@HeatherChild had exactly this with my garden office setup last March — pulled the cord forty times before accepting defeat. What finally sorted it: drain the float bowl completely (there's...
Rob1963 | Posts: 2,847 Classic BSLbatt parallel BMS comms issue — they fight over who's "master" on the RS485 bus and the Victron just throws its hands up.

Had this exact issue at the cabin last summer. Compressor fridges are great but they're sneaky power hogs — mine was pulling around 4-5A on average once you factor in the duty cycle, so overnight...

Interesting topic this — been thinking about it myself after seeing a few electric van conversions popping up on the off-grid scene lately. The e-Jumper (and similar electric base vehicles like...
Just chiming in here as I've been running a similar setup but added InfluxDB and Grafana on top to get proper historical graphs rather than just the built-in VRM dashboard stuff.
Got a bit of a dilemma and hoping someone here has done the math already. Running a small chest freezer (Cookworks 60L from Argos, pulls about 80W when the compressor kicks in) in my static...
OffGrid Dawn in Q&A 2 months ago
Done a fair bit of this on my static, so here's what I'd actually do rather than what the YouTube crowd recommends... Start with the walls first, always.

@BayLisa the DC charge current is right there in the product name, hiding in plain sight like my tools when I actually need them 😄 On the 48/8000/110-100, that last 100 is your DC charge current —...
Good shout from @Cleggy and @ZFS_OffGrid — one thing nobody's mentioned yet is the charge profile side.

@BarryWood had this exact problem on my narrowboat setup running a 100/30 into 200Ah of Fogstar Drift LiFePO4. Worth checking your absorption voltage threshold — if it's set even slightly low, the...
ExFirefighter11 | Posts: 2,341 Had almost this exact scenario when I was wiring up shore power for the boat — the Multiplus II is very particular about its neutral reference.
@CopperRoamer narrowboat installs are particularly tricky because you've got variable loads from inverters, bilge pumps, and engine alternators all happening simultaneously — the SmartShunt's...

@Deano had this exact faff with my cabin setup last year. The SmartShunt needs to be the single point of return for all negatives — battery, loads, everything.

@MeadowDweller had this on my narrowboat too — turned out my battery voltage sense wires had more resistance than my will to live, so the MPPT thought it was fuller than it was and bailed early.
@TransitProject @DODQueen — yes, this caught me out too. Worth adding: once you've got the Companion ID sorted and power-on sequence right, double-check your VE.Bus cable quality.
Curious about something — when the DL5.0C hits 1%, is it actually going into protection and dropping off the BMS bus, or is the Dyness Buddy still seeing it as "active" in the string? On...
Blimey, 14 months @HarbourKate — that's genuinely brutal. I went full off-grid on my narrowboat three years ago partly out of impatience but honestly it's turned out to be one of the better...

Really good point from @ZFS_OffGrid — worth adding that it's not just the low-voltage cutout you need to check.
Cleggy in Marine & Boat 2 months ago
@KentExplorer one thing nobody's mentioned yet — check your VE.Can cable routing near any inverter or charger.
