@Cleggy worth noting that the 200mm rule @LochLover mentioned gets really murky when your roof pitch is shallow — which most garden offices and shepherd's huts are.

Running a small chest freezer overnight is something I've been trying to figure out for my setup before committing to buying additional battery capacity. Currently running a 200Ah LiFePO4 (Fogstar...

Been mulling this one over as it's relevant to my own tiny house setup. I've got a Victron SmartSolar MPPT 75/15 feeding into a secondary Fogstar Drift lithium battery, with a Cyrix-CT 120A...
Got a Fogstar Drift 200Ah sitting in my cabin and wondering if it'll cope with running a small chest freezer overnight without completely tanking the battery. The freezer is a Subcold Pro 35 —...

Had a similar head-scratcher with my static caravan setup a while back. Running a Victron Multiplus-II alongside an MPPT 150/35 and a DIY LiFePO4 pack with a JK BMS, and I wanted to dial back the...

@QJ_Builds yeah, classic forum gremlin strikes again — we're all reading tea leaves here. That said, "battery output high" on a SmartSolar 100/30 usually points to one of a handful of...

Interesting one. The spec sheet looks compelling on paper but I'd want to see real-world data from UK installs before getting excited — we're not exactly blessed with the solar irradiance these...

@OldSailor @DevonDweller both solid points — had this exact nightmare on my motorhome last spring and spent three days convinced my Fogstar battery had gone rogue before realising the VE.Can cable...

QuietTrekker | 1,204 posts | ☀️ Solar Tinkerer Had this exact thing with a Quattro last spring. When it's mid-update and goes unresponsive, don't power cycle it — that's the killer move that...
Had this exact issue last winter with my Multiplus-II 48/3000. Was seeing it drop to float at around 80–85% SOC, which was driving me nuts — especially when I'm trying to get a full charge before...
Been running a Pi 4 (2GB) with VenusOS for about 18 months now and it's transformed how I manage the system.
@KenCross the wall insulation decision genuinely transformed my garden office situation. I went with 100mm PIR board between the studs plus a second layer of 50mm across the face — total overkill...

Had a similar head-scratcher with my Victron setup a while back, so thought I'd share in case it helps anyone else troubleshooting. Running a Multiplus-II 48V with a SmartSolar MPPT 150/35 and a...
Saw the announcement drop for the Victron Multi HS19 Solar 15k — genuinely curious what people here think about it landing in the UK market. From what I can tell it's aimed squarely at that...

@BodgeItAndScarper is right about the Orion, though I'd add — don't cheap out on the cable run to it.
Yeah, had the same faff with mine going into the static caravan setup. Once the engine detection and input thresholds are sorted, the bit that got me next was the charge algorithm — if you've got...

@CotswoldCruiser this is exactly the kind of project I've been eyeing up for my tiny house but haven't had the nerve to start yet.

Great thread this. I've gone a slightly different route — rather than Venus OS I'm running a bare Raspbian install with Node-RED pulling data from my Victron via VE.Direct to USB, then pushing...
@PV_Fan the old "Schrödinger's MPPT" — simultaneously working and not working until Victron decides to observe it properly 😄 Seriously though, had this exact thing on my garden office...
