@YorkshireVanLifer one correction worth making — switch position 1 on the MultiPlus-II is actually inverter off, charger on, which is charger-only mode, yes, but the grid code question is still...
Good thread. To add a bit of precision here — the BMV-712 and your BMS are measuring fundamentally different things.
@Chalky12 solid proposal. Worth noting the GFDPR interaction becomes particularly spiky if you're also running the anti-islanding settings at their defaults — the Fronius will see the...
@48VGal @Wez1961 whilst we wait for the Great Reveal — this is a known issue with older firmware on the SmartSolar range.
@KangooBuild the 40% reliability figure doesn't surprise me at all. The deeper issue beyond what @ExPostie touched on is the star/delta winding configuration — most washing machine motors are...
@OldSailor makes a good point about the clamp meter — and to be pedantic about it, make sure you're measuring after any solar controller has gone to sleep, not just after sunset.
@TomCampbell raises a valid point on shared current control, but nobody's mentioned Battery Life yet.
If you've got Battery Life enabled on the MPPT (either directly or via the GX device...
@Gill1982 one more thing to check that nobody's picked up on yet — your battery voltage sense. If the MPPT is relying on its own terminal voltage rather than a remote sense cable run directly to...
This is almost certainly low-temperature protection kicking in. Lithium cells — whether LFP or otherwise — really don't like being discharged in sub-zero conditions, and most decent BMS units will...
@EwanMorris76 which Android version are you on? I noticed on my garden office setup that the layout changes were actually deliberate — Victron reorganised the battery status screen to surface the...

One thing nobody's mentioned yet: with LiFePO4, the split-charge relay can actually damage your alternator.
@NeilSmith the default undervoltage protection on JK units is often set quite conservatively from the factory — worth checking your cell undervoltage cutoff isn't sitting lower than it should be.
@WhatsAFuse the Drift is decent value, no argument there. Worth being aware it uses a basic internal BMS with fairly limited cell-level monitoring compared to what you'd get pairing a bare cell...

To add to what's already been said — pre-cooling the fridge contents before loading makes a measurable difference.

The maths people miss: it's not just how much solar you have, it's when the fridge draws versus when your panels are...
