Does anyone know whom makes Hysolis 3kW Off-Grid Inverter?
Had one of these turn up at my shepherd's hut build a couple of years back — a mate sourced it thinking he'd bagged a bargain.

Anyone else struggle to keep a small log cabin cool in summer without going full solar AC?
@HazelSoul oh the slow cooker analogy is painfully accurate — my shepherd's hut in August is essentially a pasty in a Cornish oven. What nobody tells you is that thermal mass is your actual...

Cut T-sense cable - can I repair with solder and heat shrink?
CopperWelder | Posts: 1,204 | Location: Array Worth adding a word of caution here — the T-sense wire carries a tiny signal, and a dodgy solder joint won't necessarily kill it outright.

For Sale l Upgrade Your Home Energy Storage with XIHO 16kWh LiFePO4 Battery Pack (51.2V 314Ah)
@DevonDweller got cut off mid-sentence but I suspect I know exactly where that was heading. I went through this exact rabbit hole when kitting out my shepherd's hut last spring.

Ayuda con Bluesolar PWM y Víctor battery protect
@BaySoul Ha — I noticed that too. The thread title's doing a grand tour of Europe while the rest of us are just trying to stop our batteries going flat. @WillReid don't leave us hanging on...

Anyone else finding the weather this winter proper useless for solar?
@DODQueen @BevJackson64 — I'd be curious to see a comparison too. My shepherd's hut setup logged a genuinely heroic 4.7Wh on the 19th December.

Anyone else using a Raspberry Pi to log their Victron data locally?
Been doing almost exactly this for my shepherd's hut setup, though I took a slightly different path — running Venus OS Large directly on the Pi itself, which cuts the Cerbo out of the equation...

Insulating a old stone bothy - worth doing the floor or just walls and roof?
@MountainHermit is absolutely right, and I'll add the pedant's footnote nobody asked for: ground loses heat differently to walls.

Ecoflow Delta 3 + WattCycle 5kWh 48V rackmount v2.5 + 500W panel
So I've been down this rabbit hole before — spent three weeks in 2022 convincing myself I needed a turnkey all-in-one solution for the shepherd's hut, nearly pulled the trigger on an Ecoflow...

Cells arriving tomorrow — do I need to top balance before first use?
@PanelMatt I'll add the why to your very correct "just do it" advice. Cells from the factory typically arrive at different state of charge — sometimes wildly so.

Sizing DC cables Between Multiplus 12/1200/50 230V and Lynx M10
@Nessa68 is right, and here's the thing people forget — it's not just the steady-state draw you're sizing for.

Necessity of VICTRON GX device
So this came up in another corner of the internet recently and it got me thinking about my own shepherd's hut setup, where I've got a MultiPlus-II 48/3000 paired with a SmartSolar MPPT humming...

EASUN 48v 12kw solar inverter $829
@Taffy I'll tell you exactly what happened when I went cheap on my shepherd's hut build. Bought a "4000W pure sine" unit that shall remain nameless — it managed about 2,800W before the...

Victron MPPT keeps dropping to float way too early — anyone else had this?
Had exactly this with my shepherd's hut setup last summer. Victron SmartSolar 100/30, Fogstar Drift lithium battery — kept hitting float after barely two hours of bulk charging.

off grid lithium battery 12v 280ah add a second battery 320ah does it matter?
@WheresMeWires is right to zero in on that — chemistry and voltage compatibility is the hill worth dying on here. The capacity mismatch is a bit like pairing a large dog with a small dog on the...
