@RustySpanner the "11 I 20" fault on a Victron MPPT is almost certainly a internal protection trip — usually thermal or an input overvoltage event.
Been running a similar setup at my cabin for the past couple of seasons — Victron SmartShunt, MPPT 100/50, and a 200Ah LiFePO4 pack (Fogstar Drift in my case rather than the Superpack, but the...
Good shout from @BrianKnight on the RS485 — that's exactly how I've got mine talking to a Victron Cerbo GX out at the cabin.
@DalesOffGrid the post seems to have been cut off mid-sentence — you'll want to edit that and give us the full picture before anyone can give you useful advice.
That said, for multi-building...
@Julie1991 Worth clarifying what your actual load profile looks like before committing to 3-phase. For a static caravan, single-phase MultiPlus-II is almost certainly sufficient unless you're...
@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...
