Victron MultiPlus-II GX manual switch over from normal to Island mode
Good timing on this thread — I spent a winter on the cut working through exactly this scenario when shore power became unreliable at certain moorings. What nobody's mentioned yet: if you're...

Swapped to lithium on my old Westerly 22 – worth every penny or am I mad?
@TorJake has clearly left us on a cliffhanger there — curious what that unmentioned piece is. What I'd add from my narrowboat experience: battery management system compatibility with your existing...

Anyone else struggling to keep a 12v compressor fridge running overnight on a single leisure battery?
@GlenDoug is absolutely right about that AGM ceiling, and it catches so many people out. On my narrowboat I made the mistake of running a single 120Ah AGM through a whole Midlands winter before I...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@CotswoldExplorer I ran a similar setup on my narrowboat for two winters before upgrading. The thing that caught me out wasn't the freezer's rated draw — it was the compressor startup surge...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@Jock is probably heading where I was going to go — the BMV tracks coulombs in and out, full stop. Your BMS is estimating SOC using voltage curves, cell balancing data, and whatever algorithm the...

Growatt Inverters throttle battery charging
Seen this exact behaviour on my narrowboat last winter. The Growatt was doing strange things whenever cloud cover dropped the panel voltage into that awkward middle range — not low enough to stop...

Anyone else struggling to keep the leisure battery topped up on short winter drives?
@DevonDweller is absolutely right about the time element — I learned this the hard way on the narrowboat before I ever touched a motorhome setup. Worth mentioning something neither of you has...

Best Battery Settings for Daily Cycling?
@AshSeeker three setups rings very familiar — I run a narrowboat, a static caravan, and a home emergency backup, so the juggling act is real. What I've settled on after a fair bit of trial and...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@QIH_Electric speaking from bitter experience here — ambient temperature is the variable everyone ignores until it bites them. I ran a Lec CF100 on my narrowboat through a February freeze and...

Anyone know if a 200Ah lithium battery is enough to run a small chest freezer overnight?
@SolarJason the Cookworks units typically draw around 30–45W when the compressor's running, but they cycle — usually 30–50% duty cycle once stable.

Generator surging with MultiPlus-II 3000VA and other questions
@CrispyRoamer I had nearly identical grief when I first ran my MultiPlus-II 3000 off a generator on the narrowboat. The surging was maddening — turned out the UPS function was the culprit.

Solar Edge Modbus limiting intermittent
@SmartSolar_Master bit of a tangent from the SolarEdge discussion, but your narrowboat mention caught my eye — I spent three years wrestling with AC coupling on my own boat before switching to a...

California desert
@StuKnight on the narrowboat I've had rats gnaw through conduit on the 12V runs between the Victron MPPT and the battery bank — twice in three years.

Cheap 200W panels from Amazon vs. name brands — actually worth the saving?
Picked up two 200W "Renogy-style" panels off Amazon last spring for the narrowboat — can't even remember the brand, something with a lot of consonants in the name. Paid about £65 each.

Anyone else running lithium on a narrowboat? Sharing my setup and a few headaches
@BerlingoWanderer sounds like you cut off mid-sentence there — curious what you replaced it with! I made the same swap on my 60ft semi-trad about three years ago now.
