MuddyTinker | Posts: 134 | Location: Array Coming at this from a boat perspective so slightly different constraints, but the sizing question is the same headache.
Has anyone actually tried adjusting the low-temp charge protection thresholds via the Xiaoxiang BMS app?

Same boat here, though mine's a garden office rather than a van. I ran a generic 2000W pure sine inverter for about eight months before the monitoring gap drove me absolutely mad — you're...

@DODNerd classic JK moment — mine did exactly the same until I bumped the cell deviation threshold from the default 300mV down to... wait, no, up...

Running a Victron SmartSolar 100/30 with 400W of panels (two 200W Renogy monos in series) and I've been logging the data through VRM all this winter.

AlexPalmer60 | 203 posts Running a mixed array on my garden office setup — two 200W Renogy panels paired with an older 160W I had spare.

Really echoing what @FormerCop77 is hinting at — November through February is where UK solar really humbles you.

Good shout from @Hamish1980 on the connections — I'd add that it's worth checking the sense wire terminals on the cells themselves, not just at the BMS end.

VanKen | Posts: 156 | Location: Static caravan, somewhere damp My "backup system" is a £40 Lidl inverter generator, a Fogstar 100Ah I pretend is retired, and the quiet dignity of a man...

@EwanMurray done this twice now with EVE cells — once for the van, once for a cabin backup build. Top balancing is non-negotiable before first use.

@DODNerd — classic top-of-charge drama, that. Had exactly this with my shepherd's hut build last spring.

VoltGeek | 2,847 posts | West Yorkshire @ShedGenius79 Solid choice on the Fogstar Drift — cracking battery for the money.

MidlandsCamper | Posts: 2,156 @Trevor1967 The 30A Orion in absorption is only targeting ~14.4V by default — sounds like it's actually working correctly.

BordersExplorer | 1,204 posts One thing neither @RussThomas nor @EdGrant91 has touched on yet — pay close attention to your Voc and Isc figures across both panel generations, not just the wattage...

RhysGrant | 847 posts | Welsh Borders @PeakExplorer the XS 50A is a proper step up, particularly if you're planning any EV top-ups.

CraftyGrafter | 203 posts @TracyRobinson Snap! Though mine's a cheaper Aldi special rather than a Yamaha - does the job though.

@IanWhite I narrowboat rather than sail, but the swap from FLA to LiFePO4 is a tale I know well. The detail that catches people out — and I suspect may be lurking in your write-up — is resting...

WattAMess27 | 312 posts @GafferTapeKing19 Great setup! One thing worth mentioning that nobody's touched on yet - watch your panel angle through December and January.

@Brian1975 mapped mine on a Post-it note in a Tesco car park, turns out "kettle, laptop, occasionally the angle grinder" is not a load profile — it's a cry for help from my Victron BMV-712.
