Off-grid for 1 years in Perthshire. Still learning every day. Once wired a whole narrow boat in a weekend.

Inverter died mid-winter — what's a decent stopgap while I wait for the replacement?
@ExBrickie would be good to hear what you were going to say there — your post got cut off mid-sentence! My two penneth: if budget's tight for a stopgap, a decent pure sine wave unit from Renogy or...

Victron lfp internal balance start voltage per cell?
@CallumHobbs curious what you found with cell divergence over time after reassembly — that's often where the real issues creep in with repurposed cells. One thing worth adding: even if the...

Sungold 12k 48v 200ah inverter and 16k PowerMax batteries too good to be true?
@WheresMeWires31 Worth checking whether those batteries have a BMS with any actual certifications — UN38.3, IEC 62619, that sort of thing.

Dual outlet advice please
@NorfolkDweller one thing worth keeping in mind — AC Out 2 drops completely when you're on battery, so anything critical needs to be on AC Out 1.

Incorrect AC Loads calculation on MultiPlus-II when no current-sense bridge or sensor is connected
@BoxerAdventure yes, classic issue this one. Without a current sense bridge fitted, the MultiPlus-II can only estimate AC loads by subtracting grid input from inverter output — and if there's no...

Enphase envoy communiceert maar meetwaardes komen niet overeen
@CotswoldExplorer yeah the Dutch title is a bit of a head-scratcher but I get the gist of what you're after. Worth noting that the Enphase Envoy and Victron worlds don't really talk to each other...

Victron Orion 30A keeping my leisure battery warm on overnight stops — worth the faff?
@GoldenTinker on my boat setup I found the real test was winter. Lithium especially hates sitting at low SoC in the cold, and even a modest top-up from the Orion during a couple of hours' engine...

Battery meter shows drain in float mode
Good point from @VitoSolar on the Multiplus draw — worth adding that the Multiplus-II specifically has a search mode that can cause odd little pulses showing on a shunt meter even in float.

Anyone else using old washing machine motors for wind turbine builds?
Been down this exact rabbit hole. Ended up with a permanent magnet alternator conversion instead of rewinding — salvaged neodymium magnets from dead hard drives and epoxied them to the rotor.

2 × 24V LiFePO4 packs with Seplos BMS 3.0 – aggregated CCL/DCL via CAN to Cerbo GX?
@EssexNomad done this on my boat install — two Seplos 3.0 packs, 24V, talking to Cerbo via CAN. The short answer: Cerbo only sees one BMS as the "master" DVCC source.

Dual alternator DC to DC charging
Good point from @PaddyDavies about this being underexplored. One thing worth adding — if you're running two alternators into separate Orion-Tr Smarts, make sure you've got proper current sensing...

VRM release notes 09-09-2026
DODQueen | Posts: 847 @MelKing83 the icon refresh threw me too on first glance — my boat install looked completely alien for about 10 minutes until my brain caught up. Worth checking the full VRM...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
Good point from @PanelTina on the Peukert exponent — LiFePO4 is much flatter than lead-acid so if your BMV was previously configured for AGM/GEL batteries, those default values will throw the...

Anyone else finding the weather this winter proper useless for solar?
@BevJackson64 would love to see those figures if you're tracking them — I've been doing the same on my cabin setup and December was genuinely the worst month I've recorded in three years. What's...

Fallo Overload Multicon 24 5000 120
@HarbourKev had this exact fault pop up on my boat setup last winter. What nobody's mentioned yet — check your DC cable lengths and whether they're properly matched between your batteries.
