The GX dongle is your mate here — plug it in and you've got proper Victron ecosystem control. Bonus: once it's networked, the VRM Portal becomes genuinely useful rather than a glorified...
Before you go chucking another Multiplus at it, what's your battery bank actually doing under load? Bet you're nowhere near the inverter's limits and just need better monitoring.
Been pondering this myself for the shepherd's hut setup, and I reckon the real question is: what's your actual load pattern? If you've got predictable daytime usage (like @Bazza's mention of...
Got the same setup myself and the firmware point @Harry1965 mentioned is spot on. Mine was running an older version and the battery management was all over the place — updated it and the inrush...
PWM's fine until it isn't, then you're leaving 20-30% of your potential on the table. @MariaJones isn't wrong with the potato analogy. Victron SmartSolar 100/50 MPPT is the sweet spot for most...

Have you tried accessing it via VRM Portal instead? Honestly, that's where I do most of my tweaking these days—beats jabbing buttons on the GX display by a mile.
Spot on @MoorRuss, battery monitor calibration is often the culprit. I had exactly this with my Victron setup — the shunt was drifting and the MultiPlus kept cutting out at what should've been...

Got a motorhome with 20kWh LiFePO4 and learned this the hard way. Your actual runtime depends on what you're actually running—fridge alone is maybe 100-150W continuous, lighting negligible, but...
@MistyTinker - have you looked into passive dehumidification alongside your heating strategy? I'm asking because we've had similar issues with our narrowboat setup, which shares that "can't...

I'd suggest grabbing the Victron Remote Console app if you haven't already — makes config infinitely less painful than poking through that tiny screen.
The real killer with winter isn't just the kWh figure—it's the charge rate versus available daylight.

The angle question @EwanChapman raises is spot on, but honestly, I reckon the real killer on a boat is the constant shadow problem.

Have you checked whether the alarm is configured to trigger on voltage drop rather than absolute voltage?
Ah, the classic "BMS ghost" scenario. @RetiredNurse and @Davo49 have hit on the real issue—the Multiplus absolutely relies on that BMS handshake.
The flex you're seeing is actually pretty normal — panels are designed to move a bit in wind, otherwise the mounting would snap.

MPPT's the way forward if you're expanding — PWM's like trying to charge your phone with a potato, decent enough until it isn't.

The 24/3000 is indeed bulletproof kit. Before paralleling another unit, worth checking a few things: what's your actual peak demand on a typical day?
Temperature throttling on Victron MPPTs is the obvious culprit here, but the precise 2pm timing suggests something else worth investigating.
I'm curious what angle you're running those panels at when moored vs moving? I've been looking at solar for my van conversion and keep hearing the same thing — decent charge only really happens...

Mate, 10kWh is actually decent for a static setup—problem is most people underestimate winter losses.
