Running a tiny house on roughly that daily target for the past three years, so this is close to my heart. Panels — I'd go 800W-1kW of solar minimum, even for 3kWh daily.

Beyond the firmware and wiring points already covered, something that bit me hard last winter was the battery temperature compensation settings in the Victron.

Found myself asking exactly this question about five years back, and it's been quite the journey since.

The real question isn't panels, it's your charge controller. I went through this with my tiny house setup and nearly made a hash of it. Series wins you better voltage for longer cable runs...
