Anyone else using a small inverter generator as emergency backup alongside their solar setup?
ZFS_OffGrid | Posts: 213 Got a Jackery 2000 Pro sat as buffer but yeah, small genny is the sensible belt-and-braces move.

Powering a garden office with solar + LiFePO4 — is 200W/100Ah actually enough?
Depends entirely what you're running in there. 200W/100Ah is fine for laptop + lighting + phone charging.

Switched from AGM to lithium mid-build — here's what actually surprised me
@DriftGal same boat here, well, same van. Had AGMs in my old motorhome for years and the weight alone should've pushed me to lithium sooner.

Generator Oscillation during Charge
@George1975 classic Multiplus bulk charge chaos — seen it on my static and the motorhome both. Nine times out of ten it's the dynamic current limiter not being set right in VEConfigure.

Load Output configuration query on MPTT Solar Controller
Lol the server hamster's clearly on solar with a dodgy MPPT 😂 Anyway — load output on those Victron controllers is more useful than people give it credit for.

Stripped Neg (-) Battery Terminal Screw - SmartSolar 150/45 MPPT - how to salvage my mistake?
@CornishBoater is right on the M6. Few things worth trying before you go nuclear on it: Thread chaser first — might just be mangled not fully gone If it's properly stripped, a M6 stainless bolt...

Battery backup with SolArk or EG4 inverter and generator
Bit of a red flag for me tbh — SolArk and EG4 are designed around 120V split-phase US grid standards.

Avis sur installation auto conso 3kW avec batterie
@SolarKeith don't knock the Fogstar Drift, I've got two of them in my static and they've been solid for 18 months — touch wood. @Taffy the dual-use thing sounds clever until you're trying to lug...

Over charging
@Jock had similar grief with my AGM bank before I switched to lithium. The problem isn't just the peak voltage — it's duration.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@TorDweller done this on my static van. Real world numbers matter more than specs — chest freezers cycle on/off so actual overnight consumption is way lower than the rated wattage suggests. Stick...

ZYC 100ah 48v Lithium battery not reflect in victron Multiplus II GX.
@DailySolar is right about the BMS internals. Worth grabbing a cheap USB-to-UART cable and connecting directly to the BMS first — at least confirm it's actually alive and reporting correct cell...

Anyone else struggling to keep the leisure battery topped up on short winter drives?
@QuietMaker already covered the Orion so won't rehash that. Worth mentioning though — winter alternator output is genuinely poor on older vehicles. Cold, short runs, engine not fully warm...

ECO-WORTHY PowerMega 314, 48V 314Ah Lithium battery.
@SimonKelly yeah the cell sourcing is the real question isn't it. Could be decent CATL B-grade, could be something far sketchier.

Victron MPPT kept dropping connection overnight — faulty unit or just settings?
@CaddyProject had the same faff on my static last year. Before you chase the dongle rabbit hole though — check your VE.Direct cable first.

Victron BMV-712 showing different SOC to my BMS - which one do I trust?
@HollyGaz on the narrowboat — worth knowing that coulomb counting (what the BMV does) drifts over time without clean sync points.
