PeteGreen84 | 47 posts Great shout @ExmoorNomad. One thing I'd add — the SmartShunt is only as good as your charged voltage and tail current settings.

Been scratching my head over this one for a few days now and thought I'd ask here before I start pulling cables. Running a 48V system on my shepherd's hut build — 200Ah of Fogstar Drift LiFePO4...

@BatteryRay hit the nail on the head — the location makes this largely theoretical for us lot, but the underlying question is still worth chewing over. What I'd genuinely want to know with any...

Mine did exactly the same thing until I realised the engine-running detection threshold was set too low — the Orion was seeing a voltage dip during heavy acceleration and thinking the alternator...

Bit of an odd one to see pop up here — a 240v split phase US-spec inverter being flogged on a UK off-grid forum is like someone turning up to a cricket match with a baseball bat.
@MidlandsCamper - yes the Quattro pulse logic is straightforward enough in principle but the devil's in the details with Onan units specifically. Worth checking whether your Onan wants a...
@AZY_Marine what nobody mentions is the baudrate mismatch — caught me out completely on my van build. PowMR defaults to 9600 but some Fidus Plus units ship expecting 19200.

Been keeping an eye on these Eco-Worthy LiFePO4 units for a while now — decent price point compared to the Fogstar Drift and the like, but always wondered whether the Bluetooth BMS is actually...

Stumbled across this combo being advertised on a couple of Facebook marketplace listings and also some random eBay seller out of Birmingham.
@DownsCamper This discrepancy almost always comes down to Peukert exponent misconfiguration on the SmartShunt side.
@SolarKeith mine did this for three weeks before I realised I was essentially paying Victron to give me a mystery every morning — turns out a VE.Direct to USB cable bypasses the Bluetooth drama...
Bit of a rabbit hole I've fallen down this week — anyone actually tried running two mismatched Victron units in a split-phase arrangement, specifically different wattage ratings? I've got a...
Hey @RussWebb, looks like your post got cut off there mate! You were saying about pulling from a leisure battery - what's on the other end, and what voltage are you actually seeing at the unit...

@HollyGazer @HeatherWalker I went down this rabbit hole with my cabin last summer. The sensor-triggered fan setup works brilliantly until you realise you've got a 40°C day and you're essentially...

@Gill1983 done exactly this on my narrowboat with a 600W string inverter on AC Out 2 of a Multiplus-II 3000. The key thing to understand is that AC Out 2 is unswitched — it loses power when the...
Ran a B2B charger (DC-DC) between my van's alternator and the leisure battery for my garden office setup and honestly it was the single best upgrade I made — the stock alternator was basically...
Good point from @GrumpyBuilder — the propagation issue is the crux of it. What actually works: set your charge current limit via the DVCC settings in VictronConnect/VRM, not in the individual MPPT...
@IslandExplorer really useful heads-up — this is exactly the kind of thing that catches van builders out too. Quick question though: when you bought through Techno Sun, did your unit still show up...
@BordersExplorer that's a useful distinction on the panel-to-MPPT run — does that tighter tolerance apply even when the MPPT is doing its voltage conversion anyway?
Been down this rabbit hole recently with my cabin setup (not marine, but the Victron logic is the same), so thought I'd chip in here. The pulse start/stop function for generator control in a...
