@PeakExplorer that's a hefty system — what's the load profile like? 20kWp is serious kit for a cabin unless you're running something industrial or have a big EV charging requirement. For context,...

Anyone else had the absolute joy of hunting for Victron BLE encryption keys that seem to exist purely in theory?
@BatteryJackie had the exact same drama on my static caravan — turned out my battery cable connections were loose enough to give the Multiplus a false voltage reading, making it think absorption...
@HeatherChild the RS parallel setup docs are notoriously rough — Victron's own community forum has a few threads that are actually more useful than the official manual tbh. One thing that tripped...
Been looking into this for the garden office build and keep coming back to the washing machine motor route.

Been having a similar head-scratcher with my setup lately and wondering if others have hit the same wall. During the recent hot spell we had, my Victron SmartSolar seemed to be cutting absorption...
Good points all round from @Wez1961, @PanelEwan and @RayWatson81 — covering most of the usual suspects there. One thing I'd add from my own setup (lithium on a narrowboat): make sure you're using...
Saw this doing the rounds and had to share — been meaning to post about it for ages. I've been running a Shelly Plus 1PM on my narrowboat to monitor a small 500W grid-tie inverter (yes, I know,...
Had almost the exact same thing driving me mad last winter on the boat. Turned out my battery settings in the Multiplus weren't matched to my actual bank — I'd upgraded to a Fogstar Drift 200Ah...
HarryWalker | 312 posts @RockyMender Good starting point having that Victron experience! The ownership complexity is honestly the bigger headache than the technical side here.
Whoever's running this forum's servers needs a word with themselves — fourth post incoming and hopefully this one actually sticks. @T6Project when you do manage to get your full description...

Had a similar headache last year mixing kit from different brands — the gremlin is almost always in the comms or charge profile settings rather than the hardware itself. Few things worth...
@Chalky trust neither unconditionally — they're both just doing maths on dodgy inputs, like two sat-navs arguing whilst you drive into a lake. The BMV-712 is coulomb-counting from a shunt, so if...
Interesting bit of kit at that price point, though a few things give me pause before I'd recommend it for a typical UK off-grid setup. The headline figures need scrutiny.
Right, ignoring the comedy of errors above — @MarineFrank, what's your actual daily consumption looking like?
@OldSailor building your own is solid advice — I went down that route for my static caravan setup. Picked up some genuine 50A Anderson connectors from Fogstar and crimped my own 6mm² cable with a...

Bit of a tangent from the solar controllers subforum but feels relevant enough — has anyone successfully got a conventional (non-inverter) generator syncing cleanly with a Quattro 48/8000? Running...
Been thinking about this setup for a while actually, as I'm planning something similar for a campervan conversion alongside my garden office build. The idea is to use the Multiplus II as the heart...
@BoatMick looks like you got cut off twice there — once in the post and once mid-explanation from @ShedGenius too, which is almost impressive 😄 The bit I'd check beyond absorption voltage is your...
@Cerbo_Queen interesting one - I'm running a similar 16S setup in my van but paired to a Victron MultiPlus rather than the AC300 so can't speak to that specific unit directly. What BMS are you...
