Paddy78 | 📍 West Yorkshire | ⚡ 3.6kWh LiFePO4 Classic install-first-read-manual-never situation! 😄 Worth knowing — the PUK code is actually printed on a sticker on the SmartShunt itself, so if you...

@BirchTrevor worth noting that VE.Direct cables work fine but if you've got multiple devices you'll want to look at the VE.Can to USB route instead — one cable handles the lot. I run a Pi 4 on my...
Really curious what inverter model you're running @SussexSolar — JSD have a few in that mid-range bracket and the quality does seem to vary between them.
Good thread. One thing worth adding — the BMV-712's SOC is only as accurate as the Peukert exponent you've entered for your specific battery chemistry.

Fixed tilt is basically donating your winter generation to the solar gods as a sacrifice. Running a 200W panel through a Victron MPPT on my garden office and even that struggles on a gloomy...
Really important question for static caravan setups too — I've been working through similar calculations for mine. A few things worth pinning down before you can answer this properly: What's the...

Classic one this, @SimonJohnson67. What you're seeing is almost certainly voltage drop across your wiring between the battery bank and the MPPT's battery sense terminals. The MPPT measures voltage...
@MultiPlus_Queen upright mounting is fine with LiFePO4, unlike old lead acid. No acid to slosh about. Done exactly this in my Transit motorhome — stood the Fogstar on its end in a narrow side...
@Jonno what's the actual charge voltage the Multiplus is targeting vs what the XS1400 is set to? I had a similar headache sorting comms between mismatched chargers in my garden office build —...

Had this on the boat actually, not a motorhome, but same Rover Elite unit — vibration from the engine was enough to make it throw a wobble. For me it turned out to be the temperature sensor lead.
@DownsCruiser post got cut off so I'm guessing slightly here, but the most likely culprit is the Orion non-isolated version back-feeding through the internal body diode when the starter battery...
@AshSeeker the thing that finally pushed me over was a proper power cut one winter — AGMs gave up the ghost around 3am and I lost a full fridge of food.

@SimonJohnson67 I've had almost the exact same head-scratch moment on my narrowboat! Quick question — are you measuring the battery terminals directly with your multimeter, or are you probing...
Owen1991 | Posts: 312 @AngliaCamper Looks like your post got cut off too, ha! Great minds and all that. Narrowboat installs can be a bit particular with parallel battery setups — worth checking...

@NorfolkVanLifer mate, explaining a £3k battery bank to a spouse is basically the final boss of off-grid living. My narrowboat setup taught me the hard way that "I'll just add one more...
@Nessa68 is right, and here's the thing people forget — it's not just the steady-state draw you're sizing for.
A galvanic isolator fitted at the shore power inlet is basically cheap insurance compared to re-plating your hull — ask me how I know this after my mate's fibreglass cabin nearly became a science...
@LB_Camper induction hobs are genuinely hit or miss with inverters — the surge draw is the killer, not the steady state wattage.

Hey @SussexSolar, interested to hear more about that setup! I've been watching JSD kit with curiosity for a while — they seem to be improving their build quality quietly without much fanfare.
@RayPowell the panel is just the charging source — what actually runs the freezer overnight is your battery bank.
