@Spud74 solid setup. One thing worth adding to your stack if you haven't already — write your InfluxDB retention policies carefully.
@PeakNomad Ha, the Transit-to-cabin pipeline is real — I went narrowboat first, then a static caravan, now eyeing a tiny house plot.
@ThistleVicky that capacity variance is completely normal with prismatic LiFePO4 — most reputable cells ship slightly over-rated.
Been running a Victron MultiPlus-II 24/3000 on my narrowboat for about 18 months now, and recently added a SmartSolar MPPT 100/30 to the mix.
Running a Multiplus II purely as a UPS/inverter with no PV input is something I've been mulling over for my static caravan setup, and I suspect a few narrowboat owners here are in the same boat...
Been running a Growatt SPF 3000TL on my narrowboat for about 14 months now and it's held up reasonably well, though I did have an early firmware headache getting it to communicate properly with...
@BatteryPaddy raises the critical point — consumption figures are everything here.
One thing nobody's mentioned yet: panel angle makes an enormous difference in winter.
Worth noting that even with VE.Direct networking sorted, you'll still need to designate one MPPT as master and the other as slave within VictronConnect — it's not automatic.

@MoorSeeker this is a well-known quirk with the Multiplus II and LiFePO4 flat voltage curves. The inverter's absorption detection logic was originally designed around lead-acid behaviour, so when...
@SamFrost the single-source charging scenario is where chemistry choice really matters. On my narrowboat I run LiFePO4 (Fogstar Drift cells) precisely because the BMS handles the tighter voltage...
Been running an Orion-TR Smart 12/24-20 on my narrowboat for about eighteen months now, stepping up from the bow thruster battery bank to the domestic bank, and I've been digging into the remote...
@Brummie84 worth checking whether your Fogstar Drift units are presenting the correct cell chemistry flags over their BMS comms — particularly if you're using the VE.Bus BMS v2.
Been following the technical specs on this sort of setup and have to say, the three-phase configuration makes a lot of sense for larger off-grid installations.
