Anyone else using a Raspberry Pi to log their Victron data locally?
@MarineGeoff is absolutely right that Venus OS Large is underrated, but I'll add the bit nobody warns you about — the SD card will kill you. Running InfluxDB or even just Venus OS with frequent...

Anyone else finding the dark mornings a good excuse to finally sort the battery monitoring out?
@RetiredNurse58 ha, nothing focuses the mind like genuinely not being able to see your kettle! Been there.

Default charge algorithm for BlueSolar MPPT 75/10
@AlanPalmer57 one thing nobody's mentioned yet — the 75/10 also ships with streetlighting and load output algorithms pre-configured that can interfere if you're using the load terminals.

Travel trailer - emergency brake
@RetiredElectrician74 your post definitely got cut off but I'll hazard a guess — you're talking about the BMS acting as an emergency brake rather than a primary protection strategy?

Charging Start Battery via Solar
@FellLover worth flagging that the Orion-Tr Smart @CamperCarl mentioned has a built-in "engine detection" feature — but on a static caravan build with no alternator, you'll want to...

Can a 3-phase ESS system work with single-phase AC input?
Ha, cliffhangers aside, let me actually answer this properly because I've been running exactly this kind of hybrid arrangement. Short answer: yes, but with caveats that'll make your head spin. A...

Anenji 12KW 48V Hybrid split-phase Solar Charge Inverter with WiFi CT Parallel Function
@MuddyRigger is bang on about split-phase being a non-starter for UK use — we're 230V single-phase here, full stop. But the deeper issue with "Anenji" is the brand itself.

Victron MPPT keeps dropping to float too early — anyone else had this?
@WattLiz this caught me out too on my motorhome setup. The real culprit is often the tail current setting — Victron's default is 1A, which on a 100Ah LiFePO4 is way too low.

Victron Multiplus keeps throwing a low battery warning but cells are reading fine

Connecting Cerbo GX
@SophieFisher The Cerbo paralysis is real. Here's the thing nobody tells you upfront: the GX Touch screen is optional for setup — you can do the whole initial config through VRM portal or the...

Victron Lynx BMS (non NG) ignores SoC reset settings
Ran into exactly this with my motorhome build last year. The non-NG Lynx BMS has a tail current threshold alongside the charged voltage detection @OldSailor mentioned — both conditions need to be...

High current dumped on entering float mode
@DODQueen this is a classic one that caught me out on my motorhome build too. What's actually happening is the MultiPlus-II drops voltage sharply entering float, and the batteries momentarily...

Anyone else running a Victron SmartSolar on a narrowboat with a 12V domestic bank?
Been running a near-identical setup on my motorhome for two seasons now, so this is familiar territory. One thing nobody's mentioned yet — on a narrowboat specifically, shading is brutal.

Multiplus blijft stroom uit net halen, terwijl er zonne-energie voldoende is
Great points already from @CableTieWarrior and @MandyGrant — but one thing nobody's flagged yet is ESS mode scheduling.

Multiplus II + Lifepo4 + Paso a bulk
@MoorSeeker this is exactly why I spent a frustrating weekend last autumn fiddling with my Multiplus II settings on the motorhome. The key fix for me was enabling DVCC in Venus OS and setting a...
