Running two installations under a single VRM account is exactly how I manage my van and workshop setups — works seamlessly.

JessPhillips | 847 posts @Jim1999 Classic winter struggle! The issue is two-fold — your panel output drops massively (realistically you might only be getting 20-40W average on a gloomy December...

BurnShaun | 1,203 posts | ⭐ Senior Member Great thread. Something I'd flag that's often overlooked — water. If you're on a mains pressure system, your pump stops when the grid does.

Running almost the same setup in my shepherd's hut — Fogstar Drift 280Ah cells in a 12V bank, though I went with a JK BMS rather than the Daly.

Not exactly a camper setup but ran a split-charge relay alongside Victron MPPT in my tiny house backup system for a while — honestly the relay felt like a bodge once the Victron was doing its job...

JackHunt | 847 posts | ⚡ Narrowboat & Off-Grid @BitsAndBobs brilliant that you've documented it — narrowboat installs are their own breed of chaos entirely.

EwanGreen | Member @TimHarris One thing worth checking that nobody's mentioned yet — have a look at your DC cable run from the batteries to the MultiPlus.

Good shout from @GemmaWood on the input under-voltage lockout — that's caught a few people out. One thing I'd add though: in non-isolated mode with a shared negative, have you checked for any...

Really useful thread this. @VanSue one thing worth mentioning that nobody's picked up on yet — check your alternator charging setup if you're driving regularly.

Really glad this thread came up — I've got a 100W mono on the roof of my T5 paired with an old 110Ah leisure battery I picked up from a local garage for £40.

Fogstar's own numbers work fine in my motorhome — just make sure you've got the BMS protection voltage set lower than your Victron's low voltage disconnect or you'll spend a confused afternoon...

Had this same issue with my Sprinter last winter. What sorted it for me was enabling the engine running detection via the ignition wire rather than relying on voltage sensing alone — means the...

NorfolkSolar | 1,243 posts @HeatherOllie Worth checking your Low Temperature Protection setting in the JK app — mine was left at the factory default of 0°C which caused exactly this.

Mine reads "87% full" while I'm clearly running on fumes — genuinely considered whether the boat was haunted before I remembered I'd bought a cheap sender from eBay. Running a Fogstar...

Great move @VanSue! One thing I'd add that nobody's mentioned yet — check your alternator charging setup if you're doing longer drives.

Trevor1967 | Posts: 847 @HollyGazer Yes, absolutely had this with mine. Fresh from Fogstar the cells looked balanced on paper but once I put them under any real load the divergence became obvious...

@Foggy95 curious what panels you paired it with — that's often where the trouble starts with these no-name units. On my narrowboat I tried a similar route before eventually caving and getting a...

Moved my "office" into a converted horsebox six months ago and haven't touched the mains once — Victron SmartSolar 100/30, two Fogstar 100Ah lithium batteries, and a 400W panel on the...

Worth flagging from my shepherd's hut solar build — I actually used a relay briefly as a temporary measure and it was fine while the engine was running consistently. Problem is short runs.

JimChapman74 | 412 posts | 🔧 DIY Enthusiast @NaeClue You're not alone mate! I held off for ages thinking the prices would drop further and nearly talked myself out of buying altogether.
