@BevJackson64 the good news is Victron already solved this for you — the VRM Portal (free) will log everything remotely once you stick a Cerbo GX or even the cheaper Venus OS on a Pi in the...
Good thread this. Worth noting that for UK buyers the immediate practical impact is minimal — UKCA/CE marking governs our market, and Victron's GX comms stack is European-developed anyway.
@MelKing83 the short answer is: don't do it in series, obviously — @Rob1963 has that covered. But there's actually a legitimate case for keeping a lone 12v as a completely isolated auxiliary bank...
@24VGeek this is very much my specialist subject, having nursed a few cells back from the brink in my garden office setup.
The key test I always run first is internal resistance measurement — grab...
@Chopper54 one thing nobody's touched on yet — the 150/35 won't wake up if your panel open-circuit voltage is too close to battery voltage.
The bit that catches people out with the MultiPlus-II specifically is that it does not provide allpolige Trennung on its own when transferring to island mode — the neutral is bonded internally,...
@ExFarmer18 nails the bottleneck point — and it's worth spelling out why for anyone new to this: a lithium at, say, 20°C will happily gulp 40–50A from your alternator, but the B2B charger is the...
@ExBrickie31 raises a good point about hardwired outputs — worth adding that if you're going down that route, you'll want to check whether the inverter's output terminals are rated for the cable...
@JimWilson the 80 Series is actually a brilliant candidate for a proper aux setup precisely because it's old enough not to have smart alternator nonsense to contend with.
@GeorgeJohnson83 worth knowing that the MultiRS sits in a slightly odd position regulatory-wise for a garden office — it's a single-unit inverter-charger-MPPT combo, which Victron have essentially...
@AngliaOffGrid is absolutely right about the standing charge being the silent killer — and it's only going in one direction.
Scotland in November is basically a solar panel's worst nightmare — you're generating about as much useful power as a damp potato.
Been scratching my head over this one for a while now and figured I'd get some other perspectives before committing.
After months of dithering I'm finally pulling the trigger on a proper inverter/charger setup for my garden office.
@Tango the narrowboat context is interesting because you've got a genuinely different problem to a motorhome — you're often stationary for days, which means no alternator top-up from driving.
