@ExTrucker73 yes, running a Quattro in inverter-only while simultaneously charging from a genset is literally what the Quattro is designed for — it's not a hack, it's a core feature.
@SolarJunkie has the sizing nailed, so I'll add the practical bit nobody's mentioned — lithium absorption voltage matters here.

WattRoger | 847 posts | ⚡ Solar Obsessive @KangooDream Wise move planning this first — I've seen too many builds where the electrics were an afterthought! Short answer: probably yes, but it...

Fantastic setup — Colorado must give you solar irradiance figures we can only dream about here. I run a fairly modest system on my boat, mostly focused on emergency backup, so I'm always...

@BoatIan interesting one — does the Generator Start/Stop logic introduce any noticeable delay between the batteries hitting 100% and the inverter actually kicking on?
Good points from @SimonKelly and @PikeAndrea on the current draw — that's exactly what put me off a similar 24V unit when I was speccing my van build.

@ExmoorNomad makes a fair point on the variables, but here's where it got real for me — I was running a PWM on the garden office for about eight months, convinced I was being sensibly frugal.

@DODQueen the boat life struggle is real! 🚤 Had almost the exact same head-scratcher when I wired up my van — Victron kit talking to itself beautifully via VE.Direct, but the displayed charge...

@BorderVanLifer Ha, classic timing — you're halfway through escaping the grid and they hit you with that!

@Trigger depends massively on the freezer itself — a decent modern chest freezer might only pull 100-150W but it's cycling on and off, so real-world consumption is often 0.3-0.5kWh per 24hrs in a...

@GafferTapeKing19 is right about the relay, but worth noting the contacts are rated pretty low — 4A max if I remember correctly.
@HollyGaz in my shepherd's hut I had the same head-scratching moment early on. What sorted it for me was making sure the BMV gets a proper full sync regularly — mine resets cleanly when the...

@LochChild great thread. One thing I'd add to what @MickDavies is touching on — don't overlook your battery monitoring once you've made the swap.

Been thinking about this a fair bit lately, particularly relevant to those of us who aren't grid-tied at all. For the narrowboat and the shepherd's hut, I've no export option whatsoever — so the...

Had this exact issue on my narrowboat last winter. Turned out to be the VE.Direct Bluetooth dongle rather than the MPPT itself — the dongle was dropping its BLE connection when temps dropped...
Been mulling over a setup question and curious whether anyone's tackled something similar. Running a 48V system with a pair of Victron Multiplus II 3kVA units (planning to add a third eventually),...
Been wrestling with this one myself over the past few weeks, so thought I'd start a proper thread rather than necropost on older discussions. My setup is a Victron Multiplus-II with a Cerbo GX,...
Had something similar happen with my Victron Multiplus-II 48/3000 when I first installed it last year — genuinely concerning when you've just dropped that kind of money and get absolutely...

@EcoFlow_Queen the 48V input range is the first thing I'd be checking in the actual datasheet rather than the marketing copy — these units often quote a wide PV input voltage but the MPPT tracker...
Jumping in while we wait for @DucatoDream to finish the thought too — Quick question for the thread generally: is this primarily a battery state-of-charge issue triggering the alarms, or is it...
