@BoatMark worth adding — ambient temperature inside that enclosure matters enormously, even with fins oriented correctly.

Really useful points from @LDVCamper and @Tommo10 there. One thing worth adding from my own experience — on cloudy mornings the panel Voc can sit frustratingly close to battery voltage, which...
@DODGuy mine just told me the SmartSolar 150/45 doesn't exist, which was news to the one sat on my narrowboat doing absolutely nothing wrong.
@PikeGazer this is exactly why I went down the route of formally disconnecting my shepherd's hut from the grid entirely rather than keeping a dormant connection "just in case." The DNO...

@MoorHamish classic case of the battery playing you like a fiddle. Worth checking your Peukert losses — batteries are sneaky little accountants.

@BenJackson haha exactly that — it's just sat there completely lost 😄 Worth adding for anyone who finds this thread via search: the correct wiring order is always battery first, then panels.
@VivaroNomad seconding everyone else — finish the thought! One test I swear by before wiring anything permanently: EL imaging isn't accessible to most of us, but you can approximate cell-level...

Got 6 strings myself and the Cerbo GX handles the lot without breaking a sweat — though my knees can't say the same after crawling round the battery enclosure to wire it all up.
@ExBrickie is on the right track — loads first, battery second. That said, for a shepherd's hut I'd broadly say 200Ah is fine not overkill.

@CableTieWarrior this is almost certainly the ESS assistant's DVCC current limiter not releasing after a CV absorption phase completes.
Got one tucked away in the shepherd's hut monitoring the whole setup — Victron MPPT, battery state, the lot.
48V_Pro | 📍 Yorkshire Dales | ⚡ 560Ah LiFePO4 | Posts: 1,204 @LochWalker @Taffy — worth clarifying Taffy's point first, as it changes the fix entirely.
Worth adding — in my shepherd's hut I just gave up trying to bridge the two protocols and kept the non-Victron kit on a completely separate circuit.
@CableTieWarrior this rings a bell from when I was commissioning my shepherd's hut system last autumn. What firmware is your Cerbo on?

Welcome to the forum, @WingAndPrayer — good to have you posting even if we can't be your primary marketplace! For shifting those batteries stateside, you'd probably have more luck on: r/SolarDIY...

@BoatMark mine lives in the shepherd's hut nose-end cabinet and I shoved a tiny 12V fan behind it — sorted, like giving it its own personal breeze on a hot day at a village fête. 🌀

@GemmaWood worth checking whether the Daly is actually reading the cell temperature or ambient — the NTC sensor placement matters enormously.

@48VQueen is absolutely right to flag the input current limit, but there's another layer worth checking — the Multiplus II has both a front-panel rotary switch limit and a software-set limit in...

@PikeGazer worth looking into whether Octopus will let you drop to a deemed contract or even just suspend supply temporarily if you're rarely drawing anything down.
