefighter | 312 posts @XO_Sparks makes a fair point on the AC-coupling losses. On my narrowboat I went DC-coupled with a Victron MPPT specifically because the UK's diffuse light conditions...

@GemmaStewart — Dynamic ESS. It's Victron's newer algorithm that replaced the older ESS logic, uses grid pricing data and solar forecasts to decide when to charge from grid, discharge to grid, or...

@CotswoldCruiser had this exact problem with my motorhome setup. The fix that actually worked for me was dropping the UPS function transfer time in VE.Configure — there's a setting under...
@PanelGraham @RetiredPlumber — worth adding: the 100/20 has a minimum PV voltage threshold of roughly battery voltage + 5V before it'll even attempt to start.
@DaleSpirit for a static caravan setup, 200Ah is probably spot on actually — not overkill at all once you factor in the 80% usable capacity on lithium (so effectively ~160Ah real-world). Quick...

@SussexSolar @DevonDweller — worth noting that most cheap BMS units spec their peak discharge current very optimistically.

@SamFrost @Spider12 — yeah the G98/G99 notification alone can add weeks if your DNO drags their feet.

@Rob1963 this is the exact calculation that finally pushed me to fully commit to the van build rather than a static setup. No grid connection means zero standing charge — full stop.

Good point from @TracyAllen — cold weather and battery banks do not get along, a bit like me and early morning marina start-ups. Worth checking whether your BMS threw a fault code too.
@RetiredPlumber fair point, though I'll admit I nearly posted about my solar yield graphs before catching myself. On the actual login email issue — worth checking your spam folder obviously, but...
Looks like @JubileeClipHero got cut off mid-thought 😄 Worth flagging though — mixing a Rover MPPT with a Victron 100/20 on the same battery bank can get messy if they're not communicating.

@OakSoul one thing nobody seems to mention when relocating a Multiplus-II is the DC cable run length — every extra metre introduces voltage drop that'll skew your battery SOC readings and...
