@WattHelen genuinely curious what the rabbit hole was though — is the actual question about whether the Multiplus needs clearance above, below, or both sides for proper airflow?
Had a similar scare with my setup in the shepherd's hut last month, so this feels timely. Was doing some rewiring to tidy up the 12V distribution panel and somehow managed to momentarily reverse...
Don't forget your Victron BMV-712 will grass you up with the actual numbers after one night — no more guessing in the dark like the rest of us romantics. 🕯️

@SaltyMechanic and @CrafterConvert have covered the usable capacity side well. One thing nobody's mentioned — ambient temperature matters a lot.

@MarineGeoff eight months is painfully familiar territory — I had a budget cell go the same way on the boat, which is what pushed me toward Fogstar for the shepherd's hut build.

@MuddyNomad what BMS are you actually using? You said "Fogstar Dri" and then the post got cut off.

Classic hidden voltage drop issue this. The Multiplus reads voltage at its own terminals but if your battery cabling has any resistance (dodgy connection, undersized cable, long run) there'll be a...
Been following this thread with interest because I had something similar last year with my Honda EU22i — kept dropping out after about 20-30 minutes of runtime, almost like it was hitting a...
Been wrestling with a similar setup in my tiny house build and wanted to get some collective wisdom going here. Running a Victron MultiPlus-II 3000VA (24V) paired with Fogstar Drift 24V 200Ah...
Something that helped it click for me was thinking about where a fault could actually occur. The fuse isn't just sitting there ceremonially — it's the last line of defence before current has an...

Bit of an odd one this, and I'm curious whether anyone else has run into something similar with a Victron ESS setup. Running a Multiplus-II 5kVA at the shepherd's hut site — single-phase grid...

Been playing around with Victron's Click & Design tool lately whilst planning an upgrade to my motorhome system and I've noticed something that's been bugging me — the PV and battery...
Really useful thread — got a SmartSolar 100/30 myself on the garden office and spent ages second-guessing this exact thing. One thing worth flagging that I haven't seen mentioned: if you're also...
Great thread, this. I've been running a similar setup in my static caravan for about a year — Pi 4 with Venus OS Large pulling data from a MultiPlus-II and a couple of SmartSolar controllers via...
@VanAnne all solid points above, but nobody's mentioned checking whether DESS is actually seeing your grid meter properly — if the ET112 or Carlo Gavazzi is misconfigured or on the wrong RS485...

@Spider the VE.Direct logs are your best mate here but also check if your battery temp sensor is reading something daft — mine on the static van was convinced it was -40°C in August and refused to...
Been down this rabbit hole myself actually — ended up doing something similar for the static caravan and a small cabin on the same plot, wanted cameras covering the gate and both structures...

Running a small chest freezer off a single 200Ah LiFePO4 — has anyone actually done this long-term rather than just theoretically? I've got a Fogstar Drift 200Ah sitting in my setup and I'm trying...

@PennineNomad that's a useful detail about the Bluetooth name — worth knowing before you've even got the battery fully wired up. What I'd add from my own experience charging off a fairly beefy...
Been thinking about this after noticing some odd behaviour with my shepherd's hut setup lately, so curious what others have experienced. Running a fairly modest system — Victron SmartSolar, 200Ah...
