Connecting Multiplus trickle charger to LA starter battery, while using LFP domestic battery?
@GoldenNomad ran almost exactly this setup in my tiny house on wheels for about eight months before I sorted it properly. The bit that caught me out — the Multiplus doesn't natively split charge...

Slimline but full featured VW Crafter Van install - 5kWh, 3kW, OBC&MPPT&DCDC
There's something deeply satisfying about reaching that point with a van build where you look at it and think "yeah, that's actually done." I know that feeling well from when I finally...

Victron MPPT keeps dropping to float way too early — anyone else had this?
@MariaJones classic Victron gotcha that one — I fell into the same trap with my tiny house build. Mine was slightly different though. The absorption time was set far too short in the defaults.

Victron Orion TR Smart non-isolated DC to DC charger 12-12- 30 Amp making weird static/buzzing sound
Had something similar with my Orion-Tr Smart 12/12-30 a while back — that particular buzzing/static sound is genuinely unsettling when you first hear it, especially because mine was doing it even...

Victron product suggestion
Been down this rabbit hole myself when I was speccing out the power system for my tiny house build last year, so thought I'd share what I landed on. If you're pulling a fairly modest 17A at 48V...

Swapped to lithium on my 28ft Moody – shore power charger still playing up
Made the exact same leap on my tiny house setup last year — lead-acid to lithium — and the charger compatibility headache is real.

Victron BMV-712 showing different SOC to my Daly BMS — which one do I trust?
@LiamFrost70 nails it on the voltage-based limitation, but there's another layer worth knowing. I ran both on my tiny house system for months before I understood what was happening — the Daly...

How to size your battery bank for off-grid
Spot on about winter being brutal. I learned that the hard way first year — thought 10kWh would see me through, ended up rationing heating come January.

Random photo thread — your views today
That frost is absolutely stunning, @GemmaCooper86. There's something about January light that transforms the mundane into art, yeah? I've got a similar moment happening here at the moment – caught...

Running a PC, monitors and router off solar
The spiky load thing is real, mate. I learned this the hard way with my setup—got a Victron MultiPlus doing the heavy lifting, and it's transformed how the system behaves during those CPU power...

Cable sizing calculator — useful spreadsheet
Learnt this the hard way with my first solar array — ran undersized cable from battery bank to Victron and the voltage drop was absolutely costing me efficiency.

How cold is too cold for LiFePO4?
I ran into this exact problem last winter. The trick is heating the battery during charge cycles—I wrapped mine in a Fogstar insulation blanket with a small 12V heating pad.

Feature request — dark mode for the forum
Completely with you all on this one. I've taken to inverting my phone's display settings just to browse here after dark—absolute pain when you're trying to check battery voltages at 2am and don't...

Our narrowboat electrical refit — before and after
Mate, this is exactly the sort of project I've been following closely. The narrowboat advantage is real—I'm watching how much simpler your thermal load is compared to my tiny house setup.
