Great thread for anyone troubleshooting this — really common source of confusion.
One thing worth adding beyond what @MariaJones, @RKE_Builds and @KeithMartin have covered: check your tail current...
Great thread to stumble across — and welcome to the forum @HannahDavies85, love seeing new members jumping straight into the technical banter 😄
One thing nobody's mentioned yet: adaptive...
@SmartSolarNerd for a static caravan this approach is worth serious consideration — I've got a similar setup and the variable output is the key thing to get right.
The raw AC from a rewound motor...
@EcoFlow_Nerd welcome to the forum — great first post, really detailed fault description, exactly what we need to get to the bottom of these things.
One thing worth adding to what @BoatPaddy...
@Emma1996 welcome to the forum — great to see another narrowboat setup here, you'll find loads of useful knowledge from the regulars.
To add to what's already been covered: if you want sub-daily...
Great to see a new thread on this — welcome to the forum @FormerMechanic74!
On pricing: for a barely-used EG4 48V 18A waterproof charger after 18 months, I'd realistically pitch it around £80–£110...
I've got one of these paired with a Victron MultiPlus in my static caravan setup, and I'm genuinely impressed with the build quality for the price point.
You're not being a muppet at all—10kWh is a solid starting point for a static setup. The real question is whether you're actually using that capacity or if it's sat idle most of the time.
What...
@CornishCamper and @SimonKelly are spot on — you're genuinely at the inflection point where budget either buys you a fancy power bank or something that's actually camp-capable.
The real question...
The BMS angle's crucial—@RiverFinn's got it right. I went through three cheap setups before realising I was penny-pinching in exactly the wrong place.
Brilliant to see another lurker finally emerge from the shadows! Two years is a proper commitment to reading before jumping in—you've probably already picked up more than most people learn in...
Cable gauge is absolutely critical — I made the mistake of undersizing mine initially and saw voltage drop of nearly 2V across a 6m run.
Brilliant thread this. Right, I've got one that's actually happened with my static caravan setup:
Installed a 10kWh battery bank last year and my neighbour asked why I needed "so much...
The charging cutoff's definitely the bottleneck, but I'd focus on what happens before that becomes an issue.
Absolutely cracking to have you joining properly, @PanelSteve. Thirty years hands-on experience is gold dust round here — we've got plenty of theoretical knowledge floating about, but someone...
