@JasonMoore the tip is basically a free components warehouse if you know what you're looking for. Done similar on the tiny house build. One thing nobody mentions — permanent magnet motors are the...

Worth adding that I've seen this in my static caravan setup too — JK BMS was cutting out intermittently and I spent ages chasing a supposed cell imbalance before realising temperature was the...

@CopperWelder a pasty in a Co-op bag left on a dashboard, more like 😄 Cabin's about 20m² and I spent two summers cursing before I actually thought about it properly.

@ExSquaddie the "review" language is doing a lot of heavy lifting there, isn't it — funny how reviews only ever go one direction. Worth flagging for anyone still grid-tied: if you're on...

@DODGuy raises a fair point about clarifying the question, so I'll add my two penneth from experience. When I set my MP2 to charger-only via VEConfigure, I specifically asked my DNO about grid...
@EcoFlow_Gal is right — the Multi RS uses a completely different VE.Can backbone rather than VE.Bus, so your Cerbo/GX device needs to be talking the right language or VRM just stares at it blankly...
@VDH_Boats @CotswoldNomad oh this brings back memories — I had mine tucked into the bulkhead of the shepherd's hut tow vehicle last spring and honestly the dropout pattern was maddening.
@SolarGaz that's my usual fallback too, but winter sun in the UK is genuinely pitiful — I'm in the north and some days my roof panels are producing next to nothing even at midday. Quick question...
@RiverFinn beat me to the DVCC point but also worth checking your absorption time isn't set to something daft like 1 hour in VictronConnect — mine on the narrowboat was doing the exact same...
@MikeCross had the same maddening dance on my narrowboat last winter. The Fogstar BMS is doing its job — it hits full voltage and quietly disconnects before the SmartShunt ever sees that tail...

Cleggy | 203 posts | ⚡ Off-grid since 2022 @ForestDaz really sorry to hear you're dealing with this — these unexpected post-update gremlins are the worst!

@CotswoldNomad makes a fair point, though I'd argue the per-head demand profile is actually what makes community systems so gruelling compared to a single-occupancy setup. Six years of continuous...
@ExSquaddie £34 a month bump and they still have the audacity to call it a "review" — mate, my Renogy panels paid for themselves faster than I expected precisely because the grid keeps...

DefenderAdventure | 1,847 posts On the boat I tackled this methodically. A 60W heated pet mat wired directly to a dedicated 12V circuit (not inverter-fed — pointless efficiency loss for a...
Seen something similar on my shepherd's hut setup — Cerbo GX on v3.79, Fogstar Drift 200Ah, MultiPlus-II 3000.
Good point being raised here. The Multi RS Solar's maximum charge voltage tops out at 58.4V for 48V systems, which matters enormously when you're selecting your battery chemistry. For a shepherd's...
@CumbrianWanderer this is almost certainly low-temperature lithium behaviour rather than a genuine BMS fault.
Ran a communal setup at a small holding years back — five static caravans sharing a single bank. Total nightmare to manage fairly tbh.
@VDH_Boats @PennineVanLifer had exactly this with mine mounted under the passenger seat — turned out it was basically sitting in a warm bath of recirculated air.
@AZY_Marine just to add a practical point that builds on what @VivaroWanderer and @ExFarmer90 have raised — even if your controller's absolute maximum input voltage technically covers that...
