@ExJoiner19 yeah def finish the post — but while we wait, guessing you're mid-sentence on Fogstar Drift cells going into a 48V bank? Few things worth knowing for MultiPlus-II ESS in a garden...
Got a few bits I've been hoarding in the garage that need to go to a better home. BMS boards — couple of 4S 100A units and one 8S 60A. All pulled from working packs when I upgraded.
@CrispyMender raises a fair point about the Cerbo, but also check your BMS if you've got one — a lot of people wire their BMS charge-enable signal into the MPPT's remote on/off port and then...

@SimonKelly what's the actual use case here? That matters more than the capacity comparison. Had similar decisions on my narrowboat and the thing nobody mentions is physical constraints.
Been getting some odd temperature high alerts popping up in my Remote Console over the past few days and I can't pin down exactly where they're coming from. Running a Multiplus-II 5000 with a...

Running a small garden office setup here and this question is keeping me up at night as we head into the darker months. Currently have a single 200W Renogy mono panel feeding into a 100Ah Fogstar...

Anyone else gone through ripping out a factory-fitted charger/inverter combo and replacing with Victron kit? My setup came with a basic Xantrex unit when I bought the place — did the job for a...
@Gill1982 one more thing to check that nobody's picked up on yet — your battery voltage sense. If the MPPT is relying on its own terminal voltage rather than a remote sense cable run directly to...
@JohnDixon the hokey cokey is painfully accurate 😄 Just to add something practical for anyone still wrestling with this — once I'd connected mine up to VictronConnect and had a proper look at the...
Had exactly this on my shepherd's hut build last summer. The Multiplus was calling float at around 80% on my Fogstar lithium cells — frustrating doesn't cover it. Turned out the absorption voltage...
Really interesting thread this — reminds me of when I first wired up my static caravan setup and spent weeks convinced something was fundamentally broken. One thing nobody's mentioned yet: have...
Had this exact saga in my van conversion last winter — once you've ruled out the obvious (dust, temp, disconnected fan), grab a multimeter and check the fan's supply voltage while the unit's under...
@SimonKelly eight months is a decent amount of time to have it bedded in — what does your automation logic actually look like for deciding when to charge from grid vs discharge?

@PennineNomad the "two thin" is genuinely the most suspenseful thing I've read since the last series of Line of Duty.
Interesting decision point this one, and something I went through a similar thought process with on my motorhome-to-static-cabin conversion last year. The Pytes V16 is genuinely tempting — 16kWh...
Bit of a tangent from the main thread topic but this feels like the right place to post — anyone else find that installers (or even just the bloke who helped you on a Saturday) just bung in a...

Ran into almost exactly this dilemma when I wired up the shepherd's hut last spring — space was the deciding factor there too, and I suspect it often is. For those unfamiliar: with the Lynx BMS NG...

@LisaHunt88 the 60% output scenario is precisely why I always insist on testing under consistent conditions before buying secondhand.

@GazPrice that shepherd's hut comment really resonates — the garden office is exactly the same story for me. Come May, my Victron MPPT is hitting absorption by mid-morning and I've barely thought...

Interesting timing on this thread — I've been going back and forth on whether to run a parallel pair of Multiplus II 5kVAs in my shepherds hut conversion rather than just stepping up to a single...
