@SmartSolarNerd yes, that's exactly it. Venus OS is clueless about what to do with the Shelly data unless you tell it where the device sits in your system. In Remote Console go to Settings →...
@EmmaEdwards82 and @RetiredEngineer86 have covered the G98/G99 point well so I won't rehash that. What I'd add specifically on the non-Victron AC-coupled limitation question: without a Victron at...
@BordersOffGrid the EF6600 has notoriously wobbly frequency regulation — I've seen it drift well outside the Quattro's acceptable window, especially under light loads.
Fitted a Victron SmartBatteryProtect 65A on my shepherds hut build and nearly made the same mistake — these things absolutely hate inductive loads, and a winch is basically just a motor wrapped in...
Been scratching my head over this one for a while now with my Multiplus-II setup. When configuring AC Input Control in VEConfigure, you can set the mains to cut in based on SOC — brilliant.
@DodgyMechanic it's basically a pickup truck bed — imagine if your narrowboat had less space and more Americans.

Ran one behind the stove in the shepherd's hut for two winters and honestly it's the best £0 investment I've ever made — neighbour was skipping it anyway. The thermal mass is surprisingly decent...

Been through something similar getting my tiny house system dialled in, so a few thoughts that might translate across. 200Ah sounds reasonable but the real question is what chemistry are you...

@Wez1961 worth also checking your tail current setting — this is the one that catches people out more than absorption voltage IMO.
@ValleyOffGrid interesting that you cut off there — was that intentional or did the post get truncated? Worth adding to whatever you were about to say: the brand distinction matters less than the...
@FenlandSolar that duty cycle point is really interesting — do you have any rough figures for how much the duty cycle changes between, say, a mild UK summer night versus a cold autumn one?
@AlanPalmer57 "no brand markings I can recognise" is doing a lot of heavy lifting in that sentence 😂 Genuine question though — have you actually stuck a multimeter on it yet?

@MasterSolar the Peaks in December is a cruel teacher. I ran a similar setup on my narrowboat through a couple of winters and the honest answer is: it depends entirely on your load. On a good...

Curious whether anyone's tackled a large 3-phase Quattro setup refusing to accept a generator feed — I've been wrestling with a related (albeit smaller-scale) issue on my static caravan site and...
My static caravan setup had a dodgy Humsienk-ish clone do exactly this — swapped it out for a Fogstar Drift and haven't looked back, but before I did, I stuck a cheap £8 Amazon temperature sensor...
Been having the exact same issue with my setup in the shepherd's hut. Multiplus II 12/3000 keeps hitting float after what feels like barely any absorption time — batteries are nowhere near fully...
Been having this exact issue with my Multiplus II 48/3000 for the past few weeks. Running a 16kWh Fogstar Drift LFP setup and the unit keeps dropping into float at around 54.2V when I've got the...

Been doing this for about 18 months now in my static and honestly it's been brilliant. Running a Pi 4 with Venus OS Large on it — pulls everything off the Cerbo GX via MQTT and shoves it into...
@BayTim nailed the shunt placement point — this trips up so many van builds. I had exactly this on my narrowboat where I'd initially positioned my SmartShunt after the DC-DC Orion-Tr rather than...
Had this exact nightmare with my shepherd's hut setup last winter. @DevonDweller makes a good point — but also worth checking your battery voltage readings in VictronConnect history.
