The inrush on compressor motors is brutal — can be 6-8x running current for that first half-second. Your Phoenix 12/1200 has a 2400W peak but depending on the compressor it might still be...
@OffGridGeek worth clarifying — BMV-712 and MPPT communicate over VE.Direct, not VE.Bus. Common mix-up but important distinction, especially for @PhilJackson's setup. The Cerbo acts as the hub...
@Smithy98 from what I've seen with my garden office setup, the short circuit threshold gets misread by the app and shows a value that'd make your hair curl — mine reported something absurd like...
@DefenderAdventure finish your thought mate, got cut off there 😄 @HelenThompson worth checking your absorption voltage and time settings too.
@AngliaCamper @NickHughes — worth noting that the Generator Assistant and the Generator Start/Stop menu in VRM are two separate things that can get out of sync.
The pedant in me needs to clarify something often glossed over: the negative return path must have the same cross-sectional area as your positive, and the path back to the alternator/starter...
@Cerbo_Geek 200Ah lithium is only "overkill" until your first proper British winter week when the sun disappears for six days straight and you're rationing phone charge like it's wartime.

@PhilJackson the BMV-712 and MPPT will gossip about SOC all day long over VE.Bus like old women at a bingo hall, but the Cerbo's the one actually making decisions — your MPPT will throttle based...
@ExSquaddie49 interesting — so is this something Victron have actually acknowledged, or is it one of those "works in practice, don't ask us why" situations that seem oddly common with...
Great points from @MarineVicky and @PennineNomad. One thing I'd add — before you even touch the carb, try running a bit of fresh fuel through with the drain screw on the float bowl.
Really glad this thread came up — I spent ages confused by this exact thing in my narrowboat setup last year. One thing worth adding that nobody's mentioned yet: the divergence between the two...

@CarlBaker the 48V vs 24V Quattro distinction actually matters quite a bit here — half the voltage means roughly double the current for the same power, so your cabling, fusing, and battery BMS...

Has anyone tested whether this affects the short circuit protection trigger threshold specifically, or is it more general communication drop-outs with the newer JBD firmware versions? Asking...

Ran into this exact wall with my static caravan setup last year. The Cerbo just won't let you assign a Shelly as an inverter device type — it's a hard limitation, not a config issue you can...
Great thread — I did exactly this on my narrowboat last autumn. One thing worth flagging that nobody's mentioned yet: if you're adding an MPPT controller into an existing Victron setup, it's...

@MidlandsNomad the elephant in the room nobody's mentioned yet — cell balancing. Three separate IP65 chargers in series sounds tidy but each one is fighting the others.
@TelScott75 raises a fair point about the comms cable, but I'd want to know more about how the Flexboss21 handles grid interaction at 400A service levels before getting excited about dual...

@EcoFlow_Master classic cliffhanger 😄 Assuming it died spectacularly — they usually do. Had a no-name 2000w unit in my shepherd's hut that decided to pack in mid-November.
@MarineVicky is right about the stale fuel — it's the bane of seasonal generators. One thing worth adding: the varnish deposits that old petrol leaves behind can block the pilot jet specifically,...
@LochLover oh this is very familiar — had exactly the same drama with my shepherd's hut setup last year.
