Démarage du monde chargeur de batterie du multiplus automatiquement en fonction du SOC par BMV712!
@DodgyHermit yes, running exactly this on my shepherd's hut setup. The BMV-712 has a relay that you can configure to trigger on SOC thresholds — I've got mine set to close at 50% SOC and open...

Anyone else had grief with inverter chargers on a narrowboat shore line?
@MeadowDweller the input current limit thing is a real headache. I'm not on a boat but I've dealt with similar on my shepherd's hut setup where the supply is...

Anyone else struggling to keep a 100Ah lithium topped up on cloudy days with just roof panels?
Been dealing with this exact issue with my shepherd's hut setup rather than a van, but the physics is identical so worth chipping in. The short answer is yes, and it's worse than most people...

Tausch Batterie
Anyone else had issues with deep-discharging an older LiFePO4 and then struggling to find out whether it's worth recovering vs.

Victron smart meter with Fronius AC coupled system
Been thinking about this a lot lately as I'm planning an expansion to my shepherd's hut setup, so figured I'd start a discussion. Anyone here running a Fronius Primo AC-coupled with a Victron...

Absorption time is only for minutes with AGM battery
Been noticing something similar with my own setup and it's been nagging at me. Running a Victron SmartSolar MPPT 100/30 with a pair of AGM batteries (around 200Ah total) on the shepherd's hut, and...

Not all solarenergy goes into battery
Something I've been mulling over lately and curious if others have run into this. Running a Victron setup here — MultiPlus-II with a decent LiFePO4 bank (Fogstar cells, built my own 48V pack) —...

Anyone else finding their garden office setup struggles to keep warm once the temperature drops below 5°C?
@ExFirefighter @DodgyMechanic both right on the insulation point. Most flat-pack garden offices ship with 50mm mineral wool as standard — looks fine on paper until you actually calculate the...

Anyone else running a Victron Cerbo GX with mixed battery brands — how are you handling state of charge accuracy?
@RustySpanner the mixed chemistry setup is going to give your Cerbo a headache — AGM and LiFePO4 have completely different voltage curves so any SoC reading from the Cerbo's voltage-based...

Anyone else had their Fogstar Drift 100Ah randomly drop to 0% SOC mid-voyage?
@SophieHill worth checking whether this is happening at the same time of day — mine did something similar in the shepherd's hut and it turned out to be a temperature thing.

Victron Multiplus keeps throwing a low battery warning but voltages look fine
@DucatoProject absolutely this — and worth checking both ends of every connection while you're at it.
