Had the 18A in my garden office setup for about 18 months — honestly it's been fine for a single 100Ah LiFePO4.

Running a Drift 100Ah in my garden office — same ballpark as what you're speccing.
@XJ_Solar portrait orientation saved me a surprising amount of space — worth trying if you've been defaulting to landscape.
@SolarJake the Multiplus-II has a built-in AC generator start/stop via its aux relay — worth digging into VEConfig if you haven't already.
Worth checking one more thing before swapping the dongle — the VE.Direct cable itself. Had this on my garden office setup last autumn, Victron SmartSolar 100/30, and the culprit was a slightly...
Had this exact headache with my garden office setup last year. The capacitor inrush is the bit that catches people out — the Multiplus will pull a surge when it first powers up and if the BMZ...
Classic surge problem. The Multiplus is rated for continuous load but washing machine motors can pull 3-5x their running watts on startup — your 3000VA unit might be seeing 6000W+ for that split...
@KenCross yeah the CSV export is a bit of a pain — it's daily aggregates only, not live samples. You're essentially getting peak power, yield kWh, and that's about it per day.
If you want proper...
@TorDweller should be fine honestly. Chest freezers are decent because they cycle on/off rather than running flat-out — realistically that 45W unit is probably averaging 15-25W over time once it's...
Just spotted this on the Humseink site and the pricing's mental — nearly 50% off is quite the deal for 16kWh LiFePO4.
Been down this rabbit hole myself, mate. Trying to track down proper documentation for integrated systems is a nightmare. Got a Victron setup with the GX display and the manual situation is...
Right, so I've got a cheap PWM sat gathering dust in my shed from when I first started messing about with solar. Absolute nightmare, honestly.
Ah mate, that's rough. Before you bin it, worth checking a few things:
Battery connectors — sounds daft but corrosion on the main terminals can kill it stone dead.
The real gotcha nobody's mentioned is grid interaction. If you're genuinely off-grid, you're limited by battery capacity and charge controller headroom.

Most motorhome breakers will take them for scrap lead — ring around your local ones first. If that draws a blank, your council tip takes them free.
