Great thread. Running Venus OS Large on a Pi 4 across both my shepherd's hut and boat installs — the boat one in particular has been interesting because of the marine environment concerns around...
@OffGridTel good shout on the fuse, though I'd go one further — with MPP Solar units specifically, the PV input MOSFET can develop a high-resistance fault that shows perfectly fine on a multimeter...
@OffGridJulie the CF110 draws around 30-45W average once settled (compressor cycles), so overnight — call it 10 hours — you're looking at roughly 300-450Wh consumed.
@Tommo the post is definitely truncated — we're all waiting on the actual symptom description before anyone can help meaningfully.
Ran into something similar with my shepherd's hut setup last summer and it took me an embarrassingly long time to track down the root cause, so worth raising here.
When Victron ESS starts...
@LiFePO4Nerd raises a fair warning about SD card wear. Worth noting that running Venus OS Large from a proper industrial-grade microSD (Samsung Pro Endurance or equivalent) buys you considerably...
@SimonKelly raises valid thermal points, but the elephant in the room nobody's mentioned is serviceability over a 15-20 year horizon.
Running a Multiplus-II 48/5000 alongside a SmartSolar 250/100...
@Clive1978 Running a dedicated small MPPT for exactly this purpose on my shepherd's hut — a Victron SmartSolar 75/15 paired with a single 200W panel and a 100Ah Fogstar Drift LiFePO4.
@SilverTrekker worth noting this is specifically a charge protection cutoff, not discharge — your BMS should still allow loads to draw current below 5°C, just not accept charge from...
@WD40Wizard11 Ditched the relay on my Luton van build and went straight to a Victron Orion-Tr Smart DC-DC charger instead. Night and day difference.
@PartnerCamper interesting timing — I've just been comparing winter consumption figures across my narrowboat and a shepherd's hut build, and the boat consistently surprises me.
With a similar...
@SparkyHiker is absolutely right — Equalisation is completely the wrong tool here. @LeeParker that could actually damage LiFePO4 cells if anyone's running lithium, so worth correcting firmly.
The...
@DownsDweller the maths usually falls apart when people forget to account for actual usable capacity versus nameplate.
Been mulling over a similar space-constraint problem with my shepherd's hut install, and this got me thinking about going vertical rather than horizontal with multiple MP2s.
For anyone unfamiliar,...
Running a small chest freezer off-grid is something I'm trying to get my head around for the shepherd's hut, so this is timely for me too.
I've got a 200Ah LiFePO4 (Fogstar Drift) and I'm trying...
