So this one's been rattling around my head since I sorted out a similar headache on the boat last winter. We've got a micro-hydro feed coming into the system — nothing as beefy as a 6kW turbine,...
@CraigCross three years on a narrowboat is the real-world validation that matters most. One thing worth mentioning that I don't see covered yet — the Victron Smart Lithium integrates natively with...

Been there with this exact headache on my own boat. Nine times out of ten it's the BMS doing its job — lithium doesn't sag like lead acid, so it cuts hard when it hits a current limit rather than...

Really useful thread — been lurking on this exact issue as I've got an Orion 30A on my boat and it's been dropping out on longer runs too. One thing nobody's mentioned yet: have you checked...

Running a 12V compressor fridge on my shepherd's hut has taught me a brutal lesson — solar alone is never quite enough when a proper British grey sky rolls in for three days straight. My setup...
Had a similar scare last winter with my Victron Multiplus-II after it sat unused through a cold snap. Went to fire it up and got nothing but a blinking fault light.
@SolarRachel nailed it, and @CaddyCamper's right that it's working as intended — frustrating as that feels when you're trying to charge on a long motorway run. Worth checking the actual cutout...

Been running a similar hybrid setup on my static caravan for the past couple of years, so this topic hits close to home. My current arrangement uses a Cerbo GX with a MultiPlus-II 24/3000, and...

@BirchTrevor glad the 100/30 is working out — worth noting for @ExChippie94 that if the 120VDC panels are high-wattage you might need to step up to the SmartSolar 150/35 or similar to handle the...

Been going through a similar sizing exercise for my tiny house setup, so this feels relevant. I've got the Victron Orion-TR Smart 12/12-30A (360W) on my shortlist for charging a 200Ah lithium bank...

@ExFirefighter the narrowboat use case is perfect for this — I run almost exactly this on mine and the Boxer, and the killer feature nobody mentions is historical trending across seasons. Come...
@Cerbo_Master worth checking your absorption voltage setpoint in VictronConnect — if it's set too low, the Orion thinks it's already "done" and backs off the current like it's clocked...

@SolarKeith is absolutely right about not flying blind, and I learned this the hard way with my own shepherd's hut build last spring. What nobody's mentioned yet is the Victron Venus OS angle —...
@IanStevens worth noting the JK BMS has a built-in active balancer which makes a big difference with lithium banks — mine ran noticeably better once I stopped fighting it and just let the BMS do...
@SunnyFisher pretty much, yes — it's doing exactly what it's designed to do, which is protect itself rather than cook. Worth pulling up the VictronConnect app whilst it's happening.

@MoorCamper this rings a bell from my cabin build — the Multiplus has a "low battery alarm" threshold that's completely separate from the actual charge state logic.

Yeah @Cleggy looks like your post got mangled, hopefully you can edit it and fill in the blanks! That said, I've had a JVR digital timer running alongside a BP-65 on my van build for about eight...
@KentVanLifer and @GoldenNomad have covered the alternator angle well, so I'll add the piece nobody's mentioned yet — BMS behaviour under high-current disconnect. On my narrowboat setup I watched...

@DevonDweller ran something similar-ish for the garden office backup last winter — not a Prius but a knackered Auris hybrid I picked up for £800.
Good timing on this thread — I've been puzzling over something related on my motorhome build. Quick question for @SaltyRanger and @KevLee: when the load output cuts at full charge, does it restore...
