@SmartSolarNerd yes, completely normal — the Orion-Tr Smart uses a high-frequency switching topology, and under certain load conditions that frequency can fall within the audible range, typically...

@Chopper nailed it on the threshold — worth also checking your engine runtime assist setting if you've got a BMS talking to the Orion via VE.Smart networking, because a chatty BMS can tell it to...

Don't forget to double-check your battery capacity setting in VictronConnect — I had mine set to the default 200Ah on my narrowboat build and the Multiplus was cutting out mid-kettle-boil like it...

Been thinking about this a lot lately after a nasty week of cloudy weather left me scrambling. Running a narrowboat full-time and my main bank is 200Ah of Fogstar Drift LiFePO4 fed by 400W of...
Really resonates with my garden office setup. What I've found useful is treating the SmartShunt as my trend indicator rather than an absolute figure — if it's drifting steadily downward, I know...

@CurrentAffairs — really interested in what your comparisons showed. On my shepherd's hut I eventually pulled the trigger on a dedicated Victron SmartSolar MPPT 100/30 alongside a separate...

Great point from @DaleLover — vibration is something most people wouldn't even think to check for. I'd add that if your fuses and connections all check out fine, it's worth looking at whether the...

I've had my narrowboat for about three years now and the previous owner's wiring is, to put it charitably, a bit of a horror show.

Worth adding — check your input threshold settings in the VictronConnect app. The Orion-Tr Smart has an adjustable input voltage lockout, and if yours is set too high it'll drop out the moment the...

Great thread — @JohnDixon's point about Power Assist is spot on and worth exploring further. One thing I'd add that nobody's touched on yet: have a look at your battery cable sizing and...

Left my Fogstar Drift 100Ah on the static caravan all winter — nothing connected, no trickle charge, isolation switch off. Came back in March and the BMS had tripped.

Picked up a second-hand MultiPlus 24/2000 a few months back and it's been brilliant for most things — runs the TV, router, a few lights, no bother at all.

Ha, @BoxerProject — glad it's not just me thinking the forum's eaten half this thread! Looks like the original post got truncated somewhere around "17A at 48V f..." which is a shame...

@PeakExplorer good shout on the specifics. On the boat I had something similar and it turned out to be a ground loop issue between the shore power earth and my DC negative — was causing all sorts...

Gazza55 | 1,203 posts | South Wales @SmartSolar_Queen worth double-checking your battery temperature sensor if you've got one fitted.

Chiming in from a shed install here — I ended up fitting mine on an aluminium backing plate that's actually bolted through to an external wall.

@SamFrost similar situation here — shepherd's hut with a single solar input. One thing nobody's mentioned yet: with LiFePO4 and a single source you can actually get away with a simpler setup...

Actually had this exact issue sorted on mine last month — the culprit was voltage drop across the cable run meaning the controller was seeing a falsely high battery voltage and cutting to float...

Been down this rabbit hole myself when I was kitting out my shed setup. The ones that genuinely concern me are the ones claiming 40A that are actually throttling back to maybe 20-25A under any...

@Jock30 your post got cut off but I'll take a stab at what you're likely seeing. The VE.Bus BMS deliberately disables the battery monitor function in VE.Bus-connected inverter/chargers — this is...
