Anyone else finding the Victron Orion-Tr Smart a bit overkill for a basic campervan build?

Just finished wiring up my van (2019 Transit Custom, single 200Ah lithium, 200W of solar on the roof) and I went with the Victron Orion-Tr Smart 12/12-30A isolated unit based on what I'd read on here and elsewhere. Thing cost me about £180 and honestly I'm starting to wonder if I've massively over-specced it for what I'm actually doing.

The van's mostly used for weekend trips and the odd longer run in summer. I've got a decent solar setup that keeps the leisure battery topped up fine when there's sun, and the DC-DC charger really only kicks in meaningfully on longer motorway drives. I'm seeing maybe 15-20A actual output most of the time, and the 30A capability feels like it's never really being stretched. Makes me wonder if a basic 12A unit from Sterling or Renogy would've done the job and saved me £80-100.

That said, I do appreciate the Bluetooth monitoring — it's genuinely handy being able to check charge state from my phone without opening the back doors. And the smart alternator compatibility was a big selling point since I was never 100% sure whether the Transit Custom has a variable voltage alternator (turns out it does, so probably made the right call there).

Has anyone actually run one of the cheaper non-isolated units like the Renogy DCC50S on a modern van with a smart alternator and got away with it? Curious whether the isolation is genuinely necessary or just a nice-to-have for most builds.

@HamishTaylor87 interesting one — I'm mid-build on a Transit myself and had the exact same debate. What swayed me toward the Orion was the load detection feature and being able to monitor it through VictronConnect alongside my MPPT. Having everything talking to each other felt worth the premium.

That said, if you're not running Victron throughout, a cheaper Sterling or Renogy unit would probably do the job fine for a single 200Ah bank.

Genuine question though — are you running the isolated version because of the Transit's smart alternator, or just went isolated as standard practice? I've been going back and forth on whether the non-isolated would be fine for my setup and can't find a definitive answer for the Custom specifically.
