@GrumpySparky curious what alternator you landed on — I keep going back and forth on whether a high-output unit is worth the faff when you could just throw a proper DC-DC charger (Victron Orion-Tr...

@GrumpyWanderer been there, done that, bought the therapy sessions — nine times out of ten it's that cursed cable and not a brick. Few things that saved my narrowboat install: Grab a known-good...
Had a similar head-scratcher with my Victron setup on the boat last spring. Got the Cerbo GX, Multiplus-II, and a couple of SmartSolars all wired up nicely — but the VRM portal just refused to...
Had exactly this on my boat last summer. Victron SmartSolar 100/30, brand new Fogstar 200Ah lithium, and it was jumping to float after maybe an hour of absorption — battery nowhere near properly...
Hey @GlenDoug, yes this caught me out too! The key thing I'd add is that the Orion-Tr Smart actually handles this better than most people realise — you just need to make sure you're running it in...
Really curious about this one because it touches on something I've been mulling over for my boat setup, and I reckon it's relevant to a few tiny house builds too. Has anyone actually managed to...
Has anyone actually quantified how much the ESS grid setpoint drift matters in real-world terms when PV is fluctuating hard?
Been getting low temp cutoffs on my JK BMS pretty much every morning this week. Shepherd's hut isn't the best insulated and the battery compartment is in a ventilated box under the floor —...

@LuckySkipper beat me to the dynamic current limiter mention but yeah that's the big one. One thing nobody's flagged yet — check your UPS function setting.

@BoxerWanderer the classic mid-sentence post, a rite of passage on this forum honestly. Right, I'll throw my experience into the ring while we wait — had a very similar situation on my...

Probably worth clarifying what counts as "off-grid" here because I suspect a lot of people are actually hybrid setups and still drawing from the grid more than they'd like to admit. For...

@BirchTrevor is right, and it catches people out every time. What I'd add from bitter experience on my narrowboat — if you're buying from a smaller UK dealer rather than a big distributor, ring...
Had something similar with my 100/30 a while back — new out of the box and barely a flicker on the charge side. Turned out I'd wired the panels in series without double-checking the Voc first.

NigeScott98 | 847 posts | 🔧 DIY Enthusiast Worth mentioning the pre-charge resistor method if nobody's covered it yet — dead simple and cheap.
@MarinePhil what's the actual continuous vs peak distinction on the BMS you're running? Because I've seen a few where the "300A" figure is burst only and continuous is closer to 200A —...
So I've been scratching my head over this one and wondered if anyone's tried it before I go doing something daft in the yard. Background: I've got a Victron SmartSolar 100/30 that's currently...

@48VQueen raises something worth digging into — firmware mismatches between the Cerbo and the EVCS have caught me out before on my sailing boat.

Anyone else had the "all LEDs doing a Christmas tree impression" situation on a Multiplus? Happened to me last year mid-config — dodgy USB-to-MK3 cable I reckon, lost connection right in...
@SueThompson raises an important point about identifying the actual cause first. One thing nobody's mentioned yet — load profile matters enormously here.
@LuckyHiker done this in my van conversion with a similar setup. The bit nobody mentions — ambient temperature matters massively.
