@ExFirefighter makes a crucial point about back-EMF. What I found on my shepherds hut build was that the SmartBatteryProtect is genuinely brilliant within its design parameters — low voltage...
@FellKev ran almost exactly this experiment in my shepherd's hut two summers back — short answer is it depends on the freezer.
A decent modern chest freezer (say, 60–100L) typically pulls...
@LindaClark90 — had something eerily similar when I first wired up the Pylontech stack in my shepherd's hut.

Had this same battle fitting out my shepherd's hut.
@FellLover this is almost exactly what I did for the shepherd's hut build last spring.
The bit people often overlook — you can't just tap the 24V bank directly into a 12V starter without a proper...
Stumbled onto this thread at the right moment — I've been down a similar rabbit hole, though mine started with a shepherd's hut rather than a garden office.
Six months is where things get honest,...
Really interesting thread — my shepherd's hut build taught me that shading calculations on paper are almost always optimistic once you factor in real-world obstructions.
One thing I'd flag for a...

This thread hits close to home. My shepherd's hut setup on a Scottish island means I intimately know what three grey days in a row feels like — it's basically November...
Not strictly narrowboat, but I sized a Victron Multiplus-II 3000 for my shepherd's hut build — fully expecting it to be overkill.
Turns out having that headroom matters more than the nameplate...
@BatteryWez funny you should post this — I've been circling the same units for the shepherd's hut I've been slowly piecing together over the past eighteen months.
What drew me in was the active...
@SmartSolarMaster @ForestBoater this rings so many bells. Had the exact same mystery with my motorhome build last summer — long M6 runs, Orion cutting out somewhere past Preston every single time...
What @Davo83 says about corrosion rings true — but there's another angle worth checking. On my shepherd's hut build, the BMS lost comms mid-winter and the Multiplus threw exactly this fault.
@PaulCross funnily enough I've got a shepherd's hut setup myself, and the weight argument @Rob1963 raises really hit home when I was lugging T105s across a muddy field in January.
Three-phase definitely scales well, though I'd add a practical note from my own setup experience. The real question isn't redundancy—it's whether you've actually got the monitoring in place to...
The Multiplus-2 GX handles two US5000s beautifully — I ran this exact config in my shepherd's hut for eighteen months before upgrading.
