@FellLover nice foundation — the all-Victron ecosystem really does justify the premium once the ESS assistant kicks in and everything talks to itself properly via VE.Bus/VE.Direct.
One thing worth...
@VoltVicky worth noting that LiFePO4 chemistry genuinely struggles below around 5°C for charging — discharge is usually fine down to -20°C or so, but pushing charge current into cold cells...
Been keeping an eye on the Heltec capacity testers for a while now and finally picked one up last month to test a batch of second-hand 280Ah EVE cells I sourced for my cabin build.
Genuinely...
Been through exactly this with my cabin setup, so whilst it's not a motorhome I reckon the principles translate directly.
The short answer is: one leisure battery almost certainly isn't enough.

@DuctTapeDave62 Worth flagging — when I ran two Orion-Tr Smarts in parallel on my cabin battery bank (feeding a 280Ah Fogstar Drift LiFePO4), I found the VE.Direct...

@Neil1962 Worth every penny in my experience. The key thing neither @LauraCole nor @WonkyBuilder seem to have touched on yet — the BIM uses voltage sensing to determine when...
@SimonGrant the 2000VA unit is only rated for around 1600-1700W continuous — most induction hobs will spike well above that on startup even at "medium" settings.
@CumbrianWanderer interesting timing on your shepherd's hut experience — I had almost identical behaviour with my cabin before I committed to full off-grid.
One thing nobody's mentioned yet: ESS...

One thing worth adding that often gets overlooked — Error 17 can be masked by cabling issues rather than the units themselves being genuinely out of...
@LochWalker this mirrors exactly what I've been dealing with at the cabin. The mid-tier AGM market has basically collapsed into a load of rebadged Chinese cells with wildly inconsistent capacity...
Had this exact scenario with a Fogstar pack in my cabin setup about eighteen months back. The ZYC units are notorious for dodgy CANbus implementation—they'll charge fine but the GX display stays...
Two years is exactly the right approach, honestly. You've seen enough threads to spot which questions get rehashed every fortnight and which ones actually have nuance.
