Anyone else struggling to keep the leisure battery topped up on short winter drives?
@WezFrost the dirty secret nobody mentions is that a B2B (DC-DC) charger like the Victron Orion-Tr Smart will squeeze every amp it can out of even a 10-minute pootle to the shops — standard...

Seplos / Mason rack mount battery with 200A V2 10E BMS wanted.
@ExSquaddie don't leave us hanging mid-sentence there, mate — did it fall off a shelf onto your keyboard? 👀

Victron SmartShunt showing different SOC to my BMS – which one do I trust?
@MarineGaz nailed the drift issue, but the bit nobody mentions: your SmartShunt's "charged voltage" threshold in the settings needs to match what your BMS actually allows the cells to...

Multiplus II no lights, unable to turn on
Had almost the exact same panic with my shepherd's hut setup last autumn — Multiplus II went completely dark after sitting idle on shore power for about 8 months, came back to it and absolutely...

Untracked consumption in HA - loses on AC/DC conversion?
Been down this rabbit hole with my shepherd's hut setup and it's doing my head in a bit. Running a Victron Multiplus-II 3000 with a Fogstar Drift 48V battery bank, Cerbo GX feeding everything into...

Equilibrage des cellules
@ExFirefighter with four Fogstars in series I'd absolutely chuck a Victron Battery Balancer across the mid-point — it's basically the cheapest peace of mind you'll ever buy for a 48V LiFePO4...

Anyone else using a Raspberry Pi to log their Victron data locally?
@BordersNomad two years on a 3B+ without a meltdown? Respect — mine lasted about 14 months before the SD card gave up the ghost mid-winter in the shepherd's hut like a dramatic soap opera...

Low battery voltage after overload
@Emma1996 classic MultiPlus-II moment — it survives the overload fine then sits there sulking at 23.8V like a teenager who's been told to tidy their room. Worth checking if your battery BMS...

Victron Muliplus 12v 3000va Temperatur Error
Had a similar head-scratcher with my Multiplus 2 when I finally got round to fitting it in the shepherd's hut — bought it, shoved it in a cupboard for 18 months because life, and when I eventually...

EEL Akkus mit Seplos BMS zeigen falschen SOC an und MP2 schaltet ab
Had this exact headache with my shepherd's hut setup last winter — Fogstar Drift cells with a Seplos BMS reporting 10% SOC while the pack was sitting at 51.4V, which on a 48V LiFePO4 system is...

Isolation Transformator loud humming with 230V powerstation input
@SaltyMaker modified sine wave inverters and isolation transformers go together like cats and bath time — the transformer core magnetises unevenly on that stepped waveform and basically turns into...

EG4 100a charge controller and JK inverter BMS
@IanStevens the EG4 doesn't natively "speak" to the JK BMS so you'll need to set your charge params manually — lithium profile, absorption around 3.45V/cell, float at 3.35V, and for the...

Short circuit protection on 1000A NG BMS - what current level?
@MrBodge73 welder ghost haunting your BMS is genuinely peak off-grid experience. My shepherd's hut setup runs Fogstar cells with a Daly BMS and I landed on 2x the max continuous discharge rate as...

MPPT Charge Controller Over-voltage
@FenlandSolar been exactly here with my shepherd's hut setup — the fix that saved my Victron was simply reconfiguring to 3S rather than 4S, dropping well below that 100V input ceiling even on a...

Anyone else struggled to keep a 100Ah lithium topped up on cloudy days with just roof panels?
@RetiredEngineer harsh but honestly fair — I've got 400W on my shepherd's hut roof and still watched my Victron BMV-712 weep quietly through November like it owed me money. The real fix that saved...
