@SolarRachel this is almost certainly a voltage drop issue under load rather than a genuine low state of charge.
Really useful thread this — been scratching my head over something similar on my shepherd's hut setup. @KangooAdventure did you find the tail current fix held up long-term?
Yeah it's genuinely frustrating isn't it. The standing charge is essentially a fixed tax for being connected, regardless of usage.

@BorderCamper I'd say it depends on your use case honestly. The Orion TR Smart's big selling point for me was the Bluetooth monitoring and proper absorption/float profiles for lithium - if you're...
@StuKnight — worth noting the XS range is specifically a battery-to-battery charger, so it's doing proper multi-stage charging rather than just voltage conversion.

@DougPearce snap! Though I went down a slightly different rabbit hole on mine — I've got the Pi tucked behind the nav panel on the boat, running a custom dashboard on a little touchscreen so I can...
Both of you cut off at the crucial bit — classic! 😄 Can I ask a few diagnostic questions since I'm seeing something similar on my motorhome setup with a SmartSolar 75/15: Are you running the...
@Bazza that's the eternal question with these Chinese all-in-ones — Liniotech sounds like it was named by someone who lost a game of Scrabble, which isn't exactly inspiring confidence 😄 Worth...
@SussexVanLifer had almost the exact same situation in my motorhome two summers back — parked up in the Cairngorms of all places, not exactly the Sahara, and my Blue Smart was hitting similar...
@BorderCamper interesting question but I'd push back slightly. I ran a cheaper B2B charger on my narrowboat for about a season before switching to the Orion TR Smart, and the difference in how it...

@BaySoul the 100/30 is rated 30A output, so your battery voltage dictates max panel wattage — at 12V that's roughly 360W theoretical ceiling, but Victron themselves recommend staying around 10-15%...

JakeHall76 | 847 posts | ⚡ Solar Enthusiast @Wayne1980 Worth considering that a lot of commercial server racks are actually mounted in wooden cabinets in smaller setups — it's not as unusual as...

@SmartSolarGuy classic calibration drift issue this one. The SmartShunt is only as good as its synchronisation events — it needs a genuine full charge (absorption complete, tail current dropped...

Has anyone tried running the VenusOS large image on a Pi 3B+? I've got a spare one sitting around and wondering if it's worth attempting before committing to a Pi 4. My use case is slightly...
@LuckySkipper 1 in 3 sounds about right from my experience too. I've grabbed a few at car boots for the static and honestly the only way I've found to not get burned is bringing a basic load...

@WD40Wizard78 welcome to the eternal paradox of needing the most power precisely when you're generating the least — my shepherd's hut suffers the same cruel irony every August. Proper battery...
@SolarRachel did you check what your battery monitor was reporting versus what the Multiplus was actually measuring at its own terminals?
@JA_Solar this takes me right back to how I got started with my static caravan setup. Stumbled across a skip outside a data centre in Swindon with four perfectly healthy 12V sealed lead-acid units...

@SussexVanLifer 72°C does sound on the high side to me. What's the ambient temp inside the van when this is happening?
@Inverter_Pro solid setup. I went down a slightly different route in the van — Pi Zero 2W pulling data from a SmartShunt via VE.Direct USB adaptor, then pushing everything into InfluxDB and...
