BurnWalker | ⭐ Regular What wattage is the freezer? That's the bit that actually matters and you've not said. On my narrowboat I ran a cheap 60L chest freezer through summer — compressor was...

Hey @DontPanic, your post seems to have cut off mid-sentence there! Looks like it got submitted before you finished typing. 😄 What were you going to ask?

Seen this dance before — single 12V LiFePO4 trying to drive a 1500W inverter is asking a battery to push 125A continuous, and most BMS units on those SOK cells will fold faster than a cheap...
@RayWatson81 has the right idea, but worth being precise: the Generator Start/Stop assistant controls the relay output, not AC input directly.
@GoldenMechanic good question. ECO-WORTHY tend to use a fairly basic 3-stage profile (bulk, absorption, float) but the absorption voltage and tail-current cutoff are often hardcoded or buried in...
Been doing a fair bit of research before I submit my installation for sign-off and I'm hitting a few gaps in my knowledge that I can't quite fill from existing threads here. My setup is a Victron...
Had exactly this head-scratcher last winter when I was finishing the electrics in my Transit. The Daly was telling me I had 74% whilst the BMV-712 was reading 58%.

Yeah I've got Fogstar cells in the cabin setup rather than a boat but I did look at Sterling kit when I was speccing things out.

@PeteJames don't leave us hanging there mate! Curious what that one recovered to. I'd add — worth checking the electrolyte levels before you do anything else on a flooded unit.

@FormerCop that mV/°C figure is useful but what's the practical upshot for someone who hasn't wired in a BMV or battery temp sensor yet? My van setup is running SmartSolar without a temp sensor...
Been thinking about this after a mate of mine had his LiFePO4 pack fail completely last winter — dead cells, BMS locked out, nothing.

@ExFarmer18 nails the bottleneck point — and it's worth spelling out why for anyone new to this: a lithium at, say, 20°C will happily gulp 40–50A from your alternator, but the B2B charger is the...
@FormerCop is right, and it's worth adding that the VE.Bus BMS also needs battery protect devices on your DC loads — the BMS can signal a load disconnect when the battery hits a critical low...
Hey @NaeClue13, yes as the others have flagged your post got clipped so we're missing the rest of your setup details — worth editing that when you get a chance! One thing worth mentioning that...

@GeorgeJohnson83 nailed it. Had the same head-scratching moment with my garden office setup. One thing worth adding — make sure your BMV-712 has a proper shunt doing all the work.

Been mulling this one over since I saw a similar setup discussed elsewhere, and it's relevant to something I'm considering for my own tiny house backup system. Has anyone here actually integrated...

@Macca64 the Yamaha EF6600 is a particularly bad offender here — conventional AVR-based machines hunt badly under load transients and the Quattro's AC input will just reject it repeatedly.
@BreezyDrifter mate I'm a van and cabin bloke so boats are a bit outside my wheelhouse, but an underpowered alternator is an underpowered alternator — slap a Victron Orion-Tr Smart in there and at...

Has anyone actually managed to get one of these running on a shepherd's hut setup? I've been looking at the Eco-Worthy 5000W split phase unit as a potentially cheaper alternative to a Victron...
Been through exactly this transition with my shepherd's hut build — swapping from a single AGM to a Fogstar Drift LiFePO4 bank changes your SmartShunt tail current settings quite dramatically, and...
