Hey @KangooBuild, interesting project! Just to add to what @EmmaEdwards82 and @RetiredPlumber were getting at — have you looked at defining a custom charge profile via VictronConnect?

@PeakExplorer good point on the maths — I run a similar setup on the boat and learned the hard way that 12V starts to feel limiting once you want to run anything with a serious startup surge.

Taffy42 | Posts: 561 @OakTel My narrowboat JK did the same until I realised the protection voltage and the alarm voltage were set independently — worth double-checking you've actually saved the...

@Gazza99 one thing I'd add to what @KeithMartin is hinting at — you'll want a dedicated dump load controller for the turbine side, completely separate from your MPPT.

Currently speccing out the battery bank for my Transit conversion and I'm torn between two options. The Fogstar Drift 100Ah is sitting at roughly £279, whereas the Pylontech US2000 (105Ah) is...

MariaJones | 234 posts | Solar, Static Caravan & Narrowboat @PanelGraham 15-20mV on a narrowboat is practically begging you to check your busbar connections — mine looked fine until I actually...

BerlingoConvert replied: @GrahamCole What BMS are you running on those EVE cells? On my narrowboat I had a JK BMS that was tripping the whole bank offline when temps dropped — looked exactly like...

BirchLover | Posts: 203 @T5Wanderer is right about the dedicated isolator — worth getting a proper rotary switch rather than relying on your BMS disconnect alone.

BoxerLife | 1,203 posts @Wendy1967 To add to what @EwanMorris76 is saying - worth checking whether your Fogstar has a low-temp cutoff threshold you can actually monitor via the app.

@VanHolly yeah I did wonder about cable losses but I ran the numbers — it's a fairly short run, 6mm² twin core, maybe 4 metres.

RussGreen | 312 posts | Array My van conversion basically is the OH NO box — 200Ah Fogstar, Victron SmartSolar, and a folding panel that lives under the bed.

@WonkyHermit absolutely nails it there 😄 The kettle is the silent destroyer of off-grid dreams. I'd add that after 18 months you're probably due a proper audit of your actual consumption patterns.

@KMV_Marine ran mine under the gunwale on the narrowboat — 70mm² all the way, properly sleeved through every bulkhead penetration with grommets that won't turn into cheese graters on your cables...

@Turbo19 classic cold-temperature behaviour from LiFePO4 — the cells' internal resistance rises sharply below about 5°C, causing the BMS to see voltage sag under load and trigger low-cell-voltage...

@MarkAllen69 your message got cut off — "I'm seeing s..." seeing what exactly? That said, worth flagging a couple of things with that setup whilst you finish your thought: Two 200W...
HazelPaddy | 412 posts Worth checking where exactly your multimeter probes are touching versus where the Victron's voltage sense point is.

@Shaun1970 the Orion-Tr Smart has input current limiting in the app settings — if you haven't dialled that down from the default, you're essentially asking your alternator to sprint a marathon...

@TransitProject similar story with my shepherd's hut build, except I went the static route rather than a van. What sold me on B2B was watching the voltage logs on my Victron BMV — the VSR was...

Picked up a Victron BMV-712 last autumn after my old £15 eBay shunt monitor started giving me completely daft readings over winter — talking 40–50% state of charge swings within minutes of putting...

@VitoProject worth checking your AC input current limit in VE.Configure too — if it's set low (say 16A) and PowerAssist kicks in late, there's a brief moment where the inverter is carrying the...
