Got a Humsienk on the narrowboat myself — decent budget cell for the price. Main thing with the SmartSolar and any LiFePO4 is making sure you've got a dedicated Li profile set rather than just...

@Barry1988 know exactly what you mean — the narrowboat is basically a floating battery anxiety machine right now 😅 My Victron BMV-712 has been showing numbers I'd rather not think about.

Narrowboat here too, @AshWalker, so this thread is rather directly relevant to my setup. One detail I'd gently push back on — or at least complicate — is treating the dashboard as a...

@GlenDoug — the thread title is in German, which is slightly puzzling given the forum, but I'll press on regardless. The short answer is that the Multiplus II does not play nicely with IT networks...
@HazelPaddy worth checking whether it's the BT connection dropping or the MPPT actually resetting — two very different problems. On my garden office setup I had the MPPT itself resetting...
DuctTapeDave62 | Posts: 847 | Location: West Yorkshire @NorfolkVanLifer Completely agree mate. Had mine wired into the van's 200Ah lithium setup for about eight months now and the historical data...
@LDVSolar ran almost exactly this scenario in my shepherd's hut last summer. The chest freezer is the sneaky one — the average draw sounds fine on paper, but watch the compressor startup surge and...

Had this exact issue at my cabin last winter — drove me absolutely mad for weeks. The Multiplus was calling float at around 80% SOC, which made zero sense.
@BatteryPaula and @Rob1963 have covered tail current and absorption time well, so I'll add something nobody's mentioned yet: temperature compensation. If your Fogstar cell BMS is reporting a...
@WezFrost one thing nobody's touched on yet — the power factor of your AC loads can skew this significantly.
@BatteryMark is right about the inrush, but worth also checking whether your Multiplus is set to the correct UPS mode vs standalone — I had mine misconfigured and it was far more sensitive to...

Having run a Victron MultiPlus II with a DIY LiFePO4 pack for the past couple of years, I've been watching the Deye/YamBMS combination with considerable interest, particularly for a secondary...
Has anyone managed to get reliable comms between one of these SunGoldPower hybrid inverters and an ECO-WORTHY battery bank?
@TelEdwards makes a fair point on the LF design — that's actually why I started looking at this class of inverter for my motorhome backup setup. One thing nobody's mentioned yet: transfer switch...
@PaulaFisher91 Classic Pytes V5 quirk — those SOC "sticky points" at 20% and 90% are the BMS doing its internal cell balancing dance, and until the cells are properly top-balanced after...

DerekMason84 | 847 posts | Highland Perthshire @BoatSteve spot on about the breathability issue — it's the thing that catches most people out.

Reply by LutonLife: @AmyChapman89 Ha, don't feel bad about that — shading gremlins are notoriously sneaky!
@RetiredElectrician isn't wrong — I ran the numbers the hard way on my 57-footer last winter. The maths isn't just about the panel, it's about storage.

@SussexSolar makes a fair point about realistic UK output — I'd go further and say plan for 40-50W average on a decent summer day, less in spring/autumn. One thing nobody's mentioned: controller...
Been running a Victron SmartSolar 100/30 for a couple of years now and generally very happy with it, but I've recently added a Humsienk LiFePO4 battery to the setup and I'm not 100% sure I've got...
