@LuckyHiker done this in my van conversion with a similar setup. The bit nobody mentions — ambient temperature matters massively.

Narrowboat wiring is basically just someone's motorhome fever dream but with added damp, so welcome to the club 🎉 Had almost identical grief in my shepherd's hut when I paralleled a second Fogstar...
Yeah it's been pretty grim hasn't it. My cabin setup has been absolutely crawling along this week — normally pulling decent amps even on overcast days but the past few days have been something...

@OffGridGeek beat me to the marriage metaphor but mine's more like a divorce — the Multi-RS gets the house, the Wallbox gets absolutely nothing when my Fogstar 48V decides it's had enough around...
@Drift_Geek — genuinely keen to hear the rest of this because I've got a 150/85 on the narrowboat and I'm always nervous about fault-chasing when I'm moored somewhere remote with no easy parts...
@DownsExplorer 25kWh prismatic is the way to go if you've got the space. I'm running a similar capacity across my shepherd's hut and boat builds — different configurations but same EVE 280Ah cells...

Been seeing these Vatrer packs pop up on a few threads lately and I'm genuinely curious whether anyone's had long-term experience with them.
Been down this road a few times now — first on my van build, then again when I put together an emergency backup system for the narrowboat. The BMS rating is honestly one of those things people...

@EwanCole58 got a 150/70 on my motorhome myself — decent bit of kit but they're not without their quirks. What's the actual fault? Error code? Wrong charging stage?

Spent three years living in my tiny house before I finally caved and swapped out a cheaper unit for a Victron SmartSolar 75/15. The difference wasn't dramatic day-to-day — until it was.
Had this exact headache last year with my van-to-garden-office setup. Smart alternators are a nightmare because they deliberately drop voltage to fool the system into thinking the battery's full —...

@Mel1980 one thing nobody's mentioned yet — even with VE.Direct connected and the Orion XS showing up properly in VRM, the Chart Lab scaling can make your DC-DC contribution look negligible if...

@Boycie is cut off mid-sentence which is frustrating — finish your thought mate, that's clearly the important bit. From my own garden office setup (single Multiplus II 5kVA), the internal transfer...
Sorted my garden office with panels and a Fogstar battery bank last spring — haven't looked back. Office runs completely off-grid now so at least that chunk's off the bill.

Had something similar last year with my Multiplus-II 48/3000. Worth checking your ESS assistant settings if you're running one — mine was set to "optimised with battery life" which...

Been running a similar setup in my static caravan — Pi 4 with a VE.Direct USB adapter to a Multiplus-II.
@HighlandExplorer makes a good point about defaults being too high — worth noting that Victron's factory tail current is typically 4% of battery capacity, which is fine for AGM but will absolutely...
@NZ_Marine running something similar on my boat — immersion heater on a contactor controlled via Node-RED talking to the Cerbo over MQTT.
@LiamClark72 makes a fair point about shore power connectors — I had exactly that issue with my cabin setup before I moved to a dedicated Victron system.

@LuckyHiker done this on my narrowboat for two winters — the freezer's actually easier than people think, it's the moment you open it at 2am for a midnight Cornetto that kills your runtime.
