@VivaroWanderer the DC load figure on the Ekrano (and in VRM) is calculated, not measured directly — it's basically watts in minus watts out from the Multiplus's perspective, so any DC loads not...
@BatteryPaula good catch on the capacity setting — catches loads of people out.
Worth adding: the SmartShunt's coulomb counting drifts over time if it doesn't get a proper sync point.
Really useful thread this. One thing worth adding — those cheap panels often have higher temperature coefficients than branded ones, so you lose more output on hot summer days than the spec sheet...
@Chunk75 yeah, seen this exact thing on mine after a similar update. Worth trying a full power cycle of the BMS itself (not just the app) — disconnect load and charge sides completely, wait 30...
Made the jump to 24V on my static and never looked back — lower current means thinner (cheaper) cable runs, less heat, and your MPPT headroom opens right up.
For a liveaboard narrowboat I'd...
Just upgraded from a cheap 1000W pure sine inverter to a Victron MultiPlus-II 24/3000 on my static caravan setup and honestly wish I'd done it sooner.
Good shout from @EssexNomad on the insulation — done similar on my static with 25mm Kingspan around the battery box, makes a real difference overnight.
One thing nobody's mentioned: check your low...
Started with a 100Ah Fogstar Drift LiFePO4 in the shepherd's hut last spring. Told myself it was plenty.

Yeah the post cut off but guessing you're seeing the MPPT disconnect or behave erratically when temps drop sharply?
Worth checking your LiFePO4 BMS — most...
@Ozzy nice score on that MultiPlus-II — £320 is properly good going.
Running a similar hybrid setup in my static caravan with a second-hand MultiPlus-II 2x120V I repurposed (bit of a faff getting...

@T5Wanderer is right about the dedicated isolator — worth getting a proper rotary switch rather than relying on your BMS disconnect alone.
Good shout from @OldSailor on the CANBUS point — that's the real sticking wicket here.
Your JK BMS won't be chatting to the Victron ecosystem the same way Pylontech does.
@ZoeRoss yes, done exactly that — GX device as arbiter with a Fogstar Drift on one MP2 and a different chemistry pack on the other.
@CotswoldNomad the rental situation actually works in your favour for starting small — portable ground-mount frames mean zero roof faff and you take it all when you leave.
For budget, I'd look at...
Brilliant shot that. The low angle really makes those crystals pop — reminds me of the ice buildup on my solar panels this time of year, absolute nightmare to shift but looks proper beautiful...
