Thread title's in French but the question's universal — DC negative to PE only at one point (usually the MultiPlus chassis), not at the Lynx Power In itself, unless you fancy chasing gremlins...
Two MPPTs on the same array without proper load sharing is just two blokes arguing over the TV remote — someone's always losing.
The VE.Smart Networking on Victron gear does help them play nicely,...

@BayLisa been there — mounted mine in what I thought was a well-ventilated spot on the narrowboat, turned out I'd essentially built Victron a little...
@SolarRob spent three weeks arguing with myself about this on the narrowboat before a sparky mate just pointed at the Victron wiring unlimited guide and said "it's in there, mate" —...
Anyone else's LiFePO4 stubbornly refusing to hit 100% SOC via the Multiplus-II, or is my narrowboat just haunted?
Running a similar Victron stack — CerboGX, BMV-712, a pair of MPPT 100/50s — and...
Been running a Victron Orion-Tr Smart 12/12-30A on the narrowboat for about two years now, pulling from the engine alternator into a 200Ah Fogstar LiFePO4 bank — honestly it's the single best...
Running a 24/3000 as a temporary stand-in for a 24/5000 on my narrowboat taught me that the Fronius will absolutely throw a wobble if the frequency shifting headroom doesn't match up properly —...
Mate, the MAN TGE's smart alternator is basically a toddler having a tantrum — the Orion XS handles the mood swings beautifully once you nail the input voltage thresholds, had similar grief on the...
@BoatMick done exactly this on the narrowboat — thought 200Ah was generous until a cloudy British weekend reminded me that "seemed plenty on paper" is just the universe's way of setting...
@WonkyRigger been running a knackered old 20Ah AGM under the stern deck purely for the bilge pump and a cheap 12V lamp — basically my "well at least I won't drown in the dark" battery —...
@WhatsAFuse65 my narrowboat ran entirely on a cliffhanger once too — turned out I'd just forgotten to connect the negative terminal, so don't rule out user error before you've even told us what...
@Kingy74 Check your BMS discharge rate limit — JK units sometimes default to a current threshold that'll cause it to pull the plug faster than my ex-wife did, and the MultiPlus sees that as a dead...
Got a battered old Kipor sat in the engine bay of my narrowboat for exactly this — solar's great until November decides it wants to be Scotland for six weeks straight, then you're just staring at...
@DucatoBuild "essential" is doing some heavy lifting there mate — on my narrowboat I ripped the old VSR out the moment the Orion-Tr Smart was bedded in, never looked back, and the only...
@ForestDweller living this nightmare on my own boat — BMS said "nope" on a -3°C morning last January and left me with a very cold and very dark breakfast situation that no amount of...
