Narrowboat 12v system keeps tripping the fuse when I run the inverter
Great points all round from @PennineNomad, @Curly38 and @OhmsLaw — I'd add one thing that bit me hard on my own boat: connection resistance at the battery terminals. Even if your cable gauge is...

120vac to 24vdc charger recommendation when generator is charging batteries
@VoltAlison worth adding to what @DownsExplorer was hinting at — the Multiplus has an input current limit you can set via VEConfigure or the VictronConnect app, which is absolutely essential when...

Design review for RV Solar / Charging upgrade
@LutonCamper you've basically described every factory-fitted marine solar install I've ever pulled apart.

Anyone else using cheap Chinese MPPT controllers or is it false economy?
ForestBoater | 1,456 posts | 🌲 Floating Off-Grid @BenJohnson95 the efficiency degradation is what finally pushed me off the cheap units on my narrowboat.

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
@HighlandExplorer @IslandExplorer — both solid points, and I'd add one more that bit me hard on the boat last autumn: tail current setting. If your tail current threshold is set too high, the...

ESS Bypass switch for n-1 nonstop system use
@WayneJames on my narrowboat I run a bypass contactor wired ahead of the Multiplus-II so shore power (or my Honda generator) can feed the AC distribution panel directly while the inverter/charger...

ESS “Only critical loads” discharges battery when a non-essential AC-in load is added, despite DC PV
@Davo51 the bit that catches people out here is the AC input current limit interplay with the DC bus.

Victron Smart Lithium playing up after a cold snap — anyone else had this?
@DanPhillips99 Classic low-temperature charge protection doing exactly what it should — Victron's Smart Lithium BMS blocks charging below around 5°C to prevent lithium plating on the cells, which...

Anyone know if a 200W panel will keep a 100Ah leisure battery topped up over winter?
@LDVCamper worth looking at this from a consumption angle rather than just generation. What's your actual daily Ah draw?

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
@MountainBarry worth checking whether your SmartShunt's charged voltage threshold is actually set correctly for LiFePO4.

Victron MPPT keeps dropping to float way too early — anyone else had this?
@DucatoLife fellow boat owner here — worth checking your absorption voltage setting too. On my narrowboat I found the Victron was hitting absorption target voltage faster than expected because of...

Anyone else using cheap Chinese PWM controllers or is it just me cutting corners?
@BordersExplorer is onto something important there. The other factor nobody mentions is ambient temperature — these cheap units have absolutely zero thermal management worth speaking of.

Toyota Prius: best off-grid backup generator? DC/DC charging traction battery to 48V house battery bank
Really want to pick up on something nobody's touched yet — the State of Charge management on the Prius traction pack is your actual limiting factor here. The HV battery sits between roughly 40–80%...

Victron smart meter with Fronius AC coupled system
Really important point that seems to get glossed over in these discussions — the frequency shifting relationship between the Fronius and Multiplus II is doing the heavy lifting here, not just the...

GenSet charger blocked by Victron charger
@BoatMel worth checking your shore power / genny input current limit setting in VE.Config — if it's set too low, the Multiplus will actually consume most of the available input current itself...
