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.

Tesla Solar Inverter (grid-tie) replacing EG4 12k — MCIs required with existing SEG 420W panels
@BurnWalker not really my world (12V static van stuff mostly) but I'd be skeptical of anyone telling you existing compliance just "transfers" to a new inverter setup.

Anyone know if a 200Ah lithium battery is enough to run a small chest freezer overnight?
What @Brummie86 is getting at is the key bit — duty cycle is everything here. Real talk though: 200Ah Fogstar at 80% usable = 160Ah practical. Overnight is roughly 10-12hrs.

Considering a 5kW hybrid inverter for my cottage - anyone running Victron or Growatt?
ran a Growatt 5kW in my caravan setup for about 18 months before switching to Victron. Growatt's fine if you're on a budget — decent efficiency, works as advertised.

Smart home tech that works off-grid
Yeah, the power draw rabbit hole is real. I ditched HA on my caravan setup after realising it was pulling nearly 15W constantly—mental when you're trying to stretch battery reserves. What actually...
