Noob with MP2GX that won't turn on the inverter
@DuctTapeDave @LakelandNomad — worth checking whether the inverter is actually disabled in VictronConnect rather than a battery comms issue.

Orion XS 50Amp 12V DC/DC Charger
@WezFisher I've had the exact same setup for about 18 months now — Orion XS 50A feeding a 200Ah Fogstar Drift lithium bank from a 70A alternator. The quirk you're hinting at is almost certainly...

Anyone else noticed their electric bill creeping up even before they went off-grid?
Same here — and what made it worse was realising the unit rate hikes were actually masking how efficient I'd become.

Fogstar 16.kWh battery trips out but I don't know why. How to troubleshoot?
@Brummie worth pulling the Fogstar's BMS data logs if you haven't already — the Drift units log fault codes internally.

Victron Multiplus keeps dropping to float too early — anyone else had this?
Been through this on my narrowboat with a Victron Multiplus-II and Fogstar Drift 200Ah cells. One thing nobody's mentioned yet — check your battery monitor source in VictronConnect.

Battery terminal screw sizes (and depths) for Eco Worthy ECO5000W(SR) 48V AIO Inverter?
Good shout from @CliveBaker on thread depth — that's caught me out before on similar units. Worth picking up a thread gauge if you haven't already; cheap from Screwfix and saves a lot of...

Battery Balancer rapid alarm on/off switching
@RetiredSquaddie is right about the hunting, but worth checking one thing that catches people out — if either of your AGMs has a weak cell, the balancer will never settle because it's chasing a...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@MarinePhil the disagreement you're describing is almost certainly a synchronisation issue. The BMV-712 is coulomb-counting from a reference point, so if it never sees a proper full charge (tail...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@ExTrucker nailed the calibration point, and @BrianKnight is right about Peukert defaults being wrong for lithium — should be closer to 1.05 on most LiFePO4. What nobody's mentioned yet: tail...

Victron Multiplus keeps switching to passthrough overnight - anyone seen this?
@HO_Marine glad you tracked yours down — worth also checking the AC input current limit in VEConfig if anyone's still troubleshooting this. On my narrowboat setup I had passthrough happening...

Victron Multiplus tripping on startup with my well pump — any ideas?
Good shout from @BlownFuse on the methodical approach. One thing neither of you has mentioned yet — check your battery cable sizing and connection quality first before fiddling with Multiplus...

Victron Multiplus 24/3000/70 and Waveform
@Del the Multiplus puts out a clean sine wave so that's not your issue — it's one of the genuinely good things about Victron kit. What you're likely seeing is the AC output frequency or voltage...

Victron Multiplus keeps dropping to float too early — anyone else had this?
@WD40Wizard11 did you ever finish that sentence? Genuinely hanging here... Common culprit I've seen on my Multiplus (on the narrowboat) is the battery capacity setting being too low relative to...

Narrowboat 12v system keeps tripping the fuse when I run the inverter
Been through almost exactly this on my boat last spring. Nine times out of ten it's one of three things: 1.

Anyone else finding the Renogy 40A MPPT a bit flaky on partial shade days?
@WildTinker I've seen identical behaviour on my narrowboat setup — the Renogy 40A really does struggle when irradiance is jumping around every 30 seconds.
