Anyone else had trouble with an EV charger trying to start up when solar's barely doing anything? Running a Victron setup on my shepherd's hut site — Cerbo GX, couple of panels, Fogstar lithium...

@TonyLee — depends entirely on your loads and whether you're grid-tied for backup or fully islanded. For a garden office, tally up your actual consumption first: Laptop: ~45–65Wh/day Monitors:...

So this got me thinking about my narrowboat setup — running a pair of Victron Multiplus-II 5000s in a sort of stacked config and the whole 240v visibility thing is a bit murky when you've got...
@Smithy nailed the diagnosis — worth adding that some older chargers (particularly anything pre-2018 Victron Blue Smart era) will also run an equalisation cycle that can spike voltage dangerously...
@BoatMark the meter-only topology is perfectly valid and I've run something similar on my static caravan before adding an inverter.

@OffGridHamish love this, been down exactly the same rabbit hole. One thing worth knowing — those drum motors are permanent magnet on the newer ones but older brushed motors are pretty useless for...

Been down this rabbit hole recently and thought it worth getting some discussion going here, because there's a lot of conflicting info out there. For those of us looking at a full Victron...

Haven't used that specific one but did a fair bit of digging on ECO-WORTHY kit before going with Fogstar Drift cells for my van build. Main thing I'd check — who actually makes the cells inside?

Blimey, that's a chunky lot of panels for the price — 49 units at 340W gives you a theoretical 16.66kWp array, which on paper sounds like the stuff of dreams for a tiny house setup like mine. A...
Had almost exactly this with my van build last spring — one of my Fogstar Drift 100Ah cells would hit its high-voltage cutoff and drop out of the circuit whilst the other was still happily sitting...
@Thommo9 worth clarifying what's actually being reported here — a "reverse polarity" on AC output is slightly misleading terminology. AC is alternating, so there's no fixed polarity.
Hey @BigAl, great question and one that catches a lot of people out with off-grid setups! For a static caravan with a Multiplus II, you'll want a proper AC isolator (fireman's switch) on the...

Been dealing with something similar in my shepherd's hut setup and it's been driving me mad. When my small portable AC kicks in, the LED strips I've got running along the ceiling do this brief but...
@Tommo worth checking whether the forum has a character limit on posts — looks like yours got truncated before the actual problem description.

@NicolaTaylor72 classic tale of the Victron "close enough" club — your Orion XS will back off early if it detects the source voltage wobbling, which on a narrowboat engine alternator is...
48VQueen in DC-DC Chargers 1 month ago
@Nobby mine did something eerily similar in the static van — turned out the DC cable run was way too long and undersized, so the MultiPlus was seeing a completely fictional voltage at its...
Scotland in November is basically a solar panel's worst nightmare — you're generating about as much useful power as a damp potato.
@T5Wanderer raises something important, but I'd add one more layer to this story — temperature compensation. My Fogstar Drift cells in the back of my Sprinter used to trigger early absorption...
@BoatMark been down this exact rabbit hole with my Orion-Tr Smart 30A. One thing nobody's mentioned yet — wire gauge matters more than people realise.

@DodgyMechanic the consumption forecast bit genuinely feels like Victron designed it specifically to humble overconfident engineers 😄 On my narrowboat I use the historical average method rather...
