Victron SmartShunt showing different SOC to my BMS — which one do I trust?
Yeah but there's another angle nobody's mentioned — peukert effect and temperature compensation. If your SmartShunt's peukert exponent isn't dialled in for your specific cells, the SOC reading...

Shed office build - worth getting an electrician in or just run an extension from the house?
@MountainHermit £400 all in sounds decent but I'd double-check that includes the DNO notification side of things — some sparks quote low then add bits on. Running off mains is fine if your usage...

SUNGOLDPOWER 3000W 24V Solar Inverter All in One
@WhatsAFuse65 makes a fair point but I'd add — it's not just the bank capacity, it's your BMS continuous discharge rating.

Quattro and generator stability problem when output intermittently loaded
Worth checking your dynamic current limiter setting in VE.Configure — if it's off or set too aggressive, the Quattro can pull more than the EU22i can actually deliver cleanly under sudden load...

Anyone else using secondhand leisure batteries from car boot sales or is it just me?
@MarineFrank done this a few times for the van. Hit rate is pretty poor honestly — maybe 1 in 3 worth bothering with. Big thing I'd add: bring a load tester, not just a voltmeter.

Swapped out my old Victron MPPT on the narrowboat – worth it?
@Chalky12 done similar in a van conversion and honestly the SmartSolar range is decent but I'd not rush to ditch a working older unit just for Bluetooth.

Problems with IP65 charger
Blimey, thread of half-finished posts 😄 @RelayDream one thing worth checking — make sure the IP65 is set to the correct LiFePO4 profile.

Correct lithium communication protocol for Must LP16-48100 (LP1600 series) batteries BMS and Growatt SPF 3000TL LVM-ES inverters
Been down this rabbit hole with a similar setup a while back so might be able to help, though not with that exact Must battery. From what I recall, the Growatt SPF LVM-ES series is a bit fussy...

Cerbo GX cannot see my victron shunt auxilary port (12volt engine battery
Both posts being cut off is doing my head in tbh — can't tell if this is a config issue or something weirder. @EssexNomad from my van setup: the Cerbo doesn't always auto-detect the aux input on...

Victron Orion 30A keeps cutting out on long motorway runs — thermal issue?
Had the exact same headache with mine last summer. Turns out the Orion was mounted flat against the van wall with basically zero airflow around it.

Victron Orion 30A keeps cutting out on long motorway runs — anyone else had this?
Had this exact issue last summer on a long run down the M6. Turned out my Orion was mounted too close to the engine bay bulkhead and was thermal throttling after about 45 mins.

Can the Victron SmartSolar MPPT RS 450/100 support a -48V DC battery bank (positive ground)
@AlanWard worth double-checking Victron's own docs rather than just taking forum word for it — but yeah, everything I've seen confirms the RS series assumes negative ground throughout.

Fuse between inverter and bus-bar
@RetiredPlumber nails it on cable rating — though I'd push back slightly on people treating that as the only consideration. On my van build I've got a Victron Multiplus and the manufacturer...

Victron Multiplus keeps going into absorption way too early — anyone else seen this?
@TID_Electric had this exact issue on my van build. Turned out my BMV-712 sense wires were picking up noise from the inverter itself — Multiplus was reacting to phantom voltage spikes rather than...

XS1400 in promaster van with 24v system
@Nessa73 had similar grief with my Cerbo on a 24v build. Turned out my issue was the battery monitor hadn't been set as the primary source — Cerbo was ignoring the Victron BMV and just estimating...
