@BordersExplorer had this exact drama with my 100/20 last summer. One thing that caught me out — VictronConnect needs to be a pretty recent version to see some of the newer dongles properly.
Haha this thread is basically a series of incomplete sentences now 😂 @EdCampbell84 inverter standby is a good shout but my money's actually on reduced solar input being underestimated.

Been lurking on this thread and it's got me thinking about my own situation — hope you don't mind if I piggyback with a related question. I'm setting up a garden office and eventually want to add...

@CaddyDream finishing @LisaHunt88's sentence is very wholesome, well done both 👏 Anyway @CamperCarl — think of your Multiplus like a bouncer at a club.
@ST_Builds had almost identical on my narrowboat last winter — MultiPlus-II 12/3000 paired with a 200Ah Fogstar Drift.
Had the same grief with mine last summer. Partial cloud cover and the thing would just... dither. Voltage hunting all over the place instead of settling on a proper MPP.
@DustyNomad had almost the exact same thing with my SmartSolar 100/30 on the cabin last February. Turned out to be the VE.Direct connection had worked itself slightly loose — controller looked...
Same battle every summer mate. I've got a Victron SmartShunt keeping tabs on my setup and honestly the data is eye-opening — a decent 12V fan is fine, but the moment you're tempted by a compressor...
Good shout from @LiFePO4Nerd on the maths, but the real-world wrinkle on a narrowboat is ambient temperature swings.

Had exactly this with my Smart Lithium 200Ah bank last winter. The BMS was triggering low-temperature cutoff during the early hours — typically around 3-4am when ambient in my cabin dropped to...

@RussHunt82 just to clarify something pedantic but I think it matters here — are you certain the negative AcPowerSetpoint is actually being written to the correct path on the DBus, or is DESS...
CliveKnight | 634 posts | Array Converted a shepherd's hut a few years back and made the classic mistake of obsessing over the walls while treating the floor as an afterthought — single layer of...

Had this exact scenario play out on my static caravan setup last winter — LiFePO4 bank (non-smart, no comms) hit low temp cutoff on a particularly grim February morning, BMS disconnected the load...
@CopperSparky the Orion-Tr Smart has a known quirk where it gets stuck in absorption like a toddler refusing to leave the playground — check your tail current threshold in the VictronConnect app,...

RustyTinker | 634 posts | 🔧 Cabin & Motorhome Had this exact headache in my motorhome last winter.
Standing charges are basically a subscription fee for the privilege of occasionally being disappointed by the grid — my static caravan's Victron/Fogstar setup means I've seriously considered...

Been down a similar rabbit hole with my narrowboat setup — Victron Multiplus II paired with a bank of Fogstar Drift LiFePO4 cells and a custom BMS that spits out data over RS485. The triac driver...
Been mulling this over for a while actually. The EasySolar-II GX is a tidy all-in-one unit but I've been wondering whether there's any real advantage to splitting it out into discrete components —...
@Pylontech_Queen good start but worth flagging the voltage drop issue that catches everyone out on 12V systems. At 2,000W your theoretical draw is ~167A, but factor in inverter efficiency...
My shepherd's hut runs on a pair of Fogstar Drift 12V 100Ah cells and honestly the plastic casing is either the hero or the villain depending on the day — it's survived being sat on by a sheep and...
