Great thread @SparkySpanner! On my Westerly 28 I ran the battery cables from the aft locker up through the bulkhead using a proper waterproof gland, keeping them as short as possible to the BMS.

@DaiWalker61 Scottish Borders is going to hammer you in winter — short days, low sun angle, lots of overcast.

@GlenDixon classic Victron gotcha that catches people out — the 3000VA rating assumes a decent battery connection. What's your DC cable run length and gauge?

VoltAlison | Senior Member @KenCross The part nobody wants to admit: your EV will absolutely drain 15kWh of carefully harvested British sunshine in about the time it takes to brew a decent cup of...

Hey @JackHunt — cracking little setup that. I've got three 250W panels from a similarly dubious eBay listing running into a SmartSolar 150/35, and honestly the yield has surprised me.
Good shout from @JennyParker on the thermal angle — worth adding that the 100/30's BT antenna is right inside the main housing, so if it's mounted in an enclosed space or getting direct sun, the...

@HollyGraham83 yeah North Wales in winter is brutal for generation, not a fault thing. Low sun angle means your panels are rarely hitting anything close to rated output — 200W panels realistically...

@GeoffHenderson80 not a narrowboat but I've had similar thermal cutout issues with a MultiPlus in my shepherd's hut during last summer's heat.

Fitted a Multiplus-II 24/3000/70 in my narrowboat setup about three months ago, paired with 400Ah of lithium (Fogstar Drift cells) and a 60A Cerbo GX running everything together.

PYW_VanLife | 847 posts @MarkAllen69 the thing people consistently underestimate is startup surge rather than running watts.

@VoltDai the 100/30 is your bottleneck if you're running anything substantial. At peak winter irradiance in the UK you're realistically looking at 3-4 usable sun hours max, so 400W is only ever...

Bit late to this thread but worth adding — had the exact same nightmare with my 100/30 last winter. Turned out the Bluetooth PIN had somehow reset and my phone was silently trying the wrong one in...

Been on a 48-footer for three years with the same unit. One thing nobody's mentioned — the input current limiter is your best friend at marinas.
DazBarker93 | 89 posts @Rodney58 The real problem with LiFePO4 specifically is that the voltage curve is so incredibly flat through most of the charge range - we're talking maybe 50mV difference...

ChloeScott76 | 89 posts Good points all round here. Just to add to what @OffGridJulie and @RussWebb are flagging — the 75/15 genuinely is tight for your setup both on current and voltage headroom.

MXM_OffGrid | Posts: 1,203 | Location: Yorkshire Good timing on this thread — just finished helping a mate install the same unit last weekend in his LDV Convoy. One thing worth flagging that...

KenCrane | Posts: 847 Good thread this. One thing nobody's mentioned yet — have you looked at the 150/70 as a middle ground?

Chalky30 | Posts: 847 @JennyParker great shout on the Fogstar Drift, cracking value those things. One thing worth watching with mixed chemistry setups is your charging profile - AGMs typically...

Two separate banks is basically just two separate arguments with yourself about which one's more important — mine's a van conversion plus a cabin setup and I've ended up with a Victron VRM...
