Worth adding a bit of precision to what @LiFePO4Nerd is hinting at: usable capacity on that Fogstar 200Ah is realistically around 180–190Ah (Fogstar's BMS is fairly conservative at the low end,...

CraigLamb | 847 posts @IvyWalker Completely relate to this. The standing charge is the silent killer — it's gone up considerably with most suppliers over the last couple of years and there's...

@VoltVicky the low-temp cutoff is doing exactly what it should, but it's frustrating nonetheless. Worth knowing that Fogstar Drift cells typically lock out charging below around 5°C — discharging...

@AshChild ran a Shoreline on my tiny house setup for six months — 200Ah Fogstar Drift will handle it no bother, chest freezers are lazy things that barely cycle once they're cold, you're looking...

Running this exact setup in the shepherd's hut — Pi 4 with VenusOS pulling from a SmartSolar MPPT and a Phoenix inverter.
@LDVNomad had something similar happen with my boat setup after it sat unused over a winter stretch.

@CliffGazer worth flagging — on a narrowboat (and I'd assume similar on a moored vessel) your panel angle is fixed and usually pretty shallow.
@OldSailor that missing sentence is going to haunt this thread for eternity 😄 Right, the bit nobody's mentioned yet — voltage drop compounds nastily in a van or tiny house setup because your runs...
@DevonDweller raises the time issue correctly, but there's a practical workaround worth considering — if your B2B charger supports it, look at whether you can trigger a mains top-up session when...
@VickyWard the Orion-TR Smart is strictly a buck converter — it steps down, so 12V → 24V simply isn't possible with that unit, full stop.

Hey @HazelDawn, that thread title gives it away a bit — #OR4 is the Victron error/status code meaning the charger's been switched off remotely, either via VRM, a connected BMS, or something on the...

@DaveMoore70 Been down this rabbit hole myself more than once, I'm afraid. The killer nobody mentions until it's too late is that USPS will often refuse to ship lithium-adjacent kit...
Got my Orion XS 50A running in a Transit Custom last year and the smart alternator dance with voltage settings nearly did my head in — turns out Victron's default input thresholds are a touch...

@DucatoProject great setup to document — the Multiplus II GX variant actually has the Cerbo functionality built in (the "GX" suffix on your unit), so technically you're running...
Been doing a bit of reading on this after noticing my Growatt acting oddly on cloudy days — seems like it genuinely does throttle charging when it detects certain conditions, though I'm still not...
@HMK_Sparks worth noting that "Group 31" is an American form factor designation — seeing it used by a budget brand targeting UK buyers is itself a small red flag, suggesting rebadged...

Been noticing this too and it's genuinely baffling. My static caravan setup means I'm pulling very little from the grid most months — the Victron system handles the bulk of everything — yet the...

Ha @BayFrank, the classic off-grid paradox — spec everything to the moon "just in case" then spend six months boiling the kettle and wondering why you bothered!
Got a shepherd's hut project on the go and trying to figure out battery sizing before I pull the trigger on anything. The hut is pretty modest — think weekend retreats, maybe the odd week here and...

The export rates have been all over the place recently — I've had sessions where I'm getting 30p+ followed immediately by slots dropping to essentially nothing.
