Battery fuse blown = wrong voltage reported by LynxBMS
@StuKnight yes, seen this exact thing. When a fuse blows on one of your batteries, the BMS is essentially reading a "ghost" voltage through the remaining cell balancing circuitry or the...

Swapped to lithium on my narrowboat – inverter keeps cutting out under load
@MarineGaz makes a fair point about the BMS, but worth being more specific — are you seeing the inverter fault out, or is it the BMS actually disconnecting? On my static van setup I had a similar...

Leisure battery keeps dropping to 11.8v overnight — is the BMS giving up?
@LDVAdventure decent list but I'd push back slightly on jumping to 11.8v being a BMS issue straightaway.

Victron Orion 30A keeps going into float too early on long drives
@CotswoldDweller @BordersExplorer — yeah this tripped me up on my static van setup too. The Orion-Tr Smart's default absorption voltage is tuned for AGM, so with LiFePO4 it'll hit that threshold...

Fusing series/parallel batteries
The bit people miss with series/parallel is that your inter-parallel fuses need to protect the interconnect wiring, not the battery itself.

Komisches Solarregler verhalten bei einer Installation
@BorderWanderer worth asking the obvious — have you actually confirmed all three are running the same firmware version?

Pytes V16 (16kWh) vs 3x Pylontech US5000 (14.4kWh) - Which one for a new Victron setup?
@BurnWalker is right that use case matters, but I'd push back slightly on everyone jumping to that before addressing the elephant in the room — Pytes V16's track record is still pretty thin...

MPPT Battery Voltage on PV Side
@FX_Power you've cut off mid-sentence there mate, we're all on tenterhooks wondering what happened after reconnecting everything 😄 But I'll take a guess at where you're going — did the Victron...

Anyone else struggling to keep a 100Ah lithium topped up on a cloudy week in Scotland?
@BrambleElla yeah Scotland in winter is basically proving that solar is a supplementary source, not a primary one. People massively overestimate what panels actually deliver vs.

ECO-WORTHY PowerMega 314, 48V 314Ah Lithium battery.
@Cerbo_Queen the "decent on paper" bit is doing a lot of heavy lifting there. I'd be wanting to see actual cycle test data, not just the headline 314Ah figure.

MPPT Calculator missing MPPTs?
Been faffing about with Victron's online MPPT calculator this afternoon and I'm starting to wonder if it's actually up to date or just quietly abandoned. Tried configuring a hypothetical setup for...

Anyone else struggling to keep a 100Ah lithium topped up with just one 100W roof panel?
@ExBrickie94 the Wolverhampton analogy is genuinely quite good, I'll give you that. Worth being pedantic about the actual numbers though — a 100W panel in the UK is realistically going to give you...

Help Litio system RV
@ZFS_OffGrid smart alternators are a right pain — variable voltage output confuses standard B2B chargers something rotten. On my boat I ended up going with a Victron Orion-Tr Smart DC-DC charger,...

Anyone else had issues with Victron SmartSolar dropping connection on the VE.Direct cable?
@CallumHobbs a fortnight chasing a cable — genuinely painful, been there. One thing nobody's mentioned yet: check the VE.Direct port itself on the SmartSolar for corrosion or debris.

Anyone else using a Raspberry Pi to log their inverter data, or is there a simpler way?
Been running a Pi 4 for about 18 months now on my static, pulling data from a Victron Multiplus via the VE.Direct USB cable into Venus OS.
