Been scratching my head with something similar on my setup — Multiplus II with a Fronius on AC-IN, all loads on AC-OUT, pretty standard ESS config.
What I'm seeing in Venus OS is the grid figure...
Got a bit of an odd setup situation and could do with some input from anyone who's been here before.
Running a small off-grid build — basically a converted timber-frame tiny house — and I'm trying...
Been experimenting with charging my wife's Nissan Leaf from the motorhome setup and it's... interesting.
Seen this with my Drift too — tripped around 80% during EV charging sessions when the draw was spiking hard.

Had a Yamaha EF2200iS running alongside my Victron system for about two years now.
Worth adding — have you checked your battery state of charge at the start of those winter days? I found my setup was throttling output because the Fogstar lithium cells were already near full from...
Running almost the same stack on my tiny house — Pi Zero 2W pulling from a SmartSolar 150/35 and BMV-712 via VE.Direct to USB adapters.
One thing nobody's mentioned yet: cable length matters more...
Running a 48V 15kWh LiFePO4 bank (Fogstar cells, DIY build) in my tiny house and I've been experimenting with using my Nissan Leaf as a kind of secondary buffer.

@EcoFlow_Gal from my tiny house build — went hybrid (Growatt SPF 5000) and honestly the wiring simplicity alone was worth it.

Running a compressor fridge full-time in my tiny house setup — same pain initially.
@GoldenTrekker worth looking at the AC-in/AC-out2 setup if you haven't already — out2 can be configured as a non-critical load output that drops when you're on battery, which is almost a soft...
@BatteryJason and @CamperCarl have covered load well so I'll add the other bit nobody's mentioned — temperature.
Fogstar cells (assuming you're running their Drift or similar) drop voltage...
Been wrestling with something similar on my tiny house setup so figured I'd throw this out there.
Running a pair of Orion Smart TR 12/24-15 units in parallel to charge a 24V Fogstar Drift 200Ah...
Mate, that's a proper scare. The backwards wiring thing is so easy to do in a rush—I nearly did it on my tiny house battery bank before my mate spotted it.
Mate, it's the use case that matters. I'm in a tiny house setup and went batteries first because:
Silent operation (neighbours matter)
No fuel storage hassle
Works brilliantly for daily load...
