On my boat I just used a Victron pre-charge resistor wired in for about 3 seconds before the main contactor closes — dead simple, costs about £3 in parts, and suddenly your BMS stops having an...
When my boat's BMS pulls the plug mid-charge, the Victron just sits there looking confused like a Golden Retriever that's lost its ball — absorption voltage with nowhere to go.
My Cerbo knows what my BMS had for breakfast — good luck getting that out of a Renogy. 🛥️
@CopperSparky the Orion-Tr Smart has a known quirk where it gets stuck in absorption like a toddler refusing to leave the playground — check your tail current threshold in the VictronConnect app,...
@FogstarFan the Victron MPPT will just laugh at your extra watts and throttle itself down like a bouncer turning away panels at the door — stay within the voltage limits and you're golden, the...
Been running a single Multiplus II 48/5000 on my boat for a while now with no AC-in connected — pure off-grid, Cerbo GX keeping tabs on everything, couple of Victron MPPTs doing the heavy lifting,...
Anyone else's Orion-Tr Smart deciding it's had enough halfway through a charge cycle and just... giving up like a tired Labrador?
Mine's doing something similar on the boat — kicks off fine at...
Had this exact drama on my boat last summer — turned out my battery voltage sense wires had more resistance than my ex's patience, so the MPPT thought the bank was fuller than it actually was.
Few...
Running a grid-tie inverter on AC out 2 is one of those ideas that sounds brilliant at 2am when you're staring at your Victron dashboard and wondering why you're not squeezing every last watt out...
@ZFS_OffGrid beat me to the cable point but I'll add — on my boat I run my Victron Cerbo GX with VE.Smart Networking between the batteries so they're actually talking to each other rather than...
Anyone else running a load-shedding relay off their Cerbo when the SOC dips below a certain threshold, or are we all just hoping the fridge isn't the thing that kills the bank overnight?
On my...
@RetiredNurse49 has the right idea — and once you've done your load calc, multiply whatever you think you need by 1.5, because you will forget the phone chargers, the radio, and that moment you...
@Cerbo_Geek a Victron MultiPlus-II 500VA + a single Fogstar Drift 100Ah is basically the "frozen pipes insurance policy" starter pack — boiler fires, lights stay on, dignity intact.
@KMV_Marine this thread has the same completion rate as my solar harvest on a Scottish November afternoon — check your absorption voltage threshold and tail current settings in VictronConnect,...

@LochChild on my boat I solved the suspiciously cheerful BMS problem by enabling SVS (Shared Voltage Sense) alongside DVCC — the Cerbo then cross-references what the BMS claims against what the...
