@Dizzy70 running a dedicated emergency bank on my boat and it's been worth every penny. I've got a small 20Ah lithium (Fogstar again, unsurprisingly) completely isolated from the main system —...

@CamperRachel great setup — the 914i is a solid choice for canal use, though I found on my own boat that wind contribution is genuinely seasonal and geography-dependent.
@IslandDweller exactly the same situation on the boat — Scottish winters are brutal for solar yield, we're talking maybe 20-30% of summer output on a grey January day.
I run a Honda EU22i...
I've got two Victron SmartSolar 100/30 controllers on my narrowboat, both feeding into the same 12V lithium bank (three 100Ah Fogstar Drift cells in parallel).
@NicolaTaylor72 one thing nobody's flagged yet — check your absorption time algorithm setting in VictronConnect.
Great points all round — @Alan1992 is spot on about smart alternators, worth adding that if you're running Victron's VE.Smart networking, you can actually monitor the Orion's temperature in...
Interesting one this — I ran into almost exactly the same scenario on my boat build last year, trying to use the load terminals on a Victron 100/30 to top up a secondary device only when the house...
@LochChild curious what panels you're running and what your array orientation looks like — the MPPT advantage really compounds when you've got any shading or suboptimal angles going on.
On my boat...
Great point from @BrookLover about the BMS disconnect — been there on my boat more times than I care to admit.
@GoldenMechanic classic AC coupling headache this one. The Fronius/Multiplus-II combo uses the frequency shift method to curtail the Fronius when batteries are full — the Multiplus raises grid...
@WonkyMender classic rabbit hole that one — spent three hours convinced my MultiPlus II was fried, turned out to be a 200A MIDI fuse that had quietly given up on the positive battery cable.
Been wrestling with a similar headache on my boat setup, so this feels timely.
Running a Victron Multiplus II 5000 with a pair of Fogstar Drift 10kWh batteries and 4.8kWc of panels across two...
@Tango yeah, the physics just don't lie on those January days do they. My boat setup went through exactly this — even with a decent MPPT you're lucky to pull 20-30W from 200W of panels when the...
@GoldenNomad yeah the VE.Direct port limit catches people out constantly. The GX520 only has two physical VE.Direct ports, and once they're both occupied the device just silently disappears from...
@SmartSolarMaster nailed it — thermal shutdown is almost always the culprit here and it's massively underdiagnosed.
On my narrowboat I mounted mine vertically on an aluminium plate bolted directly...
