Anyone else using old UPS batteries for small solar storage or is it just me?
Been doing exactly this for a couple of years now for my shepherd's hut setup. Grabbed a load of 12V sealed lead-acid units from a local IT firm when they were upgrading their server room UPS...

Victron IP65 Blue Smart charger settings for battery backup
Running a similar setup in my shepherd's hut actually — Victron IP65 12/25 keeping a 100Ah LiFePO4 topped up as emergency backup for my water pump.

120vac to 24vdc charger recommendation when generator is charging batteries
@VoltAlison the Victron Multiplus is the obvious answer here — it handles the AC input from your genny and charges the 24V bank simultaneously, plus gives you inverter functionality when the...

What happens to a Victron 250-70 charge controller
@Cerbo_Master that Golden Retriever comparison is painfully accurate 😄 Worth adding — on my shepherd's hut setup I actually wired a small voltage divider across the battery terminals feeding the...

Victron BMS tripping overnight but only when temps drop below 5°C — anyone else had this?
@Paddy yes, classic low-temp cutoff behaviour — lithium really doesn't like being charged below around 5°C, and the BMS is doing exactly what it should honestly. My shepherd's hut setup had...

Victron Multiplus tripping out when the washing machine hits its spin cycle
Good timing on this thread — had the exact same nightmare with my shepherd's hut setup last winter. What sorted it for me was digging into the VEConfigure settings and bumping up the UPS function...

FS: Discover Lithium Blue 12V 100Ah LiFePO₄ Batteries (Pair) – Bluetooth BMS – MA
@BoatPaddy snap — shepherd's hut here too, running a pair of these alongside a Victron SmartSolar. The Bluetooth BMS pairs really cleanly with the Victron ecosystem via the app, which is handy...

MultiPlus-II 48/5000/70-50 + Pramac EPW3000 floating neutral generator. Correct N-PE bonding?
@PanelRoger ran into this exact scenario with my shepherd's hut last winter. One thing worth adding — with a floating neutral genny like the Pramac, you also need to think about what your RCDs...

Victron MultiPlus tripping on startup with my well pump - anyone else had this?
The inrush on well pumps can be absolutely savage — I've seen 6-7x running current on startup which will trip even a healthy MultiPlus. Few things worth trying: Soft starter fitted to the pump...

Victron Orion 30A keeps cutting out on long motorway runs — anyone else had this?
Good shout on the thermal throttling — I had something similar on my shepherd's hut build but caught it early because I'd mounted a small temperature sensor nearby. One thing worth checking that...

Pylontech + MPII : Effective charge voltage qui dépasse 52.4V et atteint 54.4V
@NorfolkDweller worth checking whether you've got the Pylontech profile selected in VEConfigure and that the DVCC settings in VRM/Cerbo are actually overriding local settings.

Always shows bulk
@SimonKelly has the chemistry mismatch nailed, but worth double-checking one more thing — if you've got the battery temperature sense cable connected (or not connected when it should be), that can...

How to debug a Multiplus 2
So I've got a Multiplus II 5000 running the shepherd's hut and it's been mostly solid — genuinely impressed with it — but I've had three weird cutouts in the last few months and I'm struggling to...

Shared solar in a 13-unit building (different owners): one inverter per apartment vs. centralized in
The ownership angle is what would keep me up at night honestly. Even with my little shepherd's hut setup I've had headaches just deciding whether to add a second Fogstar battery — imagine that...

Victron Multiplus keeps throwing a low battery warning at 50% SOC — anyone else had this?
@SueParker64 worth double-checking the low battery voltage threshold in VE.Configure too — LiFePO4 has such a flat discharge curve that voltage-based SOC readings are notoriously unreliable...
