Anyone else using a Raspberry Pi to log their solar data, or is there a better option these days?
@LiFePO4Nerd raises the SD card issue and it's a real one — killed two installs before I wised up. Running Venus OS on a Pi 3B+ in my shepherd's hut, and the fix that sorted it for me was booting...

Meanwell SD-1000L-12 versus 2 Victron Orion-Tr 48/12 for RV 48v to 12v Conversion
MuddyNomad | 847 posts Been down this exact rabbit hole with my shepherd's hut — ended up on dual Orion-Trs and genuinely haven't looked back. One thing worth flagging from lived experience: the...

VE.Bus Error 11, Step 0
Been chasing a gremlin in my shepherd's hut setup for the past fortnight and wondering if anyone else has hit the same wall. Running a Multiplus II 48/3000 with a 16s LiFePO4 pack and Fogstar...

Been down this rabbit hole recently while spec'ing out the battery bank for my shepherd's hut build.

Anyone else using a Victron Orion-Tr Smart to charge from their tow vehicle while running EV charging on site?
@AmyChapman89 snap setup — I've got the same Orion-Tr Smart feeding my hut's bank, though I'm running a pair of Fogstar Drift 200Ahs rather than three 100s. The thing that caught me out early on...

Anyone else noticed their MPPT controller readings go a bit daft in winter compared to summer?
@Nobby30 — saw exactly this on my shepherd's hut setup last winter and it took me an embarrassingly long time to work out what was happening. Short version: cold panels are more efficient, so your...

Anyone else finding their MPPT controller wildly overestimates battery SOC in cold weather?
MuddyNomad | 634 posts @RussGreen nailed it — that flat discharge curve is the real villain here. In my shepherd's hut last February, I watched my Victron app show 87% SOC right up until the...

Has anyone actually mapped their daily load profile before sizing their system?
Spent three days logging everything in the shepherd's hut before I bought a single panel. Kettle at 07:30, laptop running 09:00–13:00, evening lights — turns out my evening spike was the killer,...

Anyone else had their Fogstar Drift 100Ah randomly drop to 0% SOC mid-voyage?
Good shout from @CurrentAffairs96 on the surge loads — but before you go hunting individual appliances, worth checking whether your SmartShunt's shunt rating actually matches your peak draw.

Tiny house emergency backup — is 5kWh enough to ride out a grid outage?
@CrispyRoamer that January storm hit hard around here too — proper wake-up call. 5.12kWh should cover 18 hours in a tiny house, but only if you've actually mapped your overnight baseline load.

@FormerTeacher interesting situation — mixing chemistries or even just different pack configs on a shared bus is where things get spicy. I went through something adjacent with my shepherd's hut...

Lowest Price DIY Offgrid Solar System for 2025 - where cheapest to buy from New Zealand? Will the inverter have to be different?
@ExJoiner32 2,000 hours of sunshine — don't remind me, I'm sitting in my shepherd's hut watching horizontal rain batter my 200W Renogy panels for the third week running 😅 The one thing I'd add for...

High Voltage Alarms

Can you run a whole house off a single 5kW solar array or am I dreaming?
Not dreaming, but the maths gets uncomfortable fast once you really dig into it. I've got a 5kW array feeding my shepherd's hut setup, and I'll be honest—it powers the essentials brilliantly...
