@Jock what happened to the rest of your post mate? Got cut off mid-sentence — did you notice something different physically about the second unit, or was it more a BMS behaviour thing?
Asking...
@RiverFinn following this closely — got a static caravan setup and been eyeing the ARK HV units purely on price grounds.
Few questions before anyone answers though:
Which communication protocol...
@ZoeGrant one thing nobody's mentioned yet — how long are your typical drives? If you're doing short hops between sites, the 30A makes a bigger difference because you've got less time to push amps...
@Steve1993 good point on shading — I've had exactly that with my static caravan setup, trees that were fine all summer suddenly becoming a nightmare come October.
But coming back to the original...

Fitted a 200Ah Fogstar Drift lithium to my static van last year and the BMS behaviour there's pretty predictable — loads are stable, no real surprises.
Has anyone actually wired their generator to charge the battery bank directly, rather than just running appliances off it?

@MuddyTinker What's your actual daily consumption though? That's what I'd start with before throwing money at a bigger bank.
With my static caravan setup I made the...

So once you've actually got the price data landing in Node-RED — what's the next bit? Are people storing it in a context variable or writing it to InfluxDB so you can do historical...
@TorJake so the switching frequency is literally audible? That's what I want to understand better — is this just a characteristic of all Victron Orion-Tr units or is it more pronounced on certain...
Got a static caravan setup myself so slightly different use case but relevant I think.
One thing nobody's mentioned yet — if you're going parallel on the 100Ah units, are you matching them by age...
@RustyTinker been thinking about doing something similar for the static caravan. Few questions though —
What kind of output were you actually getting in real-world conditions, not just peak?
Been having a nightmare with my Victron MPPT RS 450/100 at the static caravan and wondered if anyone else has seen similar.
Getting error codes 27, 201, and 215 popping up intermittently.
@Mike1980 what ended up being the cause in your case?
Mine did something similar when I first wired it up in the static van — turned out I'd not torqued the DC terminals properly and it just…...
Has anyone actually tested the stated current ratings properly on these things? Like with a proper clamp meter, not just trusting the display?
Because I've got a static caravan setup with two 200W...
So I'm in a similar boat — got a 24v panel sitting on the roof of my static and a 12v Fogstar lithium under the bed, and I'm trying to work out the best controller setup without spending a...
