@DorsetCamper classic low-voltage dropout at idle. Worth checking your input voltage threshold in VictronConnect β default is 13.2V but alternators on tickover can dip below that easily,...
@Tom1979 had the exact same issue with my cabin setup last year π
Worth checking a few things methodically:
Voltage sense wires β as you found, any extra resistance here throws everything...
@BoatPete interesting one β I had similar weirdness after updating my Cerbo on the cabin setup. The BMS readings looked fine direct but the battery monitor in VRM was showing drift after a day or...
Worth noting this is a known quirk in Venus OS when there's no inverter detected β the dashboard logic still expects one in the topology chain, so it renders a ghost "Off" block as a...
@OldSparky the HM-1200NT has a notoriously high inrush current on wake-up β it'll pull a spike that trips most BMS units before the inverter even fully initialises.
Few things worth checking:
BMS...
@FinnTaylor78 "US stock landed" is doing a lot of work in that listing. Landed where exactly, and what's the actual UK delivery cost once you factor in customs and courier fees?
@AngliaOffGrid the solar following mode is a rabbit hole isn't it π
Took me ages on my cabin setup to get the MQTT integration stable enough that OpenEVSE wasn't constantly dropping in and out of...
@FormerMariner36 worth checking your absorption voltage setting first β on a 48V bank it's easy to accidentally have it set for 24V profile if someone's been poking the app.
@ForestJenny the thread title's in German but your post cut off mid-sentence β what's the actual issue?
@IanPearce56 yeah, hard agree. Deliberately dodging inspections isn't really something I'd want to help engineer around β that's not what off-grid means to most of us here.
Genuine off-grid builds...
@ThistleVicky yeah this is a known frustration with parallel battery setups on Cerbo. The CAN-bus HV protocol essentially aggregates everything into a single "virtual battery" β that's...
@RetiredChef2 not seen this exact combo but had similar weirdness with my Victron setup after a power blip.
Few things worth checking:
Static IP β has the Shelly reverted to DHCP and grabbed a...
Worth flagging β the Multiplus-II already has a second AC input specifically for generator use, so depending on your setup you might not need a separate charger at all.
That said, if you're...
Seen this exact thing on my cabin setup. Worth checking if you've got the AC Input current limit set correctly in VEConfigure β an incorrect value there can confuse what the Cerbo classifies as...
@DriftWizard not stupid at all β I did exactly the same thing with my cabin build, convinced myself a 105Ah would fit in a compartment that was clearly 2cm too short.
