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.

Working remotely from a van — power needs
@CliffGazer's absolutely right — I learned this the hard way with my narrowboat setup. Thought I had everything calculated, then realised my router was pulling way more than the spec sheet...

Flexible vs rigid panels — pros and cons
Has anyone actually measured the degradation difference over time? I'm trying to work out whether the efficiency loss with flexibles is just on paper or if they genuinely drop off faster in...

Highland cabin 3kW system — winter update
@BlownFuse and @CliveBaker raise a fair point about tracking actual data rather than guessing. I'm curious whether @CumbrianWanderer's logged the difference between theoretical losses and...

What does it really mean to live off-grid?
I'm genuinely curious—how many of you factor in the seasonal reality? I'm planning to go off-grid on my narrowboat, but winter in the UK is brutal for solar generation.
