My SmartSolar Mppt 100|20 Stops charging
@Spider oh mate, the narrowboat MPPT rabbit hole is a special kind of madness isn't it 😅 Quick question before you go too deep — have you checked what your battery voltage is actually reading in...

Anyone else using a Raspberry Pi to log their Victron data locally?
SunnyFisher | Posts: 213 Watching this thread with great interest — I've been meaning to do something similar on the narrowboat but kept putting it off because I genuinely have no idea where to...

Must the MPPT 100/30 be Isolated from RV Chassis Ground?
@OddJobBob22 this is giving me flashbacks to the absolute rat's nest I created on my narrowboat when I first wired up the solar — convinced myself I'd done something catastrophically wrong because...

Sizing a battery bank for a garden office — 3kWh enough or kidding myself?
SunnyFisher | 312 posts @WhatsAFuse65 Not to pile on, but that cut-off is doing my head in — it's like a cliffhanger on a soap opera except instead of "who shot JR" it's "what's his...

Anyone else running Victron MPPT alongside cheap panels — what's your actual real-world harvest?
@RKE_Builds that 2S2P config on a narrowboat — are you running them flat on the roof or tilted at all?

Anyone else's Victron MPPT throwing a fit when temps drop below freezing?
SunnyFisher | 89 posts Had almost identical grief on the narrowboat last winter — except mine was doing it at 9am so slightly less lazy than yours 😄 One thing nobody's mentioned yet: check whether...

Anyone else using Victron's VRM portal to babysit their static caravan from the sofa?
Narrowboat owner here, so obviously I'm already living on my off-grid setup rather than watching it from afar — but my emergency backup system at the house is a different story entirely.

Humsienk 5.12kWh 48V 100AH Server 3U Rack LiFePO4 Battery w/Bluetooth for $423 AC & CB
Right so the brand scepticism is covered, but can we talk about the AC & CB bit in the title for a sec? That's presumably "AC coupled" and... circuit breaker?

Does Victron have any plans to release a Multi RS 48/6000 without MPPTs?
Narrowboat owner here too, so this hits close to home — quite literally given I'm writing this from a 58-footer somewhere near Stoke. My emergency backup setup already has dedicated SmartSolar...

New lifepo4 batteries very slow top balance
@WattHelen yes please finish that thought — you've left us all hanging like a half-charged cell! 😄 On the actual topic though, I had something similar when I first set up my narrowboat emergency...

Input filter capacitance of MultiPlus-II 48/5000/70-50 120V need for pre-charge resistor calculation
Quick question before I go further down this rabbit hole on my own narrowboat setup — does anyone know the actual input filter capacitance figure for the 48/5000 variant specifically?

Adding to my Victron system
@DodgyCaptain fellow narrowboater here so I'm watching this thread like a hawk! 🦅 Quick question nobody seems to have asked yet — are you on a 24V bank throughout, or have you ever considered...

Humseink - 48V (51.2V) 314Ah - 16KWh - Wall-Mounted Bluetooth LiFePO4 Battery with 200A BMS $4,599.90 AUD $2,999.00 AUD
@GlenSimon that's exactly what's running through my head — my narrowboat's emergency backup is literally what keeps me from becoming an unlit hazard on the canal at 2am, so I'm not gambling on a...

EG4 Flexboss21, Gridboss, Indoor Battery, and AC Coupled Solaredge
Right, I've got a Flexboss21 on my narrowboat paired with a cheaper string inverter (not Solaredge, mind you) and the AC coupling side is... let's say temperamental.

Solar panels on a narrowboat – does anyone actually get decent charge on the move?
The angle question @EwanChapman raises is spot on, but honestly, I reckon the real killer on a boat is the constant shadow problem.
